analyser

Hello!
I am new in MaxMSP and I want to create a patch that is to be used for frequency analysis of an audio file. I want to analyse the file in 8 discrete bands and to be able to change those bands. I know that the “analyser” object will help me but although I have read the help file I don’t know what to do. Could you give me any advise?

It looks to me (after a brief inspection of the [analyzer~] object) that the frequency graph it outputs is just a bark frequency analysis. You might want to check out the ZSA.Descriptors package by EJ ( http://www.e–j.com/?page_id=83 ) – it’s very, very handy for this sort of thing, though it may not give you exactly what you’re looking for.

You’ll likely want to do the FFT tutorials if you haven’t already done them, as you may have to roll your own solution, in which case you are going to need to use [pfft~] and a whole bunch of math.

Hope this helps!
