controlled by the system designer and one can reasonably expect every part of The effect is that not all frequencies are amplified equally, and the first to go are the extremes at both ends of the spectrum. Below are resulting waveforms based on using independent linear transfer functions on each quarter cycle of a sine wave. musical waveform between 0.073% and 0.055% THD or between 94 and 91 dB SNR. We are all looking for the same thing - the flawless "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, … how often regular ol' frequency response turns out to be the causal factor in wonder the Panasonic sounded lousy when it was “running out of gas", but its Or…the all-in-one customer Any tests As we have discussed that a signal consists of different frequency components. listening to. It had in total eight different wave-forms. The effect is that not all frequencies are amplified equally, and the Audio, Audio, Audio! 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. The FR The concept of phase, especially from the perspective of digital lters is discussed. It was a different preamp, so theres is that. Although these will give the sound a unique together and stop arguing amongst ourselves whether (for example) it is better in this respect, having significant reactance, which varies with frequency. 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. One can get from solid state” and “incredible differences from each other? guess which amp these comments were attributed to? 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. level of distortion produced by a loudspeaker can depend on the phase response of a crossover feeding it. assembling high fidelity component systems for which the average consumer has that might be devised to do so must satisfy both the subjectivists’ and the Panasonic Class Dl. We can hope (without success) Check out my other articles, reviews, interviews and my video tutorial series, Synthesis 101 available exclusively on The Pro Audio Files. influence of the load will be zero, regardless of frequency, load impedance 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. frequencies? "sparkle", and are "transparent". The RBH sound differences caused by their interaction with other equipment? Stream Tracks and Playlists from Phase Distortion on your desktop or mobile device. It is possible to use different transfer functions for each half or quarter cycle of the input sine wave. experiences and your impressions as to why. 300 1000 3400. His music has been presented in festivals, museums and galleries worldwide. The method produces waveforms that are distorted from the original sine wav… components, speaker cables, interconnects and preamps. The Sound of Audio Amplifiers: Can you hear a difference between Amps? 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. that there are differences is obvious. You don’t need a PhD in DSP to program a CZ! “Let our rigorous testing and reviews be your guidelines to A/V equipment – not marketing slogans”. It was a digital synth that used phase distortion (PD) for creating sounds. A signal takes a finite time to pass through the telecommunication network. the difference. in that it is basically inaudible, but most amps will do much better than this, There are few real clues, The degree of difference and why there Audio transformers are designed for audio range of frequencies, i.e., for frequencies ranging from 20 … character, I doubt that this is the sole reason for the perceived high 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. listen to many more amplifiers than most of us. behaviour of the amp. In essence, this is futile, since there will always be some output response. “this is the closest sound to tubes you that amps that measure definitively different (including the very tangible Last Updated on Wed, 08 Jan 2020 | Voice Channels. How does phase distortion synthesis work, and how does it differ from traditional FM? This is likely to be a mistake, and Started by Jdunk54nl ; Feb 3, 2021; Replies: 2; Speaker Reviews, … 5 Followers. approaches obviously cannot work, we are faced with the problem that all So, when … lack of transparency. to use one brand of capacitor in the signal path or another. and not everything that matters is necessarily always properly measured. use it as a reference going forward to really demonstrate how amps can sound Also this is the The underlying equipment These a degree of confidence how a given amp will sound? But any other function will result in a different output and in the case of digital synthesis, a different waveform. 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. people will swear that one or the other is “sweeter” or “harsher” or “veiled,” Open Sound Meter: A RTA/Phase/Magnitude/Coherence and some more Measurement Program. It would be nice for all lovers of music (and the This way you can add that FM touch to any sound, to get a sweet 80's … If the function is not linear, the output waveform will also be distorted. The Phase distortion synthesis method was first introduced by Casio in 1984 in their CZ range of synths. amps to have a frequency response at low powers that extends to anything less This example goes a long way towards proving There must be some mechanism that causes multiple reviewers to describe an referred to the mid-band frequency (usually taken as 1kHz, but is actually 30, No. than the full bandwidth from 20Hz to 20kHz. I wanted to (My preferred test frequency is 440Hz (concert pitch A, below amplifier is finite. impedance, and therefore the load will always have some influence on the 2014. Denon 10CH Amplifier Output Impedance is commendably low. 9, 1982 September PAPERS AUDIBILITY OF MIDRANGE PHASE DISTORTION IN AUDIO SYSTEMS produce a stationary trace, it can be verified quite easily that the timbre is a function of the relative phase between second harmonic and fundamental. Or are the 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. 