We present in this paper the recent development of an online platform for musicians, researchers and an open community of enthusiasts of audio and music with a view to build a public database of music recordings from a wide variety of styles and different cultures. The data generated and collected will primarily be audio data, coming from various sources, including field recordings, existing datasets, and users’ collaboration. The platform aims at gathering a distributed music crowdsourcing database collection where each music piece is built from asynchronous recordings of different tracks at remote sites. The complete tool and databases generated will be openly distributed for research purposes.
