Hey, I am creating a program that I will alter your voice or add an effect to your voice. I have the recording an the playback working, but the issue is apply the effects or altering the audio file. I currently have sound pool setup to playback because it lets me speedup an slow down the playback but thats the only "Effect" I can figure-out how to do. I would like to alter stuff like pitch frequency etc, I would create the effects myself but I first need to have access to altering the audio. I also read that Android does not support the Java Sound API so does this mean that its impossible to make my app on android?

Thanks
Adam
