How to convert an audio file from one format to another?
I have an audio file named with such properties:
`BreakingNews.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz`
I wanted to convert it to this format:
`BreakingNews.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 A-law, mono 8000 Hz`
How can I do this?
