[PD] spectrum analyzer ?

[Andrey Savitsky]

Hello pd-list!
i'd like to construct an oscilliscope with spectrum analyzer.
Could you drop any idea how can i do this one.
Or by another words: how to detach any frequency from audio input?
Are there any special objects or abstractions?

thanks in advance.
