what he saidegg_ said:Yes
Not because people can hear up there, but because if you're recording at 44.1kHz everything above 22.05kHz is filtered out of the signal (to avoid aliasing) ... and because it's impossible for a real-world filter to pass 100% of the signal at 22.00kHz and 0% at 22.05kHz, the filter rolls off some of your treble (or worse). If you're sampling at 88kHz, you can allow anything up to 44kHz to hit your convertors, so you can build a much simpler filter that filtering at say 30kHz and gradually rolls off to say 42kHz, so none of the audible part of your signal is affected by the filter
dudley said:sample rate is v important to bear in mind.
the protool recordings we did when we started our current record where done at 88hkskkoz.
if you plan to use protools with an mbox, the highest it can get to is 44,000kfskhzzz. sessions recorded at 88 can't be opened by an mbox, and apparently downsampling sounds terrible.
means we've had very protracted gaps between recording sessions, which has been a pain
