I have a heavily "overflowed" WAV file (samples written in float 32-bit format): instead of [-1.0,+1.0], the samples range goes as far as [-5.0,+5.0].
Using SoX to get raw PCM audio samples from WAV file:
sox --bits 32 --channels 1 --encoding floating-point --rate 48000 input.wav output.raw
I get warnings:
sox WARN sox: `input.wav' input clipped 1163400 samples
sox WARN sox: `output.raw' output clipped 605664 samples; decrease volume?
When I look into the output, I see the samples were clipped, and the range is [-1.0,+1.0] now. However, that is not what I want.
I would like to have exactly same output as input, just in different format (RAW instead of WAV). I need to use command line tool for the task. Is there a way to prevent SoX from doing the clipping?
