Struggling with fzero~…

Struggling with fzero~…

Hi,
I’m trying to immigrate out of gbr.yin~, my trusted pitchtracker and move on with my new life with fzero~. (since now fiddle~ seems defunct)

I put all kinds of filters to fit me (violin) but still can’t get it to work well as gbr.yin~. I wouldn’t think of using fzero~ if it wasn’t for the gabor objects (IRCAM) problem in M4L; it won’t work, and FTM is also a pain for standalone.

If anyone has any suggestion I greatly appreciate… Someone said something about using zl stream, zl median but I don’t know how. It sounds like those maybe what I need…

ps. All the stuff I have under fzero~ – change, round, speedlim etc. etc. is for the violin…I use it also with gbr.yin~

ps. BTW this is my gbr.yin~ patch made for me at IRCAM… (by Norbert Schnell) I have been using this for a few years now in all my concerts.

What is happening with fzero~ that isn’t working for you? I’d be glad to help, but I’m not sure where to start.

Thanks so much, going to private convo. It’s the general behavior, erratic output and mistakes…

Why go to private convo? One of the advantages of an online community is that you might find someone who has already answered your question. You could save a future user the trouble by keeping the conversation, along with any solutions, public.

Yes sorry—Michael kindly emailed me to help—I just sent him this, side by side comparison. I made a simple violin phrase to load in so you can see exactly what the problem is…

OK here it is—please load this violin soundfile to see the result.
Here it is in the dropbox, soundfile named 10-11.aif (I can’t get rid of the error message. The file was too big to upload in this forum)

I’m still working on this, but taking the median helps. Also, normalizing the input audio made a noticeable difference. The levels on the file above are really low.

Thanks so much! I understand my level is low, but using gbr I didn’t have a problem…

ps. And those who use FTM you can see the new comparison:

Since I’m pressed with projects I decided to use yin~ to replace gbr.yin~ since yin~ works in M4L and Standalone without hassle. Still cannot use fzero~ for performance…
