1. Buffered raw audio recorder/player The rawrec/rawplay utilities provide a simple way to record or play back raw audio data. Options exist to control the timing of the run, add silent guard time, jump into data files, set DSP parameters, and control buffer size and latency. rawrec should be particularly useful for scripting applications that need to deal with raw audio data. Compared to bplay, rawrec tries to do less (it only handles raw audio) and does it more correctly (all the options work right for raw audio. I think :). rawrec can work to or from standard io, so if you also get the sox program, you will be able to record and play a wide variety of sound formats. You will need a mixer program, such as aumix. From Debian 3.0r0 APT
