2008:Audio Cover Song Identification

2008 AUDIO COVER SONG IDENTIFICATION TASK OVERVIEW

The Audio Cover Song task was a new task for MIREX 2006. It was closely related to the Audio Music Similarity and Retrieval (AMS) task as the cover songs were embedded in the Audio Music Similarity and Retrieval test collection. However, AMS has change its input format this year so Audio Cover Song and AMS will not be interlinked tasks this year.

Task Description

Within the 1000 pieces in the Audio Cover Song database, there are embedded 30 different "cover songs" each represented by 11 different "versions" for a total of 330 audio files (16bit, monophonic, 22.05khz, wav). The "cover songs" represent a variety of genres (e.g., classical, jazz, gospel, rock, folk-rock, etc.) and the variations span a variety of styles and orchestrations.

Using each of these cover song files in turn as as the "seed/query" file, we will examine the returned lists of items for the presence of the other 10 versions of the "seed/query" file. See DPWE's Average Precision comments below in the Evaluation discussion section.

Input Files

The input lists file format will be of the form:

path/to/audio/file/000001.wav
path/to/audio/file/000002.wav
path/to/audio/file/000003.wav
...
path/to/audio/file/00000N.wav

Two input files will be provide:

1. A list of all 1000 test collection files
2. A list of 330 cover song files

Output File

The only output will be a distance matrix file that is 330 rows by 1000 columns in the following format:

Example distance matrix 0.1 (replace this line with your system name)
1    path/to/audio/file/1.wav
2    path/to/audio/file/2.wav
3    path/to/audio/file/3.wav
...
N    path/to/audio/file/N.wav
Q/R    1        2        3        ...        N
1    0.0      1.241    0.2e-4     ...    0.4255934
2    1.241    0.000    0.6264     ...    0.2356447
3    50.2e-4  0.6264   0.0000     ...    0.3800000
...    ...    ...      ...        ...    0.7172300
5    0.42559  0.23567  0.38       ...    0.000

All distances should be zero or positive (0.0+) and should not be infinite or NaN. Values should be separated by a TAB.

Evaluation

We could employ the same measures used in 2006:Audio Cover Song.
