I have enjoyed this thread, but I wanted to bring up four points not addressed by the debate. 1) Surround sound: If you have 5:1 surround sound, somehow that gets encoded into the same sample rate as 2 channel sound, and there must be some corresponding quality loss overall. So it strikes me that if you want higher fidelity surround, the end output needs to have more bits than nyquist dictates. 2) Telephony (see asterisk.org or freeswitch.org) depends on 8khz clock for just about everything. 48khz and 96khz and for that matter 192khz are even multiples of that. It would be nice to see everybody standardize on *something* superior to 44khz that made telephony just another audio app. 3) As I noted in an earlier email, recording sources at 96k requires a great deal more fussyness in the studio if you intended to play it back at 96. It wasn't just the sources however. Since there was no "0", no true silence, recorded from any of my sources - Sortcuts taken by the software in all the additional elements in the processing chain amplified the background noise significantly - I remember a particular reverb and phaser combo was downright annoying at 96... In short has anybody built a ladspa noise gate that works well at 96? 4) Why are we producing sound just for humans? Cats and dogs can hear better than we do... and hey, just as much as I loved having records that drove my mom away when I was younger... I'd love to have a record today that drove the gophers and squirrels away. :) On 1/28/06, Ismael Valladolid Torres <ivalladt@xxxxxxxxxxx> wrote: > Hans Fugal escribe: > > I'm no expert of all this, but I am a student of it.
