We present a system for acoustic scene classification, which is the task to classify an environment based on audio recordings. First, we describe a strong low-complexity baseline system using a compact feature set. Second, this system is improved with a novel class of audio features, which exploit t…
Most of multichannel sound source Direction Of Arrival (DOA) estimation algorithms suffer from spatial aliasing problems. The phase differences between a pair of microphones are wrapped beyond the spatial aliasing frequency. A common solution is to adjust the distance between the microphones to obta…
Methods are available for simultaneous localization of multiple (unknown) audio sources using microphone arrays. Typical algorithms aim at localizing all active sources. They moreover require that the number of sources is known and is less than or equal the number of microphones. This constraint can…
