Re: [music-dsp] Who uses YIN or pYIN for pitch detection?
Pyin seems nice, I never tasted it before ! Yeah I use YIN, I made a sacred way searching and writing Pitch Tracking algorithm to works with Keith Lent Pitch Shifting, I have coded the basic steps of YIN in matlab, but for me or my implementation not works so well like AMDF or some improved ACF... BTW the author of paper seems that put the source code online here https://code.soundsoftware.ac.uk/attachments/download/1458/pyin-v1.1.tar.gz Regards, Eder de Souza On Thu, Mar 7, 2019 at 1:47 AM Ethan Duni wrote: > Looks like they use the Viterbi algorithm to get the pitch tracks. > > On Mar 6, 2019, at 6:59 PM, Jay wrote: > > > Looks like there's a link to a python implementation on this topics page, > might provide some insights: > https://github.com/topics/pitch-tracking > > > > > > > > > On Wed, Mar 6, 2019 at 6:44 PM robert bristow-johnson < > r...@audioimagination.com> wrote: > >> >> >> Hay, any peeps around here that use YIN? or pYIN? >> >> Some of you who hang around the DSP Stack Exchange might know that I am >> unimpressed with YIN, namely that I don't think there is anything novel >> about it (w.r.t.

Looks like they use the Viterbi algorithm to get the pitch tracks. > On Mar 6, 2019, at 6:59 PM, Jay wrote: > > > Looks like there's a link to a python implementation on this topics page, > might provide some insights: > https://github.com/topics/pitch-tracking > > > > > > > > >> On Wed, Mar 6, 2019 at 6:44 PM robert bristow-johnson >> wrote: >> >> >> Hay, any peeps around here that use YIN? or pYIN? >> >> Some of you who hang around the DSP Stack Exchange might know that I am >> unimpressed with YIN, namely that I don't think there is anything novel >> about it (w.r.t.

Looks like there's a link to a python implementation on this topics page, might provide some insights: https://github.com/topics/pitch-tracking On Wed, Mar 6, 2019 at 6:44 PM robert bristow-johnson < r...@audioimagination.com> wrote: > > > Hay, any peeps around here that use YIN? or pYIN? > > Some of you who hang around the DSP Stack Exchange might know that I am > unimpressed with YIN, namely that I don't think there is anything novel > about it (w.r.t.
