View source for 2014:Singing Voice Separation

== Description ==

The singing voice separation task solicits competing entries to blindly separate the singer's voice from pop music recordings. The entries are evaluated using standard metrics (see Evaluation below).

=== Task specific mailing list ===

All discussions take place on the MIREX "EvalFest" list. If you have an question or comment, simply include the task name in the subject heading.

== Data ==

A collection of 100 clips of recorded pop music (vocals plus music) are used to evaluate the singing voice separation algorithms.

Collection statistics:

# Size of collection: 100 clips
# Audio details: 16-bit, mono, 22.05kHz, WAV
# Duration of each clip: 30 seconds

== Evaluation ==

For evaluation we use the Source to Distortion Ratio (SDR) and Sources to Artifact Ratio (SAR), as implemented by [http://bass-db.gforge.inria.fr/bss_eval/ BSS Eval]:

<math>SDR=10\log_{10}\frac{\|s_{target}\|^2}{\|e_{interf}+e_{noise}+e_{artif}\|^2},</math>

<math>SAR=10\log_{10}\frac{\|s_{target}+e_{interf}+e_{noise}\|^2}{\|e_{artif}\|^2}.</math>

We rank the entries according to <math>\frac{SDR+SAR}{2}.</math>

== Submission format ==

Participants are required to submit an entry that takes in a filename (in the form of *.wav) as its only argument. The entries must send their voice-separated outputs to *-voice.wav and *-music.wav, respectively.

== Packaging submissions ==

All submissions should be statically linked to all libraries (the presence of dynamically linked libraries cannot be guarenteed).

All submissions should include a README file including the following the information:
# Command line calling format for all executables and an example formatted set of commands 
# Number of threads/cores used or whether this should be specified on the command line
# Expected memory footprint
# Expected runtime
# Any required environments (and versions), e.g. python, java, bash, matlab.

== Time and hardware limits ==

Due to the potentially high number of particpants in this and other audio tasks, hard limits on the runtime of submissions are specified.

A hard limit of 24 hours will be imposed on runs. Submissions that exceed this runtime may not receive a result.
