I am developing an application where i use AVAudioRecorder to record & AVAudioPlayer to play audio files.
But what i want to do is after recording the voice , do some speech processing and make it to cartoon voice & play the audio after that.
So is there any library or framework available by which i will convert my recorded audio to some cartoon voice ?
Dirac2 is one commercial iOS library for independent time pitch stretching, which is the effect that some apps use for the funny voices.
Added later:
Apple added the NewTimePitch Audio Unit, now built into iOS, circa 2012.
