The Drivers: OSS and ALSA
The original SoX program was abandoned some time ago, but it lives on through its son (http://home.sprynet.com/~cbagwell/sox.html). Primarily, this command line tool is used to convert audio files, and even apply effects along the way. It's also capable of playing and recording, and is often referred to as the Swiss Army Knife of sound tools.
To give Son of Sox a try, go to the Web site and scroll down to the download section. There are a number of binaries available, but the source code is also there. If you grab the source, gunzip and untar it, change into the sox directory, and then start by typing
Once the autoconfiguration routine finishes, type
make; make install
This sequence first compiles the software, and then runs the installation routine for you. Now you can work directly with the sox program.
