NOTE: For all libraries, you may want to check Un4seen Developments for new DLLs with bugfixes.

BASS (2.2.0.1)

BASS is an audio library for use in Win32 (9x/ME/2K/XP) software. Its purpose is to provide the most powerful and efficient (yet easy to use), sample, stream, MOD music, and recording functions. This library was written by Ian Luck, over at Un4seen Developments. New features include Add-on plugin system, MOD position & syncing in bytes, Support for AIFF files, Floating-point sampling, More options, and More. If you only want to use this library on Linux, and only need to play module formats, check out BassMod below. There are several examples included with the distribution. It can be downloaded here:

BassMod (2.0)

BassMod is a subset of BASS. It provides simple functions for the playback of the module file formats. It's main strength is that it works on Linux, PocketPC, and MacOS, as well. It can be used in demos or anything that needs to play MOD music, but has tight space requirements. You can read the manual online, as well. BassMod can be downloaded from here:
    BassMod Module Library (61 KB; Windows)
NOTE: The Linux version will be available shortly. For the time being, you can download the Linux shared library from Un4seen. It should hopefully work correctly.

BassCD (2.2.0.0)

BassCD is an extension for BASS which provides the ability to read CD Tracks. This supersedes the CD functions that were in the old 1.8 BASS DLL. You can download BassCD from here:

BassEnc (2.2.0.2)

BassEnc is an extension for BASS which allows channels to be encoded using any command-line encoder that accepts input via STDIN. The examples allow you to encode files into MP3 or OGG format. You must download the two encoders from their respective sites (to follow their licenses.) BassEnc can be downloaded from here:
