WavUtil

From JavierValcarce.Eu

Summary
WavUtil.exe is a command-line utility that performs some operations on audio files like chage sample rate, raw wav / wav raw file format conversion, etc. It is like SoX but capable of a much more small range of operations. It's written in C#.

Usage

Some examples:

$ wavutil -h

Show help

$ wavutil -w --fmt=s08 --fs=8000 <xfile.raw> <yfile.wav>

Read signed 08-bit samples and write a *.wav file with a Fs=8kHz and 32-bit float sample format

$ wavutil -r --fmt=s16 <xfile.wav> <yfile.raw>

Read a *.wav file and writes signed 16-bit samples in a raw file (headerless). The sampling rate information is lost.

$ wavutil -s --P=2 --Q=3 <xfile.wav> <yfile.wav>

The new sample rate is F_y = (2 / 3)F_x
