Splitting audio into frequency bands and colours?
Feb 26 2012 | 7:03 pm
Does anyone know if its possible to split a normal audio track .wav into separate frequencies for example linkin park, and create a patch that picks out the frequencies in realtime, a bit like scope~ object but having multiple objects to visually show the active frequencies iered for 0 to 100hz, orange 100hz to 1000hz etc? any one know if this is possible or has a patch or link to one?
i know theres a sonogram but i wanted a sonogram in waveform rather than just a block with colours all over it...
many thanks

- Feb 26 2012 | 7:36 pmwhat about having some bandpass filters going into scope~s if i understand your question?
- Feb 26 2012 | 7:40 pmHi woyteg,i've tried that, just going through the filters doesn't seem to really work.... its not accurate enough i dont think :/ i'm using jitter as well to try and get a much smoother signal...

- Feb 26 2012 | 9:50 pmWhen you say it's not accurate enough do you mean the filter slopes are not powerful enough? If so you could try using the cross~ object or perhaps some fft based filtering?Your project looks interesting, what is it for?
