Audiality

Audiality Status

In Development

Although the unnamed predecessor of Audiality has been used in the game Kobo Deluxe for quite some time, it's a project in heavy development. APIs, the scripting language, specifications and even goals are to be considered in flux until the freeze before the 1.0.0 release.

So, if you want a ready-to-use studio synth/sampler or multimedia audio engine, you might want to look elsewhere, unless you're willing to help out, or just like to play with experimental stuff.

Features

Note that this reflects the state of the development version, which may not yet be available for download. Be patient! If it's not released, it's probably because I have dangling wires all over the place, and you wouldn't want to see the mess anyway. ;-)
