Professionally produced music recordings

Introduction

According to many positive requests from the community, we decided to repeat this task.

The task includes the following data:

• Test and development data (test1 and dev1) of professionally produced music recordings task of first community-based Signal Separation Evaluation Campaign (SiSEC 2008).
• Test and development data (test2 and dev2) of SiSEC 2010

Test Data

Download test1.zip (7 MB) (Test data of SiSEC2008 )
Download test2.zip (9 MB) (Test data of SiSEC 2010)
Download test2_full_mix.zip (79 MB) (full-length recordings for SiSEC2010 data)

The data consist of stereo WAV audio files, that can be imported in Matlab using the wavread command. These files are named {test1,test2}__[<author>]-[<song>]___[<snip>]__{mix,full_mix}.wav , where <author> is the author name, <song> is the song name, and <snip> is a shortcut for snip information.

The data include the following mixtures (snips and full-length recordings):

test1

• test1__tamy-que_pena_tanto_faz__snip__mix.wav
• test1__bearlin-roads__snip__mix.wav

test2

• test2__glen_philips-the_spirit_of_shackleton__snip_163_185__mix.wav
• test2__nine_inch_nails-the_good_soldier__snip_104_125__mix.wav
• test2__shannon_hurley-sunrise__snip_62_85__mix.wav

test2_full_mix

• test2__glen_philips-the_spirit_of_shackleton__full_mix.wav
• test2__nine_inch_nails-the_good_soldier__full_mix.wav
• test2__shannon_hurley-sunrise__full_mix.wav

Development Data

Download dev1.zip (22 MB) (Development data of SiSEC 2008)
Download dev2.zip (36 MB) (Development data of SiSEC 2010)
Download dev2_full_mix.zip (75 MB) (full-length recordings for SiSEC2010 data)

The data consist of stereo WAV audio files, that can be imported in Matlab using the wavread command. These files are named {dev1,dev2}__ [ <author> ] - [ <song> ]__[ <snip> ]__ {mix,full_mix,<track>}.wav, where <author> is the author name, <song> is the song name, <snip> is a shortcut for snip information, and <track> is the separated track name (e.g., "vocals", "bass", etc.).

The data include the following mixtures (snips and full-length recordings):

dev1

• dev1__bearlin-roads__snip_85_99__mix.wav
• dev1__tamy-que_pena_tanto_faz__snip_6_19__mix.wav

dev2

• dev2__another_dreamer-the_ones_we_love__snip_69_94__mix.wav
• dev2__fort_minor-remember_the_name__snip_54_78__mix.wav
• dev2__ultimate_nz_tour__snip_43_61__mix.wav

dev2_full_mix

• dev2__another_dreamer-the_ones_we_love__full_mix.wav
• dev2__fort_minor-remember_the_name__full_mix.wav
• dev2__ultimate_nz_tour__full_mix.wav

Separated tracks files (needed for evaluation in dev1 and dev2) are in the corresponding folders named {dev1,dev2}__[<author>]-[<song>]__tracks .

All the former test and development data (test1 and dev1) are from MTG MASS database by M Nxx yy.

All the remixes of newly proposed data (dev2 and test2) are done by Michel Desnoues from Telecom ParisTech .

Tasks

The following should be taken in to account:

• Note that only 20 seconds snips are asked to be separated, and not full-length recordings.
• Some track names below have the following meaning:
  • "vocals" = "a sum of any singing including main vocal, back vocals and singing in the reverb"
  • "drums" = "a sum of any drums including bass drum, hi-hat, snare etc."
  • "bass" = "bass guitar only (i.e., not bass drum)"

Submission

Participants may submit separation results for any above-mentioned tracks of any above (test and development) mixtures.

In addition, each participant is asked to provide basic information about his/her algorithm (e.g. a bibliographical reference) and to declare its average running time, expressed in seconds per test excerpt and per GHz of CPU.

Note that only 20 seconds snips are asked to be separated, and not full-length recordings.

How to submit the separation results will be announced before the end of July, 2011.

The submitted audio files will be made available on a website under the terms of the same license as indicated in the section Licenses above. In other words, any modified version inherit exactly the same license as the original.

Evaluation criteria

The same basic evaluation criteria as for the under-determined speech and music mixtures dataset will be used first so that results are comparable. More precisely, the estimated stereo source signals will be evaluated via the criteria used for the Stereo Audio Source Separation Evaluation Campaign, except that the order of the sources is fixed. These criteria distinguish spatial (or filtering) distortion, interference and artifacts.

• Associated matlab code: bss_eval_images_nosort.m

Additional evaluation will be provided through the perceptual evaluation toolkit PEASS.
