Reads WAV and AIFF recordings, in mono or stereo, at any sample rate, as one channel of samples from -1 to 1.
A recording with several channels is read as their average. It also writes mono WAV files of 32-bit floats. WAV may hold integers of 8 to 32 bits or floats of 32 or 64 bits; AIFF holds big-endian integers, and AIFF-C also little-endian integers and floats.
