very good explanation! thank you (i've studied DSP and built things out of wires, I didn't need to look any of it up... but great explanation) if there is info

very good explanation! thank you (i've studied DSP and built things out of wires, I didn't need to look any of it up... but great explanation) if there is information in the signal that is inaudible (tiny freq modulation), that information can be removed and greater compression will be achieved without loss of sound quality. So, perhaps mp3 doesn't do that, and perhaps it doesn't occur with enough frequency (hahaha) to make it worthwhile, but still, preservation is not guaranteed. but TIL what you are talking about, useful, thanks
