Reading datas from sound files

Hello,

I'd like to know if there's a way to read datas of a sound file like Trapcode's Sound Keys does it for After Effect.

Thanks.

What do you mean exactly?, unity not have a lot of things about the changing a sound but it has a few things about changing the sound like: pitch, volume, etc..(all the basic things a sound needs) if you want to know more about the things that unity has about the audio there is: http://unity3d.com/support/documentation/ScriptReference/AudioClip.html, http://unity3d.com/support/documentation/ScriptReference/AudioImporter.html, http://unity3d.com/support/documentation/ScriptReference/AudioSource.html, and others you may find in the http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.html#Overridable%20Functions0

Take a look at this question, where you can get the intensity of a range of frequencies.
