How to Build a Spectrum Analyzer for Your Audio Player

I've chosen to include this in this tutorial briefly because I get asked this question so often, "How can I use the properties of a sound object to create a spectrum analyzer?" Well, there is good news and there is bad news. The bad news is that sound object properties do not contain the data needed to represent the audio spectrum for animation purposes (like you see with players like WinAmp or Windows Media Player). The good news is that there is an easy way to do this otherwise. Since this is outside of the scope of this tutorial, I will not cover it here, but you can click the link below to view a full tutorial on this.

The following player illustrates fast forwarding, reversing and pausing streaming sound while animating the audio spectrum using data gleaned from the MP3 file using SwiftMP3. This data can then be used as values for animation. If you have questions regarding this, see my tutorial on how to build an audio player that has a spectrum analyzer animation.
