Below are some resulting sounds from the source separation algorithm we have designed, based on a previous melody detection, 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. To go back to the page with the flash player, click here.
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!):
