Description
This task requires the query by using exact but noisy recordings.
Data
Database
- 10,000 songs (*.wav)
- mono, 44.1 kHz, 16 bit resolution
Query
- 1,264 10-second clips
- mono, 44.1 kHz, 16 bit resolution
- Recorded by variety brand of smartphones, containing noise
Evaluation Procedures
Top-1 hit rate
Submission Format
Participants are required to submit a breakdown version of algorithm. The two parts are:
1. Database Builder
Command format:
builder %file.db.list% %dir_db%
where %file.db.list% is the input list of database audio files named as uniq_key.wav For example:
./AFP/database/00001.wav ./AFP/database/00002.wav ./AFP/database/00003.wav ./AFP/database/00004.wav ...
Output file(s) should be placed into %dir_db%
2. Matcher
Command format:
matcher %dir_db% %file.query.list% %resultFile%
where %dir_db% is the directory for the built database.
%file.query.list% is the input list of query clips, for example:
./AFP/query/q0001.wav ./AFP/query/q0002.wav ./AFP/query/q0003.wav ./AFP/query/q0004.wav ...
The result file gives retrieved result for each query. The format should be:
%main_query_file_name% %main_top_1_candiate_file_name%
For example:
q0001 00204 q0002 08964 q0003 05566 ...
Time and hardware limits
Due to the potentially high number of participants in this and other audio tasks, hard limits on the runtime of submissions are specified. The time/storage limits of different steps are shown in the following table:
| Steps | Time limit | Storage (hard disk) limit |
|---|---|---|
| builder | 5 second for every 10 second audio + 5 minute extra overhead | 40KB for every 10 second audio + 250 MB extra overhead (if needed) |
| matcher | 5 second for every 10 second audio + 5 minute extra overhead | N/A |
Submissions that exceed these limitations may not receive a result.
