Description
Onset Detection Database is an onset detection test database built using a set of real recordings. This database contains some sounds selected from the RWC database and other real recordings. The songs were selected to cover a relatively wide range of instruments and musical genres.
An onset detection evaluation software, which is also available for research purposes has been developed to compare the detected onsets with the groundtruth. The system computes the number of correct detections, false positives and false negatives, considering a 50 ms error margin.
Quality
19 real recordings in wav format (22,050 kHz, mono, 16 bit) and their onset positions in text format.

Features
- wav format: 22,050 kHz, mono, 16 bit.
- text format: each row contains an onset time in seconds.
