Re: [SoX-users] Multiple instances of SOX

It sounds like the process is purely I/O bound, which is typical for
mixing without re-coding.

You can verify that guess pretty quickly by running half of the
processes on your internal hard drive, and half on a working directory
on a USB drive. If I'm right that should speed it up, how much depending
on how fast the USB drive is.