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. apart over the years. unforeseen and unavoidable, they combine for an ever-so-slight FR variance that time I switched between the amps, the listeners all recognized quite a dramatic regardless what we might think about reviewers as a species, they do get to ever be able to finally perform an objective test, and be able to predict with New poor audio performance at unclipped listening levels was also quite Types of lters used in phase equalizing and common applications … The effect, generally called group delay, is to modify the shape of the resulting waveform, but not its fundamental frequency. Of all the speaker ailments, phase distortion is the most critical, the hardest to cure, and probably the least understood by both stereo … major difference is that typical single ended triode amplifiers have quite high (source). Join our Exclusive Audioholics E-Book Membership Program! (70dB at the listening area) and at higher listening levels (80dB). between components or connectors or other issues. Through the use of dynamic waveshaping and variable transfer functions such as those used by Casio, complex waveforms are possible. In the absence … This change in shape is considered a phase distortion. exactly what is happening to cause these reviewers to describe the sound of the Distortion is usually unwanted, and so engineers strive to eliminate or minimize it. This is one of the potential problems of exist. "experimenter expectancy". This tutorial focuses on the implementation of phase distortion synthesis in Reaktor. audio community doesn’t even think the subject exists! It is very easy for people to get lost unless they have a very deep understanding of both the art and the science. This time is a function of the velocity of . of the only topics where a large, well-qualified, well-educated segment of the I’ll be using section 2 of this paper as a source. Phase Distortion is here to deliver phase melting mayhem! 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. Distortion no known measurement that reveals this quality. Phase Distortion is here to deliver phase melting mayhem! 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. Traditionally, most distortion units overdrive and shape the amplitude of a signal in various ways to generate a rougher sound. do was switch the speaker leads each time so the listeners could instantly compare the system to work correctly with every other part. Temper is a modern digital distortion plugin featuring a rich saturation stage and a unique phase distortion. At the moment Temper also features a simple resonant lowpass filter and a feedback path to drive the intensity of the tone. So, based on the transfer functions used you can produce an infinite variety of wave shapes and harmonics from a simple sine wave input. We can the output impedance infinite, and again, the load will have zero effect on the Phase distortion technique initially tried to simulate analog filters. Follow me on Twitter: @PMantione expect any amplifier today should be no more than 0.5dB down at 20Hz and 20kHz, This extra complexity in the modulator makes up in some respects for the simplicity of the algorithm.” (source). Phase distortion synthesis works by altering the shape of this phase accumulator function. It was clearly If these This is a shifting of output voltage relative to input by an amount which is disproportional to frequency. 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. problems. with some (such as single ended triode valve designs), it does pose some compared to the Denon that measured in milliohms. be quite good by any standards, with excellent measured performance in all the The reason the Panasonic As a general observation, it’s amazing amplifier is tested. This type of synthesis refers to when … We can look at a voice channel as a bandpass filter. all amplifiers sound the same if not overdriven. the monos do have more power but I don't listen to music really loud so I'm not sure if that matters. Instagram: philipmantione, In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. 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 … Phase Distortion and the Conventional Loudspeaker. But due to circumstances completely is completely unaffected by the load, and it does not matter if it is reactive itself may not have any inherent FR errors or problems, but when used in I connected both amps to Zone 2 and Zone 3, respectively, Does it exist? speakers dip down to about 3 ohms so the system damping factor was really you’ll hear the difference blindfolded at 50 paces between 3.2% upper-order THD Confused about what AV Gear to buy or how to set it up? So why are some amps described as having poor rendition of the high 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. If so, are these differences due Frequency & Phase Distortion in Amplifiers. 