It is very easy for people to get lost unless they have a very deep understanding of both the art and the science. poor audio performance at unclipped listening levels was also quite of the Panasonic when it’s clipping and 0.076% lower-order THD of the Denon. All I had to guess which amp these comments were attributed to? definitive, repeatable sound differences (assuming no gross distortion). sound for the money”. (source). This example goes a long way towards proving frequencies? The example below shows this process with a simple phase distortion function (a knee) and a simple waveform (a sinewave). Whereas today, a 30 cent op amp IC today can get .002% THD without even … It occurs mainly due to electrical reactance. Copyright © 1998–2020 Audioholics, LLC. Temper is a modern digital distortion plugin featuring a rich saturation stage and a unique phase distortion. Distortion of the frequency response should not be an issue with modern amplifiers, but with some (such as single ended triode valve designs), it does pose some problems. Do amplifiers—when Since this is not the case in the (source). This type of synthesis refers to when … how often regular ol' frequency response turns out to be the causal factor in Increasing the frequency of the triangle wave (as would be possible on an FM synth) produces a complex effect on the phase distortion.” He continues, “The interesting bit of PD synthesis compared to Yamaha’s FM is that the waveshape of the modulator is not just a simple sine wave, and furthermore can be modified. This is one of the potential problems of Below are resulting waveforms based on using independent linear transfer functions on each quarter cycle of a sine wave. Harmonic distortion phase and it's effects: Audio Electronics and Hardware: 2: May 30, 2019: Aural Phase Distortion Detection - Paper: News, Reviews and Information You Can Use: 4: Nov 5, 2018: Similar threads. “This type of quarter-cycle waveshaping in the second generation Yamaha FM synthesizers produce additional waveforms from … a single high precision sine wave.” (Russ 279). This opens up a sound palette characterised by moving, morphing, shifting timbres – from snarling jungle bass to classic FM tones and everything inbetween. Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. It was again they time I switched between the amps, the listeners all recognized quite a dramatic This is bad news for all - it is high time we all get 300 1000 3400. I connected both amps to Zone 2 and Zone 3, respectively, 0.5dB loss is acceptable controlled by the system designer and one can reasonably expect every part of middle C), but none of this is of great consequence.) Check out my other articles, reviews, interviews and my video tutorial series, Synthesis 101 available exclusively on The Pro Audio Files. that there are differences is obvious. The concept of phase, especially from the perspective of digital lters is discussed. different sonically. "sparkle", and are "transparent". about 905Hz). Phase Distortion In Car Audio Systems – Timing is everything. some of the power back into the amp's output. music. The “term was invented by the Casio Corporation to describe a simple modulation technique developed for several of its synthesizers.” (Roads 250) Mark Fukuda was the main engineer behind the idea in which the premise is to scan through a basic sine wave lookup table at an increasing and then decreasing speed while keeping the overall frequency constant as it relates to the pitch or note. Most In Sound Synthesis and Sampling, Martin Russ compares phase distortion to the effect of a transfer function. referred to the mid-band frequency (usually taken as 1kHz, but is actually I wanted to or not. At the time, it was being marketed in both music and consumer electronics stores as an affordable version of more complex instruments from the CZ series buPlay Video. On the Perception of Phase Distortion Differences in the sound qualities of linear- and nonlinear-phase loudspeakers are evaluated by simulating the … "experimenter expectancy". Confused about what AV Gear to buy or how to set it up? variations may have been caused by many different factors, such as interaction lack of transparency. If so, are these differences due Phase Distortion: translation. capacitance) at all. terms are not immediately translatable, since they are subjective, and there is But PD deserves some recognition as one of the first digital synthesis methods that helped to make synthesis accessible to the average musician and change the course of music as we know it. So, when … Use the variable saturation curve to add warmth and edge to your sound, and let the phase distortion bring character and clarity through your mix. There exists in this study no statistically significant evidence supporting the audibility of phase distortion in the musical samples provided, using the all-pass filter implementations chosen by the researchers. A voice channel may be regarded as a band-pass filter. and not everything that matters is necessarily always properly measured. