Two-channel noisy recordings of a moving speaker within a limited area


Scenario

The target is a loudspeaker that occurs within a 30x30cm area. The loudspeaker is (always) directed towards two microphones that are 2 meters distant from the center of the area. Details of the scenario are given in the following figure.

Scenario


Development dataset

Download dev16.zip (external link) (14 MB) (Development dataset, 16 kHz, 16 bits)
Download dev44.1.zip (external link) (63 MB) (Development dataset, 44.1 kHz, 24 bits)

For training, the dataset contains noise-free recordings of utterances played by the loudspeaker when it was standing (without movement) in one of 16 fixed positions within the target area. The file names have the format dev_position_<xx>.wav, where <xx> is the index of the position.

Next, there are four recordings during that the loudspeaker was moved over four positions. A video of the first recording is available for illustration here (external link) . The file names have the format dev_<set>_<positions>_{sim,src,noi,mix}.wav, where <set> is the index of the recording (A, B,C, or D), <positions> contains indices of four positions passed during the movement, and {sim,src,noi,mix} denote, respectively, target source images, source signal of the target, noise, and the noisy recording (sim+noi).

Test dataset

Download test16.zip (external link) (3 MB) (Test dataset, 16 kHz, 16 bits)
Download test44.1.zip (external link) (12 MB) (Test dataset, 44.1 kHz, 24 bits)

The dataset contains five noisy recordings of the moving loudspeaker within the area. The file names have the format test_<set>_x_x_x_x_mix.wav, where <set> is the index of the recording (A, B,C, D, or E). Here, the trajectory of the movement is not revealed.

License

All audio files are distributed under the terms different licenses, as listed below for each recodring:

The data were taken from the MTG MASS database (external link) and from the QUASI database (external link).

Tasks

The following should be taken in to account:
  • The participants are encouraged to separate only the snips of songs in case of test1, test2, dev1, and dev2. In case of test3, the participants are encouraged to separate both snips and 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)"


Tracks to separate (test tasks)

test1__tamy-que_pena_tanto_faz__snip__mix.wav
  • vocals, guitar
test1__bearlin-roads__snip__mix.wav
  • vocals, bass, drums, piano
test2__glen_philips-the_spirit_of_shackleton__snip_163_185__mix.wav
  • vocals, drums, bass, other
test2__nine_inch_nails-the_good_soldier__snip_104_125__mix.wav
  • bass, drums, vocals, other
test2__shannon_hurley-sunrise__snip_62_85__mix.wav
  • vocals, drums, bass, piano
test3__jims_big_ego-mix_tape__{snip, full_mix}__mix.wav
  • vocals, drums, bass, other
test3__vieux_farka_toure-ana__{snip, full_mix}__mix
  • vocals, drums, bass, other

Tracks to separate (development tasks)

dev2__another_dreamer-the_ones_we_love__snip_69_94__mix.wav
  • vocals, drums, guitar
dev2__fort_minor-remember_the_name__snip_54_78__mix.wav
  • vocals, drums, bass, claps
dev2__ultimate_nz_tour__snip_43_61__mix.wav
  • vocals, drums, bass

Submission

Participants may submit separation results for any above-mentioned tracks of the 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.

How to submit

Each participant should make his results available online in the form of a tarball called <YourName>_<dataset>.zip.
The included files must be named as follows:
<dataset><author>-<song><snip or full_mix>__<trackname>.wav
where <dataset> is one of the test/test2/dev2, <filename> is a shortcut for the set of source signals, <trackname> is the name of the extracted track. For example, the estimated vocal track for the task file "test2_glen_philips-the_spirit_of_shackleton_snip_163_185_mix.wav" should be named as "test2glen_philips-the_spirit_of_shackletonsnip_163_185__vocals.wav".

Each participant should then send an email to "zbynek.koldovsky (at) tul.cz" and to "onono (at) nii.ac.jp" providing:
  • contact information (name, affiliation)
  • basic information about his/her algorithm, including its average running time (in seconds per test excerpt and per GHz of CPU) and a bibliographical reference if possible
  • the URL of the tarball(s)

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 evaluation will be done through the perceptual evaluation toolkit PEASS v.2.0 (external link).