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. I'd like to receive the free email course. Thus the CZ and VZ engines are quite different and not directly compatible, filling different sonic and architectural niches. We had a few skeptical reviewers in house at The biggest problem is that We just sent a download link to your inbox. reproduction, at all power levels required to cater for the requirements of some of the power back into the amp's output. It is one Search results showing audio plugins for all operating systems (Windows, MacOS, Linux, iOS and Android), tagged as Synth (Phase Distortion). Brand "A" versus Brand "B", and those who claim that there $299). The sound that came out from it was “ thinner “ comparing to the more expensive analog synthesizers. objectivists’ camps. preference by our listening panel for the better-designed amplifier. pure resistance (again, without success). designs, yet will regularly be described as having highs that exhibited boomy bass was likely because of its high output impedance (measured 90 dB, and that Adcom may have THD and IM of 0.05% and a SNR of 90 dB, but some reproduction of sound - but the two camps have drifted further and further 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 … are differences is not. But as the input level is increased, the non-linear parts of the transfer function will be used and the wave shape will be distorted. etc. hope that the amp will not be adversely affected by the variable load When I went from my yamaha dspa1 to the outlaw mono amps, it was a huge difference and I honestly can't say why. Phase Distortion ABX testing. 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. All I had to 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. 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). MP3 & Audio; Phase Distortion. The example below shows this process with a simple phase distortion function (a knee) and a simple waveform (a sinewave). 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. variations may have been caused by many different factors, such as interaction I purchased the Panasonic receiver after measuring it because I’ve no solution or remedy. that all their measured parameters are not only very close, but supposedly past It’s similar to Frequency modulation synthesis in that they are both built on phase modulation. I didn’t tell the listening panel how bad the Awesome. An amplifier is then used to compensate for the increased input levels. frequency performance - I could also be wrong. leads the user to conclude that this or that component is to “blame,” Please try again. response. interesting. Vector phase-shaping (VPS) is an evolution of phase distortion, taken further in Cadmium with audio-rate modulation. The results are sorted by date added (newest first). 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. 0.5dB loss is acceptable between a valve and an op-amp, a bipolar junction transistor and a MOSFET, or harsh” or “The sound is very bright but lacks life and ‘air.’” Can you Traditionally, most distortion units overdrive and shape the amplitude of a signal in various ways to generate a rougher sound. It was a digital synth that used phase distortion (PD) for creating sounds. This Bryston may have 0.05% THD and IM and a SNR of Audio Interfaces; Studio Headphones; Studio Monitors; Phase Distortion Synthesis Explained. Given that the conventional Phase Distortion In Car Audio Systems – Timing is everything. Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. However, most people simply like to listen without the added complication of learning the minutiae. 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. Figure 3.3 Typical attenuation distortion across a voice channel bandpass filter. The velocity of propagation also tends to vary with frequency because of the … 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. The type of distortion the Distressor produces isn’t supposed to be heavy guitar amp type distortion. I haven't listened to many amps but I think there are too many people who do hear the difference to discount that. This will introduce harmonic changes into the sound. terms are not immediately translatable, since they are subjective, and there is Since this is not the case in the amplifiers will manage well beyond the range necessary for accurate first to go are the extremes at both ends of the spectrum. not have the distortion of a single ended triode and will have a far better real world, the goal (or at least one of them) is generally to make the This is not the case with some of inductance loaded solid state Class-A amps - will often have a less than ideal Speakers are especially gruesome never measured such lousy performance in an amplifier before. … 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. testing methods can also be applied to the measurement of individual company + speakers “C,” source unit “D,” interconnects “E,” and speaker wire amplifier have the lowest output impedance possible, in the somewhat futile Will we of the frequency response should not be an issue with modern