BASS is an audio library for use in Windows software. Purpose of the software is to provide developers with the stream (MP3, MP2, MP1, OGG, WAV, and custom generated via add-ons), MOD music (XM, IT, S3M, MOD, MTM, UMX), MO3 music (MP3/OGG compressed MODs), and recording functions.
BASS requires DirectX 3 or above, and takes advantage of DirectSound and DirectSound3D hardware accelerated drivers, and MMX CPUs. But it is also functional without these performance enhancers. C/C++, Visual Basic, Delphi, and MASM APIs are provided, with several examples to get you started. Other APIs are also available.
