This is my Audio Midi Setup. I changed the format to 48000.0hz from 44100,0, but my recording still sound distorted.
I have a motu v4hd but I think that might be overkill for what I am doing, can you recommend an inexpensive external A/D?
And do you notice anything wrong with the Audio Midi Setup?
Normally you'd like your audio recorded as 48khz /16 bit for use with video (in AIFF format).
If you are recording into the MacPro, why not use the Motu?
If for some reason that is impractical, there are a number of small, very portable 1, 2 or 4 channel A/D converters on the market.