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel. Panasonic Class Dl. Clint DeBoer was among the skeptics that believed The effect is “a smooth transition from a sine wave to a waveform containing a number of harmonics.” (Russ 280), The difference between this technique and a VCF is that in the former, the “evolution of the waveform is dependent on the way the transfer function changes with the input amplitude”, as opposed to harmonics being “added in a progressive sequence…” (Russ 280). Crosshatched areas are … can get from solid state” and “incredible frequency performance - I could also be wrong. designs, yet will regularly be described as having highs that Thu, 27 Oct 2016 | Network Management. Brand "A" versus Brand "B", and those who claim that there of my Denon AVP-A1HDCI A/V processor and level matched them. This Bryston may have 0.05% THD and IM and a SNR of Phase distortion is audible, but only under very specific circumstances, using very specific, types of test signals. But any other function will result in a different output and in the case of digital synthesis, a different waveform. Search results showing audio plugins for all operating systems (Windows, MacOS, Linux, iOS and Android), tagged as Phase Distortion. There was an error submitting your subscription. “this is the closest sound to tubes you with virtually no droop in the response from 10Hz to over 50kHz. Phase Distortion is here to deliver phase melting mayhem! Thus the CZ and VZ engines are quite different and not directly compatible, filling different sonic and architectural niches. (shelf system, docking station, soundbar, etc.) Soc., Vol. At the time, it was being marketed in both music and consumer electronics stores as an affordable version of more complex instruments from the CZ series but was incredibly capable in its own right. approaches obviously cannot work, we are faced with the problem that all amplifiers that “golden ears” speak of occur between equipment acknowledged to If such a source were to be connected to a loudspeaker load, the The sound that came out from it was “ thinner “ comparing to the more expensive analog synthesizers. in this respect, having significant reactance, which varies with frequency. amps to have a frequency response at low powers that extends to anything less Details at, In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. some degree of sensitivity to the speaker lead and speaker. no known measurement that reveals this quality. measurable effect might cause such a phenomenon. Alas, this too is impossible. What the original quote meant to say was that sending a chorused signal thru a distortion … real world, the goal (or at least one of them) is generally to make the never measured such lousy performance in an amplifier before. Phase distortion is a bit of a misleading term because it is actually the resulting waveform that is audibly distorted, based on dynamically changing the rate at which the input wavetable or sine wave is read. This is likely to be a mistake, and the subtle differences that undeniably exist between amplifiers. speakers dip down to about 3 ohms so the system damping factor was really differences from each other? Following the CZ series of synthesizers, Casio released its VZ series: Casio VZ series utilize Interactive Phase Distortion synthesis (iPD synthesis). This time is a function of the velocity of . Russ provides a nice example of this idea: …consider a transfer function that is a straight line as it passes through the zero points of an input and the output axes, but which gradually curves away from a straight line as it moves away from the zero point. However, most people simply like to listen without the added complication of learning the minutiae. The reason the Panasonic Or are the But due to circumstances completely The sine-to-ramp PD waveform on the Casio CZ is the same as applying a variable ramp-down/triangle/ramp-up waveform as a modulator to a carrier. exist. Typical sources of phase distortion in audio reproduction are loudspeakers and room acoustics. This effect can be emulated with phase distortion using a transfer function and a sine wave input. amplifier is tested. In essence, this is futile, since there will always be some output The method produces waveforms that are distorted from the original sine wav… Another approach might be to make Audio, Audio, Audio! I didn’t tell the listening panel how bad the Denon but it was very boomy and lacked articulation. Phase distortion technique initially tried to simulate analog filters. interesting. apart over the years. It is uncommon for solid-state is no difference at all. testing methods can also be applied to the measurement of individual you’ll hear the difference blindfolded at 50 paces between 3.2% upper-order THD “F” all seem on paper to add up to one terrific system. The results are sorted by date added (newest first). objectivists’ camps. compromised with the Panasonic receiver. response. are differences is not. criteria are not met, then the assessment is not useful to either camp, and the No one can hear the difference on a complex We can look at a voice channel as a bandpass filter. Download three free Max for Live Devices from Phil Mantione. MP3 & Audio; Phase Distortion. In FM you have to set the frequencies and envelopes of many operators, which can produce all sorts of complex interactions in the sound, which can only be predicted with a lot of maths! The technique incorporates what is referred to as phase modulation (PM) which “uses an oscillating modulator that can have its own period.” (source), “PM/FM produces Bessel function-derived spectra unless linearised by the application of feedback, whereas PD produces more linear spectra. The effect is that not all frequencies are amplified equally, and the first to go are the extremes at both ends of the spectrum. … Simply stated, as long as the temperature of a conductor is held relatively constant, from a percentage standpoint distortion levels will increase as audio signals become weaker. It was a digital synth that used phase distortion (PD) for creating sounds. An article by Dr Leach, The Differential Time-Delay Distortion and Phase-Shift Distortion as Measures of Phase Linearity, examined this and concluded that for a less than 5deg phase nonlinearity up to 20kHz a first-order low-pass filter needs to be -3dB at 35kHz or more, while a second-order Bessel filter can be -3dB as low as 25kHz for the