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:

标题文字 标题文字 标题文字
Steps Time limit Storage (hard disk) limit
extractor (for database) Totally 72 hours 40KB for every 10 second audio + 250 MB extra overhead (if needed)
extractor (for query) 40 KB for each query clip
matcher N/A

Submissions that exceed these limitations may not receive a result.
