[SoX-users] Converting a wav file to 20-bit depth

[R R <el...@li...>]

Hello sox experts,



		I have a .wav file with a 32-bit depth which I need to convert to 20-bit.
I tried the following:

sox input.wav -b 20 output.wav

Where input.wav is a 24-bit depth file. But I get the following warning:

"sox WARN formats: wav can't encode to 20-bit"

I thought 20-bit depth format was simply 24-bit data with the LSBs padded to 0. Is this correct?
Or sox doesn't support 20-bit conversion? Or the wav format itself doesn't support 20-bit?

If not, suggestions on any other methods/tools are welcome.

Thanks,
