Determination of pitch change in cents of cello note

[absov]

Hello!

Long time ago we were doing one study in which it was necessary to track the changes of pitch of cello notes in cents. We applied the patch, made in PatchWork. It allows us to analyze a sound file with a record note and as a result get a series of numbers representing the pitch of the note changes in cents a certain time interval. It also provides images with microtonal stave notation of these changes.

Unfortunately, we do not have this patch nor PatchWork. Communication with people with whom we were doing this work, also lost.

Dear experts on OpenMusic! Tell me please, in what direction we should think? Are there any ready-made solutions for a similar tasks using OpenMusic? Where to find them? What library to use for this?

I would be grateful for any tips and advice.
I attach a screenshot of the image of the patch, which we used in PatchWork.

Sincerely, Maxim

Hi Maxim.

It looks to me that you should use the as->om function in repmus library (openmusic standard library) and all should go well.
Of course, you will need the sdiffile class (also in standard) to load your anaysis form AudioSculpt.

Thank you very much! Patch works in a general. But there was another problem. Chord-seq displays the note at the beginning only of the partial. How can I make the Chord-seq display the pitch change within an partial with a certain interval of time? May need to somehow break the analysis into segments?

I will try to formulate my question differently. Can I split analysis of the Partial Tracking into segments? Function as->om generates only one note on the one line of the analysis. Can I split analysis on slices that are equal in the time?
