BASS audio library

Download: Win32macOSLinuxAndroidiOSVersion: 2.4.16.7

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, WinCE, and ARM Linux platforms.

Main features

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.

Platform:   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 product price limit is €10 in that case. The price 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.
