Below
are some resulting sounds from the source separation algorithm we have
designed, based on a previous melody detection (in Durrieu et al.,
SINGER MELODY EXTRACTION IN POLYPHONIC SIGNALS USING SOURCE SEPARATION
METHODS, see the publications
page), followed by a spectral
Wiener filtering of the original signal. The songs we used are from the
ISMIR 2004 Audio Melody
Extraction Contest database (see the dedicated ismir 2004 website for more
details and
to download the test set and the reference files). We suggest you to
use headphones in order to be able to hear slight differences and
artifacts in the resulting sounds. If you experience any problems with
the flash player, you can also check this alternate page with
direct links to the files.
The parameters for the analysis of MIREX 2004 database songs are:
Some results on a database I got from http://www.ee.columbia.edu/~graham/mirex_melody/, which seems to be the files "competitors" for the MIREX 2005 Melody Extraction Task could use to tune their algorithms. The parameters are almost the same as before, except that the hopsize for the analysis windows is equal to 10ms (441 samples) to fit the given groundtruth.
... and below another example showing the possible use of our model for other instruments, in excerpts of take five (being a saxophonist, this example was compulsory for me!):
