that's because you are using a soundfile format that uses fixed-point
values (e.g. 16bit WAV or AIFF), and cannot hold values with a magnitude >1.
so either store your values in a "normalized" fashion (so they don't
exceed -1..+1) and rescale them to their actual values on use; or use
floating-point for storing the values ("-bytes 4")
