I read about.wav file format by googling,all I could figure was that Frames are made of samples(of some defined bit depth) and a wav stereo file has a multiple of something called channels.... The confusion is whether a channel is made up of frames? Do all channels play along when I play some audio file? If a channel is made up of frames,are all channels equal in length(bit wise)? Please answer if someone can,I have to display each channel separately when playing a wav file in waveform
In each frame in wav there are channels. If you have stereo sound, then each frame contains two samples (left and right).
- Do all channels play along when I play some audio file?
Yes, unless you chose to play only one channel. Then samples for second channel are ignored.
- If a channel is made up of frames,are all channels equal in length(bit wise)?
Yes.
