GoSTSound plays YM music files using the ST-Sound Library by Arnaud Carré.
The minimal Go wrapper uses cgo to call out to the ST-Sound libary to calculate the PCM sound data.
To play the music GoSTSound uses the excellent Go library Oto (https://github.com/hajimehoshi/oto).
The original ST-Sound library written in C/C++ is distributed under BSD license. A copy of the original zip archive, StSound_1_43.zip, is included in this repo.
