Sound Effects? Mixer

Ok right I have a voice recorder which records whatever the user plays, says etc

I开发者_开发问答s there anyway where i can have effects such as 'slow motion voice' or just like changing the sound effects. Or the 'bass' drops or something

So like a Mixer.

Consider looking into BASS for your audio library. You can use it with many languages. It has sample code for some of the functionality you are looking for, and is a good way to get started.
