Re: Harmonic Analysis on f0-Curve

[Amit Gal <hobbit@xxxxxxxxxxxxxxxxxxxxx>]

Hello,

unfortunately, I'm unaware of such a software at the moment. I looked for
one too sometime ago, and ended up using SFS and an expensive speech analysis
software that is installed in my department's lab.
however, I'm now supervising a team of last year CS students that build a
muicologically oriented audio analysis software as their final project.
they are now gathering requirements and features that the software should be
able to perform. I, of course, gave them some basic requirements and further
features I needed in the past, but they are open to hear any further needs
and features that might make the software more useful. again, the orientation is
musicological - that is, extraction of musical features from audio signal
that will enable analysis of performances.

the project is divided to two parts. the main one is the analysis of
monophonic performances, and another branch is the analysis of polyphonic
signals which is much more complex, and we are not aiming to implement only a
reduced set of features to this branch because of that complexity.

i join the request of hermann: if you know of any musicologically oriented
performance analysis software, I would very much like to know more about it.
however, if you don't - please feel free to share what do you think such
software should be able to do.

the students' intention is to release the software as an open source
freeware - hopefully by the end of the academic year.

thanks,

amit gal.
