Sonic Annotator

[Pradeepiit]

I am using Sonic Annotator to extract pitch from wav files using pYIN method.

sonic-annotator -s vamp:pyin:pyin:smoothedpitchtrack > test.n3
sonic-annotator -t test.n3 /<filename> -w csv --csv-stdout > t.txt

I tried changing the vamp:step_size and vamp:block_size in test.n3 RDF file and execute the command. But it fails, without providing any errors or warnings.

Hi there --
When you say that it "fails", do you mean that it doesn't produce any results, or that the results are not what you expect? or do you mean something else?

It should certainly be possible to do this with the pYIN plugin; the step and block size are apparently intended in the code to be adjustable. (Some plugins will refuse to initialise at all if you try to change the step or block size, but pYIN doesn't seem to be one of them.) I tried this just now, changing step to 512 and block to 1024, and it certainly produced some results, but I don't want to take time to investigate at the moment until I know what I'm looking for!

Thanks!
