Hi,
I was curious how Core Audio handles producers with different sample rates,
let's say 44,100 Hz and 48,000 Hz. I guess this may also be a question
about sound cards. My suspicion is that one consumer must have to face
resampling on the way out. If that's the case, I'm curious what the
resampling looks like, and if it has linear phase.
I'm trying to nail down some quirks that might be sample rate related in a
modem library I work on. If there is resampling that occurs, seems my best
bet is to pick a rate that won't incur resampling, whatever that rate might
be? But I'm not sure how I would get that rate.
Sorry for the rambling here :)
-Brian
