RE: Video: The Distortion of Sound...

"'Lossless' is a term used in describing digital compression schemes. CD doesn't use any compression so I think your "so called 'lossless' CD format" comment is a bit off the mark."


If you have 88/24 and you downsample it to 44/16 you have lost data. The original lie was that 44/16 was "perfect sound, forever", when it was well known that it was not. It is true that after throwing away a good portion of music that you can copy the remainder without losing any more. You could say as much of a copy of an MP3. It's "lossless" if you copy the file as is without decoding and reencoding it. That does not mean it is "lossless" with respect to the original music.

"And vinyl throws away far more."

Apart from ticks and pops and a little low frequency noise on a bad TT, vinyl has about the same dynamic range as CD, after allowing for a 7 dB increase in noise for proper dither and for 20 dB of peak vs RMS headroom. The high frequency response on vinyl goes considerably above 22 kHz, assuming one has a high quality recording and a good MC cartridge. In addition, the vinyl mastering process does not need to use steep filters, which are necessary for 44 kHz digital audio, especially recording.
