It includes filters that perform time compression/expansion and rate transposition. In tandem, these filters can perform pitch-shifting.\n\nUsage\n=====\n\n    var source:Sound = …;\n    var output:Sound = new Sound();\n\n    var soundTouch:SoundTouch = new SoundTouch();\n    soundTouch.pitchSemitones = -6;\n\n    var filter:SimpleFilter = new SimpleFilter(sound, soundTouch);\n    output.addEventListener(SampleDataEvent.SAMPLE_DATA, filter.handleSampleData);\n\n    output.play();\n\nFor details on using the SoundTouch, Stretch, or RateTransposer classes, look in SimpleFilter and FilterSupport.\n\nRoadmap\n=======\n\nThe 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.\n\nSupport\n=======\n\nFor issues using SoundTouch AS3, open a ticket at the [GitHub project][2], or contact [ryan@ryanberdeen.com][3].\n\nLicense\n=======\n\nSoundTouch AS3 audio processing library\n\nCopyright © Olli Parviainen 2001-2009  \nCopyright © Ryan Berdeen 2009\n\nThis library is free software; you can redistribute it and/or\nmodify it under the terms of the GNU Lesser General Public\nLicense as published by the Free Software Foundation; either\nversion 2.1 of the License, or (at your option) any later version.\n\nThis library is distributed in the hope that it will be useful,\nbut WITHOUT ANY WARRANTY; without even the implied warranty of\nMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
