Time-Frequency-Function

Hi everyone! I’m quite a greenhorn using Touchdesigner, but want to use it for a university project. I’d like to distort a text-TOP by a time-frequency representation of the same word. My idea was to use an AudioFileIn with an .m4a file of the spoken word and transform it into a function (x-axis: time, y-axis: Frequency). I attached an example of the type of function I think off: https://www.cs.tut.fi/sgn/arg/intro/basics/snarefft.jpg. If this would be too hard to implement, is there the possibility to do the same thing with the amplitude on the y-axis?

I’m really grateful for all kind of hints, I don’t expect to be shown the whole implementation, just a few tips on how to transform the audio signal!

Hi @marc567,

would the Audio Spectrum CHOP get you a step closer? You could record the spectrum over the duration of the word being spoken with a Trail CHOP. The Audio Spectrum CHOP also let’s you adjust the output length so that the overall number of samples doesn’t get prohibitively large.

Does this help a bit?
Cheers
