saugns is my cli parser, player, and WAV file writer for whatever its SAU (Scriptable AUdio) script language evolves into. Currently, it's a flexible tone generation language supporting modulation techniques, but lacking in both some audio quality niceties and enough expressiveness for musical purposes. The program is written in C99.

Back in 2011 I used DragonFly when starting it, though it now builds with a simple make following download on any of the 4 major BSDs, and also on Linux systems with GNU toolchain and libasound2 installed.

It's now 3 years since I revived this old hobby project, though for the most part, there's been little interest in it - but there's not many places where people are generally interested in such stuff. The most interesting aspects here may possibly be the minimalism, *BSD support, and some ISC licensed code in an otherwise LGPL'd program.

(Usually, I don't get any feedback at all on the program or language when posting about it, though it's a tricky niche thing to get any comments, even critical ones, about. Even vague ideas or impressions could be interesting; from how the cli works to how the script syntax looks, I've been vacillating a lot while thinking about experimenting on.)

The audio playback support is for Linux and *BSD (though the NetBSD support is still using OSS). ISC-licensed code for ALSA, OSS, and sndio can be found in the player/audiodev* files. (More could be added for other APIs in the future, though I hope to make it fit keeping it simple and no-configuration.) The Makefile simply checks uname -s to decide what to link with (with OSS as the fallback), currently good enough for "Linux" and the 4 major BSDs.

I only have x86 and x86-64 machines to test on, but other 32-bit and 64-bit little-endian platforms may work without the need for changes.
