BASS is an audio library for use in Windows and Mac OSX software. Its purpose is to provide developers with the most powerful and efficient (yet easy to use), sample, stream (MP3, MP2, MP1, OGG, WAV, AIFF, custom generated, and more via add-ons), MOD music (XM, IT, S3M, MOD, MTM, UMX), MO3 music (MP3/OGG compressed MODs), and recording functions. All in a tiny DLL, under 100KB* in size.

On Windows, BASS requires DirectX 3 or above for output, and takes advantage of DirectSound and DirectSound3D hardware accelerated drivers, when available. On OSX, BASS uses CoreAudio for output, and OSX 10.3 or above is recommended. Both PowerPC and Intel Macs are supported.

C/C++, Delphi, Visual Basic and MASM APIs are provided, with several examples to get you started. .Net and other APIs are also available.

Am incercat BASS si m-i sa parut reusit, chiar foarte bun, cu un minus la capitolul "ease of use". Acum vreau sa ma uit peste OpenAL si sa fac o comparatie de performanta (am auzit ca BASS e mai lent, dar sunt doar rumours, probabil nefondate).
Oricum, il recomand oricui are nevoie de un API compact, stabil si performant.

Pacat ca nu e si pentru Linux... cat despre faza cu 100kb, pai si FMOD tot cam atata e, si majoritatea.
