Audio Comparion in iPhone 4g

I want to ask that, Is it possible to compare two audio files in iphone? Does objective-c have any framework for audio comparison?

please hel开发者_如何学运维p me out on this, I want to compare different audio files with one another.


In Iphone no framework is available to compare the two audio files .
You should take the two array of sample data and compare as integer or float value. and set the threshold value (if 70 % ) frames matched so voice is same .
