Minecraft Mod - AudioMod Beta 1.7_01
This mod allows Minecraft to play (in addition to ogg, wav, and mus files), xm, s3m, and mod files. The only readily available feature of this mod is the ability to add new music, however, it adds support for modders to add new recordings and sounds.
There is a slight increase in load time when using this mod. Using this, you can also use custom sounds, alongside the originals. Custom music and sound goes into the resources folder, music in mod/music. Custom sounds go into mod/sound.
