Why does the AudioBox AB64 use a 48K sample rate only?
The short answer is: that’s the AES standard. The detailed reason, though, is that there are serious compromises involved in supporting multiple sample rates simultaneously. We must accommodate 48K because it is the standard and the AudioBox AB64 is a professional audio device. ABEdit automatically resamples files recorded at any other sample rate while the file is being sent to the AudioBox AB64 using the freeware resampling program called Sox, which is the best program known for doing this.
