I'd like to start developing some iOS apps involving audio analysis. I've been reading some Apple's documentation such as Audio Session Programming Guide, but I still need a starting point to audio analysis. I would like to know how could I do things like, for example, in Shazam app: how could you "compare" two audio files/streams? Or like several other apps do: how could you detect the rhythm of an audio file or stream to show, let's say, an animation moving at the same rhythm?

I need some guidence, I know I'm missing some audio analysis basics and I'd appreciate some starting point to learn them and how to apply them in iOS apps.

Thanks in advance

  • For Shazam-type matching, google MFCCs and audio fingerprinting. For beat detection, check the MIREX/music-ir web site for research papers on audio beat tracking. – hotpaw2 Apr 01 '15 at 01:35
