Do you know that WAV is interleaved? Currently I'm looking for something

Am I correct assuming 1 sample of stereo frames

times by a rate of 44100 Hz audio sampled data?
Yes. Just to be 100% clear, a
"sample" is a *single* point of data.
In a mono situation: a "frame" refers to the single sample for that channel.
In stereo: a "frame" refers to 2 samples, one for *each* channel.
So the difference between a frame and a sample is that a sample is
literally a single data point, while a frame is a single "data point"
for each channel.
Whereby one sample contains 2 frames.
See
above :)
CHANNELS = 2
buffer_size_per_second = CHANNELS * 44100 * sizeof(signed short);
Yep. The link
below is useful for double checking, and for quick disk
space calculations:

I've written a tutorial on using SndFile to write to disk: perhaps a
useful resource to check / play with:
