I’m trying to use mubu as an additive synthesizer based on SDIF data provided by SPEAR, and am facing two problems:
1/ the pitches are slightly too high when compared to the original. It definitely reminds me a sample rate problem (44k vs 48k) but everything is set to 44100 Hz: the sound file, SPEAR, the audio driver, etc…
2/ for complex SDIF files (i.e. with a lot of partials), I get random NaNs at the output of mubu.additive~. By random I mean: 1/ they appear only at certain positions/frames of the SDIF files and 2/ the problematic frames change all the time when loading the patch a new time. This problem does not happen for simple SDIF files with a few number of partials
Those two problems are pretty consistent for all the sound files I tried.
Attached to this post are three sound files, the corresponding analysis as provided by SPEAR, and an example patch using Mubu.
I’d be totally delighted for any clue about how to solve this.
All the best,
