This database was produced within the CHIL Project (Computers in the Human Interaction Loop), in the framework of an Integrated Project (IP 506909) under the European Commission's Sixth Framework Programme. It contains a set of isolated acoustic events that occur in a meeting room environment and that were recorded for the CHIL Acoustic Event Detection (AED) task. The recorded sounds do not have temporal overlapping. The database can be used as training material for AED technologies as well as for testing AED algorithms in quiet environments without temporal sound overlapping.

The UPC database of isolated acoustic events was recorded in 2005 using 84 microphones; namely, Mark III (array of 64 microphones), three T-shape clusters (4 mics per cluster), 4 tabletop directional, and 4 omni-directional microphones. The database consists of 13 semantic classes plus “unknown”.

Approximately 60 sounds per each of the sound classes were recorded as shown in the following Table. Ten people participated in recordings: 5 men and 5 women. There are 3 sessions per each participant. At each session, the participant took a different place in the room out of 7 fixed different positions.
