SoundTouch AS3
==============
An ActionScript 3 port of the [SoundTouch][1] audio processing library.
SoundTouch AS3 allows realtime processing of audio in Flash 10. It includes filters that perform time compression/expansion and rate transposition. In tandem, these filters can perform pitch-shifting.
Usage
=====
var source:Sound = …;
var output:Sound = new Sound();
var soundTouch:SoundTouch = new SoundTouch();
soundTouch.pitchSemitones = -6;
var filter:SimpleFilter = new SimpleFilter(sound, soundTouch);
output.addEventListener(SampleDataEvent.SAMPLE_DATA, filter.handleSampleData);
output.play();
For details on using the SoundTouch, Stretch, or RateTransposer classes, look in SimpleFilter and FilterSupport.
Roadmap
=======
The original C++ library includes several features that have not yet been implemented in ActionScript, including a FIR filter, which can be used to prevent aliasing during rate transposition.
Support
=======