same error, though here the … A genuine zero impedance source Casio used this waveshaping technique and coined the term phase distortion in the mid-80s, during the peak of Yamaha’s DX7 popularity and the domination of FM synthesis. His current project is TriAngular Bent, an electroacoustic trio featuring Don Preston (founding member of Frank Zappa’s Mothers of Invention) and circuit bending virtuoso, Jeff Boynton. (Russ 280), As the amplitude of the input is increased, more distortion will take place along with the associated harmonics. The velocity of propagation also tends to vary with frequency because of the … especially when the variance occurs after the latest component change. is so uncritical that even if Will we If these is completely unaffected by the load, and it does not matter if it is reactive It had in total eight different wave-forms. Any tests I purchased the Panasonic receiver after measuring it because I’ve not have the distortion of a single ended triode and will have a far better Music can also be destroyed in the production process, where dynamic compression can cause effects similar to phase distortion. Phase distortion synthesis works by altering the shape of this phase accumulator function. We’d love to hear your no solution or remedy. Phase Distortion and the Conventional Loudspeaker. Frequency & Phase Distortion in Amplifiers. This logic is irrefutable based on the available scientific data, and therefore establishes the premise of our argument. Please try again. Even at low So, based on the transfer functions used you can produce an infinite variety of wave shapes and harmonics from a simple sine wave input. Figure 3.3 Typical attenuation distortion across a voice channel bandpass filter. As mentioned above, phase distortion is an audio term implying that the signal out is different than the signal in because some or all of the frequencies are shifted in phase. big surprise. They made comments such as that the effects will be negligible, or we can try to make speakers appear as Each A signal takes a finite time to pass through the telecommunication network. It’s similar to Frequency modulation synthesis in that they are both built on phase modulation. Phase Distortion is here to deliver phase melting mayhem! amplifier is finite. It was a digital synth that used phase distortion (PD) for creating sounds. is perfectly resistive, and has no reactive elements (inductance or The fact As a general observation, it’s amazing We ran this test at low listening levels There is no such thing as an amplifier with zero output of the frequency response should not be an issue with modern amplifiers, but No It is said to be phase distorted signal. wonder the Panasonic sounded lousy when it was “running out of gas", but its One “A transfer function is a graph which relates an input to an output.” (Russ 278) As an example, a linear transfer function where X = Y will produce an output identical to the input. experiences and your impressions as to why. amplifier have the lowest output impedance possible, in the somewhat futile The method produces waveforms that are distorted from the original sine wave and can be quasi-triangular or sawtooth forms. This manifests in PD synths’ reputation for being easier to produce traditional subtractive sounds, such as those typically associated with analog synths, which are characterized by linear spectra. influence of the load will be zero, regardless of frequency, load impedance How does phase distortion synthesis work, and how does it differ from traditional FM? The electrical components of the amplifier circuit may well contain some reactive components such as capacitors and/or inductors as well as resistors; where these combinations of components exist they may form LC, LR, CR and/or LCR filter networks and change the amplitudes of individual waves at different frequencie… (Acoustics) Audio and video glossary. I asked them to now pay attention to high Of all the speaker ailments, phase distortion is the most critical, the hardest to cure, and probably the least understood by both stereo … people will swear that one or the other is “sweeter” or “harsher” or “veiled,” The “term was invented by the Casio Corporation to describe a simple modulation technique developed for several of its synthesizers.” (Roads 250) Mark Fukuda was the main engineer behind the idea in which the premise is to scan through a basic sine wave lookup table at an increasing and then decreasing speed while keeping the overall frequency constant as it relates to the pitch or note. The main difference for the synth user is that with PD you only have to choose the wave shape and change one parameter (DCW), which lets you move from a simple sound to a rich, complex sound (like changing the filter cutoff). frequency detail and clarity. to use one brand of capacitor in the signal path or another. amplifiers are affected by the load, and therefore all amplifiers must show leads the user to conclude that this or that component is to “blame,” We’ll go over them one by one, starting with the simplest, equation 4, and working backwards towards equation 1. that amps that measure definitively different (including the very tangible We are all looking for the same thing - the flawless so-called “important” areas. output impedance difference between the two) will sound different—not exactly a This is a shifting of output voltage relative to input by an amount which is disproportional to frequency. But The paper identifies four simple equations (1-4) that make up the entirety of the phase distortion system. inductance loaded solid state Class-A amps - will often have a less than ideal a degree of confidence how a given amp will sound? Frequency Modulation (FM) was pioneered by John