Re: [SoX-users] Nondeterministic behavior with pipes

[Charles W F. <cha...@sh...>]

While I'm here though, here's a simple version of my other problem:

Here, a.wav is a 16k, 16bit file, and the output should be in the same
16x16 format:

sox -m -v 1 -t sox "|sox a.wav -p pad 0s trim 0 5s"      -v 0.5 -t sox
"|sox a.wav -p pad 1s trim 0 5s"  out.wav

My problem is that the only way I know to make the pipes work is to use "-t
sox", (-p gives errors), and this is forcing a conversion to 32bit.
Anyone know how to have 16bits pipe all the way through this, whilst still
allowing the trim and pad to work ?   Somehow I think I need to tell the
subprocesses to output in that format, and also have it picked up by the
outer process?
