Isolated urban sound database

The Isolated urban sound database contains the audio samples used to design urban sound mixtures using SimScene software. This database has already been used to design urban sound mixtures that can be found in Estimation of the road traffic sound levels based on Non-Negative Matrix Factorization dataset [1] and in Realistic urban sound mixture dataset [2] The dataset contains two folders : - 'event' which includes includes 231 brief sound samples considered as salient, with a 1 to 20 seconds duration and classified among 21 sound classes (ringing bell, whistling bird, car horn, passing car, hammer, barking dog, siren, footstep, metallic noise, voice...) - 'background' which includes 162 long duration sounds (~1mn30), whose acoustic properties do not vary in time. This category includes among others, whistling bird, crowd noise, rain, children playing in schoolyard, constant traffic noise ... More details on this sound database can be found in [3] [1] J.-R.
