Is a frame a sample?

Question

I'm working with sound files in Java for a homework assignment (dealing with wave files only). I've read a lot of articles and information about wave files and the header and everything the only thing I'm confused with is a frame (For the sound data to be read in/processed/or manipulated).

Can anyone help clarify the concept of a frame to me? I've been reading that Frame is an interchangeable term with Sample. But I'm getting confused between the two or if there is any difference.

Answer 1

A frame contains one sample for each channel in the audio file. For a mono WAV file, a sample will just be one sample in size. For a stereo WAV, each frame will have two samples, one for the left channel and one for the right. Same logic applies for higher number of channels (5.1, etc.)