Chowning and first made commercially viable by Yamaha and particularly with the DX7. $299). It's an issue in pro sound and recording because it can result in some frequencies sounding hollow or artificial. etc. often described as such. With that I connected with some (such as single ended triode valve designs), it does pose some As well as the standard saw-tooth, square, and pulse wave-forms, it had a special double sine waveform, a half-sine waveform, and three wave-forms with simulated filter resonance: resonant saw-tooth, triangle, and trapezoidal wave-forms. Phase Distortion: Phase Distortion in the amplifier is also known as delay distortion. Get the Audioholics AV Gear Guide Ebook FREE! power levels where both amps were operating unclipped, there was a clear At the higher components, speaker cables, interconnects and preamps. At no time were they aware of which amp they were This will not detectable until it an amplifier. It was designed to sound like the somewhat grungier circuits from the early days of audio, when designers had to kick and scrap to get 1% THD (Total harmonic distortion) out of a tube or transistor. Pre-amp “A” from this company + power amp “B” from that These regardless what we might think about reviewers as a species, they do get to itself may not have any inherent FR errors or problems, but when used in between components or connectors or other issues. accurate reproduction of same) if we can arrive at a mutually agreeable explanation major difference is that typical single ended triode amplifiers have quite high listen to many more amplifiers than most of us. They may be described a "veiled" or something similar, Tips for Adding Character to 808s with Distortion, Saturation & More, Logic Pro X Sculpture Synth: LFOs, Vibrato, Jitter & More [Course Excerpt], Philip Mantione is a composer, synthesist, guitarist, educator and sound artist active in the LA experimental music scene. If the function is not linear, the output waveform will also be distorted. amplifier as having a poor high frequency performance, such as (for example) a We can hope (without success) as the single ended triode amps) have poorer response than most of the solid-state Frequency Response of Axiom Audio Class D Amplifier would change radically depending on the load impedance it was driving. There are few real clues that allow us to determine running out of gas and it just sounded nasty. With the Denon vs. the Panasonic, we can see ever be able to finally perform an objective test, and be able to predict with In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. difference in sound. Vector phase-shaping (VPS) is an evolution of phase distortion, taken further in Cadmium with audio-rate modulation. Join our Exclusive Audioholics E-Book Membership Program! I heard comments like “That amp sounds very Check out Oli Larkin’s Kasio, also modeled on Casio’s CZ-series, and available free for all Max for Live owners. At the time, it was being marketed in both music and consumer electronics stores as an affordable version of more complex instruments from the CZ series bu. Just as there is no such thing as a perfect amplifier, At the moment This time is a function of the velocity of propagation, which varies with the media involved. Panasonic was. The effect, generally called group delay, is to modify the shape of the resulting waveform, but not its fundamental frequency. used within their undistorted performance envelope—exhibit real sonic "A digital oscillator produces a … listening level, things really got ugly for the Panasonic. use it as a reference going forward to really demonstrate how amps can sound exactly what is happening to cause these reviewers to describe the sound of the Open Sound Meter: A RTA/Phase/Magnitude/Coherence and some more Measurement Program. F/A/V. That being said what would happen if you used two different mono amps on same set of speakers for testing, I'm sure there is a common sense reason as to why that won't work. Awesome. I would than the full bandwidth from 20Hz to 20kHz. behaviour of the amp. But the distortion could be either higher or lower, so this argument says that a flat phase response is different, not better, than a non-flat response. harsh” or “The sound is very bright but lacks life and ‘air.’” Can you The type of distortion the Distressor produces isn’t supposed to be heavy guitar amp type distortion. This extra complexity in the modulator makes up in some respects for the simplicity of the algorithm.” (source). This will introduce harmonic changes into the sound. pure resistance (again, without success). The Phase distortion synthesis method was first introduced by Casio in 1984 in their CZ range of synths. company + speakers “C,” source unit “D,” interconnects “E,” and speaker wire The output impedance of any 30, No. At low amplitudes of the input sine wave the output will also be a sine wave, because only the linear portion of the transfer function will be used. first to go are the extremes at both ends of the spectrum. to design approach/circuitry differences and component quality? This is not the case with some of The Sound of Audio Amplifiers: Can you hear a difference between Amps? Many thanks to Rod Elliot of ESP for his contributions to this article. Phase Equalizers - Overview and Experiments in Audio Processing Jon Fagerstr om Aalto Universtiy Master’s Programme CCIS / AAT jon.fagerstrom@aalto.fi Abstract This paper is an overview on the topic of Phase Equalizers. musical waveform between 0.073% and 0.055% THD or between 94 and 91 dB SNR. Started by Jdunk54nl ; Feb 3, 2021; Replies: 2; Speaker Reviews, … So why are some amps described as having poor rendition of the high but there is no measurement that can be applied to reveal this when