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

=======
