Community resources

The MTG contributes to create and maintain active communities and resources around sound, music, and technology. Projects like Freesound bring together a community of people interested in sound, that grows and gets more active year after year. Currently, it supports more than 6 million registered users. Other examples are Dunya, which is a collection of music corpora, or AcousticBrainz, with which we crowdsource acoustic information of music tracks and makes it openly available, or smcnetwork, which supports a number of resources for the sound and music computing research community.


Freesound aims to create a huge collaborative database of audio snippets, samples, recordings, bleeps, ... released under Creative Commons licenses that allow their reuse. Freesound provides new and interesting ways of accessing these samples, allowing users to:

  • browse the sounds in new ways using keywords, a "sounds-like" type of browsing and more
  • upload and download sounds to and from the database, under the same creative commons license
  • interact with fellow sound-artists!

We also aim to create an open database of sounds that can also be used for scientific research.



he AcousticBrainz project aims to crowd source acoustic information for all music in the world and to make it available to the public. This acoustic information describes the acoustic characteristics of music and includes low-level spectral information and information for genres, moods, keys, scales and much more. The goal of AcousticBrainz is to provide music technology researchers and open source hackers with a massive database of information about music.



Dunya comprises the music corpora and related software tools that have been developed as part of the CompMusic project. These corpora have been created with the aim of studying particular music traditions and they include audio recordings plus complementary information that describes the recordings. Each corpus has specific characteristics and the developed software tools allow to process the available information in order to study and explore the characteristics of each musical repertoire.


SMC Network

The portal is hosted by the MTG as a service to the whole SMC community.

This initiative was started as an outcome of the S2S² EU project and it is now under the supervision of the SMC board.
