BASS

Platform: Win32, OSX

Current version: 2.4.2.3

BASS is an audio library for use in Windows and Mac OSX software. Its purpose is to provide developers with powerful and efficient 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.

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 and FTP servers (inc. Shoutcast, Icecast & Icecast2), with proxy server support and adjustable buffering
	Custom file streaming Stream data from anywhere using any delivery method, with both "push" and "pull" systems
	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 MODs 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
	Custom DSP Apply any effects that you want, in any order you want
	DirectX 8 effects ^{Windows only} Chorus / compressor / distortion / echo / flanger / gargle / parametric eq / reverb, 2 implementation options each with its benefits (including mixing with DSP functions)
	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, with EAX support
	Flexible Small buffers for realtime performance, large buffers for stability, automatic and manual buffer updating, configurable threading
	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
	Small BASS is less than 100KB*, so won't bloat your distribution

Licensing

BASS is free for non-commercial use. If you are a non-commercial entity (eg. an individual) and you are not charging for your product, and the product has no other commercial purpose, then you can use BASS in it for free. Otherwise, you will require one of the following licences.
	Shareware licence: €100 The "shareware" licence allows the usage of BASS in an unlimited number of your shareware products, which must sell for no more than 40 Euros each. If you're an individual (not a corporation) making and selling your own software (and its price is within the limit), this is the licence for you.
	Single Commercial licence: €950 The "single commercial" licence allows the usage of BASS in a single commercial product.
	Unlimited Commercial licence: €2450 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.
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 20% reduction when purchasing a licence for both platforms, eg. the Shareware licences are €160 instead of €200.
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.
