Awave Studio is a multi-purpose audio tool that reads a veritable host of audio carrying file formats from different platforms, synthesizers, trackers, mobile phones... - It can be used in a variety of ways - as a file format converter, as an audio editor, or as a synth instrument editor. It is the swiss army knife for anyone working with digital audio and music.

Here are just a few examples of common tasks:

Convert between different audio and synthesizer file formats.
Buy a sample CD and use Awave Studio to convert it to a format that your own synth understands. Besides a vast array of different synth-formats, it also supports MIDI SDS, and SMDI transfers.
Play MIDI songs that comes with custom instrument banks, or render them to an audio clip using the built in high-quality software synthesizer.
Do audio editing tasks such as resampling, fading in and out, normalizing amplitudes, applying effects, et c.
Use it as an instrument editor for your synthesizer, sound card, or soft-synth / virtual instrument plug.
