开源代码，元音的滤波和人工合成，delphi开发，VST插件,Hello and welcome to Tobybear VowelSynth/VowelFilter!

This is a simple VST plugin (PC only) by Tobybear (www.tobybear.de)
using the formant filter algorithm from Alex (alex@smartelectronix.com),
hence it is called another "Tobybear VS SmartElectronix" open source
plugin thing. The full Delphi source code is included as this is mainly
just a simple example to show how you could implement some DSP related
things in Delphi. This plugin is available on Bram s truly excellent DSP source
code page www.musicdsp.org
