There were several applicants who contacted me and i told all to
add themselfs to
(same as previous years)
the page is still empty so iam not sure we have an applicant

its probably better if i add it but you can post a suggested wiki
marked up text here and ill add it to the page if it looks ok
... my lazyness is limitless

also with a project like this its important to carefuly test the
fingerprinting to ensure degraded songs can be quickly and reliably
be matched up in a large set of reference fingerprints/songs

and that changes done during the project do improve this.
It should not be implemented and after that tested that would be bad
the earlier there is something that can be tested an compared against
competing solutions the better and easier it would be to tune things
and easily try modifications ...

that "module" can be a audio->video libavfilter
am i correct that with peaks you mean peaks in a frequency/time 2d
array ?
