BASS is an audio library for use in software on several platforms. Its purpose is to provide developers with powerful and efficient sample, stream (MP3, MP2, MP1, OGG, WAV, AIFF, custom generated, and more via OS codecs and add-ons), MOD music (XM, IT, S3M, MOD, MTM, UMX), MO3 music (MP3/OGG compressed MODs), and recording functions. All in a compact DLL that won't bloat your distribution.

BASS is an audio library for use in software on several platforms.

All in a compact DLL that won't bloat your distribution.

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

BASS is also available for the Win64, WinCE, iOS, Android, and ARM Linux platforms.

Features:

  • Samples Support for WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples
  • Sample streams Stream any sample data in 8/16/32 bit, with both "push" and "pull" systems
  • File streams MP3/MP2/MP1/OGG/WAV/AIFF file streaming
  • Internet file streaming Stream data from HTTP and FTP servers (inc. Shoutcast, Icecast & Icecast2), with IDN and proxy server support and adjustable buffering
  • Custom file streaming Stream data from anywhere using any delivery method, with both "push" and "pull" systems
  • OS codecs ACM, Media Foundation and CoreAudio codec support for additional audio formats
  • Multi-channel streaming Support for more than plain stereo, including multi-channel OGG/WAV/AIFF files
  • MOD music Uses the same engine as XMPlay (very accurate, efficient, high quality reproduction), with full support for all effects, filters, stereo samples, DMO effects, etc...
  • MO3 music MOD music with MP3 or OGG compressed samples (vastly reduced file size with virtually identical sound quality), MO3s are created using the MO3 encoder
  • Multiple outputs Simultaneously use multiple soundcards, and move channels between them
  • Recording Flexible recording system, with multiple device support and input selection, (WMA encoding & broadcasting via the add-on, and other formats via BASSenc)
  • Decode without playback Streams and MOD musics can be outputted in any way you want (encoded, written to disk, streamed across a network, etc...)
  • Speaker assignment Assign streams and MOD musics to specific speakers to take advantage of hardware capable of more than plain stereo (up to 4 separate stereo outputs with a 7.1 soundcard)
  • High precision synchronization Synchronize events in your software to the streams and MOD musics, synchronize playback of multiple channels together
  • Effects Chorus / compressor / distortion / echo / flanger / gargle / parametric eq / reverb
  • Custom DSP Apply any effects that you want, in any order you want
  • 32 bit floating-point decoding and processing Floating-point decoding/rendering, DSP/FX, and recording
  • 3D sound Play samples/streams/musics in any 3D position
  • Flexible Small buffers for realtime performance, large buffers for stability, automatic and manual buffer updating, configurable threading, configurable SRC quality
  • Expandable Add-on system for additional format support and effects (C/C++ API available on request), dynamic plugin loading system, access to underlying DirectSound objects
