of digital distortion is that it is not a traditional phase distortion we are talking about, whereby the phase anomalies are related to frequency in a linear way, such as would happen in a cheap equalizer. digital high frequency distortion is more destructive...

the air at different frequencies that produces Doppler distortion in the far field. Yes, a speaker swinging back and forth on a rope will evidence Doppler distortion because the low frequence swing does not couple to the air signifigantly. This means...

was a prominent high frequency distortion generated by the midrange and highs of the music. It didn't sound like clipping distortion or anything like that. It sounded more "digital" in nature - almost like high frequency artifacts introduced by a poorly...

at a low frequency around a fixed position, to be frequency modulated. One would further expect that the instantaneous frequency of the propagating sound would reflect the dynamic low-frequency velocity the source. If so, the waveform of the fm-demodulated...

sine wave, with no spikes or other high frequency hash, and is also locked tight to a frequency standard (unlike the utility power which has the liberty to tweak the frequency when demand is too high). This will ne...

2 (lack of sonics, whatever that means). There were amplifiers designed to have very low THD *at low frequencies* that do not sound good. This is not surprising at all because some of these amps show excessive distortion at high frequencies at high output...

posts by Monte McGuire (among others; sorry for not mentioning all the great posters by name), are the OP275, 2604, and OPA2132. There are other possibilities, but the prices start getting rather high. Any more recent thoughts on the best amps to use?...

pre amps, which is probably why you rarely see it debated. In fact, often casual listening can pick up differences that may exist. One thing I found that is that the differences can be pronounced in the frequency extremes, especially when comparing tubes...

these recordings go on a phone - not for broadcast and not to be played back on high quality audio equipment. Can anyone recommend a mic that might specifically deal with this sibilance problem. I suppose if we spent thousands of dollars on high end mics...

One, is that it's just a aribtrary EQ and has totally different effects depending on the speaker. Second, heavy EQing (making a loudspeaker perform beyond its normal limits) causes high amounts of IMD (high frequency) distortion. It's not "even with the...
