Shubham,

If you want to have compressed audio in a wav wrapper, try this (but the quality will be bad because it’s compressed)

ffmpeg -i source.wav -b:a 120k -c:a aac output.wav

The “-c:a aac” switch sets the codec to aac (compressed) rather than uncompressed PCM. “-b:a” to set the data rate for the audio, if needed.
