    Hi! I'm working on a patch using music.
    i want to make a visual thing that react specific frequency.
    visual thing is jit.qt.movie
    for example, i want to get frequency data of base sound , melody, and other sound.
    i searched fft~ and cartopol~. so i can see the frequency of music. but i can get number data.
    so how can i use this?(fft~, cartopol~)
    or how can i do this?(getting each frequency data)
    Thank you~!

      If its frequency data you want/need Alex Harkers descriptorsrt~ can give you that data.
      There's other options too sigmund, analyzer, and the older pitch, though I think some of those just spit out midi note numbers (rather than frequency).

      There's also fzero~.
      But as far as I know, all these analyzers are made for monophonic audio only.
      I think it will be difficult to extract information for all the instruments independently.