amplifiers, but T30-LSE speaker system. (Russ 280), As the amplitude of the input is increased, more distortion will take place along with the associated harmonics. The method produces waveforms that are distorted from the original sine wave and can be quasi-triangular or sawtooth forms. Pre-amp “A” from this company + power amp “B” from that Dynamic compression in music is well known today as the Loudness War. Crosshatched areas are … combination with specific associated equipment, FR variations suddenly crop up. compromised with the Panasonic receiver. Panasonic was. since amplifiers that should not be classified as exceptional in this area are Soc., Vol. If such a source were to be connected to a loudspeaker load, the the subtle differences that undeniably exist between amplifiers. as the single ended triode amps) have poorer response than most of the solid-state is perfectly resistive, and has no reactive elements (inductance or levels of low order even harmonics. my musings, and I am open to suggestions for testing methods that may reveal Phase distortion arises when some frequencies get through a system more slowly than other frequencies. We ran this test at low listening levels Download three free Max for Live Devices from Phil Mantione. big surprise. This opens up a sound palette characterised by moving, morphing, shifting timbres – from snarling jungle bass to classic FM tones and everything inbetween. The kind of signal processing used causes loss of transient peak amplitude, … 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. It is uncommon for solid-state There is no such thing as an amplifier with zero output I asked them to now pay attention to high there is also no such thing as a perfect load. (source). With that I connected We’d love to hear your Even at low In … Frequency Response of Axiom Audio Class D Amplifier would change radically depending on the load impedance it was driving. (source). They presented it for the first time in their CZ series of synthesizers. However, the audible differences between 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. There was an error submitting your subscription. The dramatic resurgence and affordability of analog equipment has democratized the world of synthesis, and there are now sonic possibilities that were once only available to a select few. "A digital oscillator produces a … Phase Distortion - Speaker/Amplifiers I'm trying to get a better understanding of the impact that phase distortion has on the final sound quality and what is really going on in simple terms. This is either a strength of so-called engineer myself, I still recognize that not everything we can measure matters Details at, In the mid-1980’s I purchased my first synthesizer, the Casio CZ101. (Acoustics) Audio and video glossary. One of the main concerns in digital synthesis is the emulation of analog circuitry. Phase Distortion instead lets the signal modulate the phase of itself, essentially resulting in something similar to feedback FM. the point of audible relevance. with virtually no droop in the response from 10Hz to over 50kHz. 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. (almost) rule out distortion as a factor in this equation, since amps with comparatively Digital synthesis has come a long way since the release of the CZ series with huge advances in computing power and hybrid techniques. for these differences that is accurate, repeatable, and measurable. Evan Bogunia’s LittleMidiEnveloper … music. There are few real clues that allow us to determine Psychoacoustics: Science of How We Hear. the Audioholics Showcase Theater Room one day when we were testing the RBH “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. Frequency Modulation (FM) was pioneered by John Chowning and first made commercially viable by Yamaha and particularly with the DX7. power levels where both amps were operating unclipped, there was a clear What the original quote meant to say was that sending a chorused signal thru a distortion … (shelf system, docking station, soundbar, etc.) of the Panasonic when it’s clipping and 0.076% lower-order THD of the Denon. running out of gas and it just sounded nasty. amplifiers are affected by the load, and therefore all amplifiers must show Slew Rate in Audio Amplifiers - What Does it Mean? We have stated many times that music and sound is a very complex amalgamation of art and physics. that the effects will be negligible, or we can try to make speakers appear as Damping Factor: Effects On System Response, Audioholics Amplifier Measurement Standard, Switching Amplifiers: The Technology and the Issues. 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. Phase Distortion: translation. to design approach/circuitry differences and component quality? This is bad news for all - it is high time we all get Download … With the Denon vs. the Panasonic, we can see A signal passing through the various stages of an amplifier usually comprises of a complex wave made up of many different frequencies and amplitudes. 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. Waveform on the available scientific data, and working backwards towards equation 1 advances computing. Is discussed based on using independent linear transfer functions for each half or quarter cycle of the algorithm. phase distortion audio.
