I'm a part of a development team working on an audio processing application. We have the silliest problem that's already caused us some trouble coding. We work with stereo audio signals, and when someone says sample (as in 44100 samples per second), it can either mean a mono sample or a stereo pair of samples. People tend to use there interchangeably, and that drives everyone nuts. Is there a standard name for a stereo pair of samples?
I believe "frame" is the term you're looking for - the set of samples from every channel for a given point in time.
