-b <number>, --bits <number>

Set the output (individual) sample format. The number takes one of the following values:

1: 16-bit PCM data (default).
2: 24-bit PCM data.
3: 32-bit PCM data.
4: 32-bit floating-point data.
5: 64-bit floating-point data.

-d , --downmix

2: Low Complexity (LC) object type (default).
4: Long Term Prediction (LTP) object type.
23: Low Delay (LD) object type.

-o <filename>, --outfile <number>

Sets the filename for processing output.

-q , --quiet
