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.
C/C++, Delphi, and Visual Basic APIs are provided, with several examples to get you started. .NET and other APIs are also available.
BASS is also available for the UWP platform, and ARM64 Windows.
Main 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(S) and FTP servers (including 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, CoreAudio, Android media 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, loopback support on Windows, (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, to individual streams or the final output mix - 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, seamless buffer length adjustment, 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
Licensing
BASS is free for non-commercial use. If you are a non-commercial entity (eg. an individual) and you are not making any money from your product (through sales, advertising, etc) then you can use BASS in it for free. Otherwise, one of the following licences will be required.
PurchaseShareware licence: €125
The "shareware" licence allows the usage of BASS in an unlimited number of your shareware ("try before you buy") products, which must sell for no more than €40 each. Non-shareware products are also permitted, but the price limit is €10 in that case. With subscription models, the limit applies to the annual subscription fee. The limit can be raised by purchasing duplicate licences (for the same platform), eg. 2 licences doubles it. If you are an individual (not a corporation) making and selling your own software, this is the licence for you.PurchaseSingle Commercial licence: €950 (iOS or Android: €475)
The "single commercial" licence allows the usage of BASS in one commercial product.PurchaseUnlimited Commercial licence: €3450
The "unlimited commercial" licence allows the usage of BASS in an unlimited number of your commercial products. This licence applies to a single site/location at which products are being developed with BASS.note that all prices are quoted in Euros, but payment can also be made in several other currencies
These licences are on a per-platform basis. There is a 40% reduction on each additional platform (excluding the iOS/Android Single Commercial specials), eg. Win32 and macOS Shareware licences would cost €200 (125+75) instead of €250.
In all cases there are no royalties to pay and you can use future BASS updates without further cost. Reselling/sublicensing is not permitted. Your products must be end-user products, eg. not components used by other products. Please note that these licences only cover your own software, not the publishing of other's software. If you have got any questions, please get in touch.