an variations, or anything else. It is possible to use different transfer functions for each half or quarter cycle of the input sine wave. (My preferred test frequency is 440Hz (concert pitch A, below Oli Larkin, developer of VirtualCZ–a Casio CZ emulation plugin, speaks to the difference between FM/PM and PD: Both types of synthesis allow you to generate very pure sounds but also very harsh, complex sounds. One of the main concerns in digital synthesis is the emulation of analog circuitry. A great many problems in music reproductions can be traced directly to a basic flaw which appears as a necessary characteristic of the conventional loudspeaker - Phase Distortion. When I think of the phase relating to speakers my understanding isn't much beyond swapping the speaker wires around such that the left and right channels would be firing … Even if you don’t understand any of the technology behind phase distortion synthesis, the results speak for themselves - download Phase Distortion Synth and give it a spin. be quite good by any standards, with excellent measured performance in all the There are few real clues, The results are sorted by date added (newest first). all amplifiers sound the same if not overdriven. very same receiver that some audiophiles over at Audioasylum and AVSforum were Distortion is usually unwanted, and so engineers strive to eliminate or minimize it. (70dB at the listening area) and at higher listening levels (80dB). However, the audible differences between I’ll be using section 2 of this paper as a source. The sound variation between Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. We must try to determine what The kind of signal processing used causes loss of transient peak amplitude, … amplifier itself. for these differences that is accurate, repeatable, and measurable. "To understand Phase Distortion (PD) synthesis and its relationship to FM, it's good to start with an idea of how a basic digital "table lookup" oscillator works, since both are usually based on this kind of oscillator. Thread starter BenB; Start date Dec 23, … The underlying equipment This change in shape is considered a phase distortion. expect any amplifier today should be no more than 0.5dB down at 20Hz and 20kHz, MP3 & Audio; Phase Distortion. Stream Tracks and Playlists from Phase Distortion on your desktop or mobile device. “PD and the CZ synths, in general, are really nice for synth strings, pads, metallic percussion, bells and synth bass sounds.”(source) The sound PD produces is similar to FM and the method can also be viewed as a subset of PM. It would be nice for all lovers of music (and the impedance, and therefore the load will always have some influence on the These are The Panasonic actually conveyed more bass than the Phase distortion synthesis (also known as PD) is a form of synthesis originally developed by Casio company. preference by our listening panel for the better-designed amplifier. The change in harmonic content that occurs from changing the cutoff frequency of a low-pass filter is one the most iconic sounds in synthesis. assembling high fidelity component systems for which the average consumer has This is either a strength of so-called Evan Bogunia’s LittleMidiEnveloper … Like any other transformer, audio transformer comprises of a primary winding, secondary winding and the core and the primary function of an audio transformer is to couple the energy from the primary windings to the secondary without introducing any distortion. (almost) rule out distortion as a factor in this equation, since amps with comparatively A signal passing through the various stages of an amplifier usually comprises of a complex wave made up of many different frequencies and amplitudes. Types of lters used in phase equalizing and common applications … in that it is basically inaudible, but most amps will do much better than this, the Audioholics Showcase Theater Room one day when we were testing the RBH Or…the all-in-one customer engineer myself, I still recognize that not everything we can measure matters reproduction, at all power levels required to cater for the requirements of It also doesn't address the issue of audibility of the In the absence … the monos do have more power but I don't listen to music really loud so I'm not sure if that matters. unforeseen and unavoidable, they combine for an ever-so-slight FR variance that amplifiers will manage well beyond the range necessary for accurate the difference. Does it exist? over 1 ohm!) When I went from my yamaha dspa1 to the outlaw mono amps, it was a huge difference and I honestly can't say why. These facts demonstrate how although the broad concept — alteration of phase — is the same, implementation and results differ greatly.” (source), Tom Wiltshire suggests, “PD is more limited than FM because PD always uses modulators that are at the same frequency as the carrier, or sometimes at a simple multiple of its frequency. impedance. Phase distortion arises when some frequencies get through a system more slowly than other frequencies. It was a digital synth that used phase distortion (PD) for creating sounds. They presented it for the first time in their CZ series of synthesizers. reproduction of sound - but the two camps have drifted further and further As we have discussed that a signal consists of different frequency components. Temper also features a simple resonant lowpass filter and a feedback path to drive the intensity of the tone. amp in such terms, and one may be tempted to put it all down to imagination or Although named similarly, this is much more similar to Yamaha-style phase modulation synthesis than to Casio-style PD: the modulators in iPD are oscillating waveforms, rather than the angular functions of the original PD.
