I want to separate a single track of voice and music into 2 components - narrative and poetry - so they can be played side-by-side and each component can be analyzed for research. And I was advised to try this in Virta.
The narrative part would use the "pitch detector" to recognize the fundamental pitch (which I would save as a separate file). So where is the "pitch detector" in Vitra, and how do I turn it on?
Then the "pitch shifter" could be used to undo this - which would give me one camparison. So where is the "pitch shifter" and how do I use that to remove the "pitch detector" effect?
Also I could add another instance of Virta to output a sine wave or something else at the detected pitch. So again, how would I do that?
With answers to these 3 questions I could make the filters myself and do my initial research for further study.
Thanks for any suggestions you may have. I would use Ableton Live 10 (64 bit) with macos Catalina 10.15 07 and a Motu Ultralight 3 Hybrid with the latest drivers, on a 16" Macbook Pro.
I realize this may sound complicated - but I don't think it has to be. I just don't know how to do it myself :) Thanks for any help you can offer.
FYI: I now own Alto and Virta, if that helps... Randy
Just saying, this is huge if i/we can pull it off... :)
Aside from art - which is always there - we have the notion of a global language of the senses. That's the 'big' idea. But the small idea is just as important - research those sounds which change a talk, song, sound (even in improvisation) into a piece of poetry which communicates through the subconscious to the conscious with vibes that we can hear and truth which resonates.
Welcome aboard! Virta's pitch shifter is in the DELAY module. You'll just be using the pitch aspect of the module and not the delay. The source signal to "undo" the pitch of the audio input will come from the pitch output of the AUDIO module.
Looking at the manual, hopefully you can see how to track the pitch of an input signal, and send it through a patch cord to the audio module. Setting the amount of offset in the input attenuation dial is the only tricky part. You'll want a negative setting that is the inverse of the positive setting that tracks the pitch correctly. This may be easier to hear with an oscillator as the input to the delay than the input signal. For that matter, you could use an oscillator from outside Virta as the input to the AUDIO module, just to start with something very easy to track.
Virta's pitch tracker is designed for use with voice, so hopefully it will work well for you in this application. I think Virta is unique in being able to do something like this without being a much more complex and open-ended tool like Supercollider or Max/MSP.
Thank you. I just saw this now - as I'm about to start working... Happy Thanksgiving.
