Usage

AudioMixer provides multiple AudioMixer implementations to choose from.

• BackgroundSourceDataLineAudioMixer: Easiest to use implementation for realtime audio mixing. It mixes audio in the background and sends it to a SourceDataLine.
• SourceDataLineAudioMixer: Similar to BackgroundSourceDataLineAudioMixer but you have to call mixSlice manually. This allows you to mix audio in sync with the rest of your application.
• AudioMixer: Base mixer class. Intended for rendering audio to a file.

After creating an AudioMixer instance you can play Sound instances with it using the playSound method.

Examples

Examples can be found in the src/test directory.
