This website allows you to search in Freesound and filter using some of the Audio Commons descriptors for music samples developed during the Audio Commons project.
Use the form interface below to set the filters for your query. Filters can be enabled and disabled by clicking on them. Note the circular knobs in the tonality, tempo and pitch filters. Use them to set the minimum confidence of the annotations for the returned results. The higher you set the knob (turn right), the more accurate results you should obtain.
The Audio Commons Audio Extractor is available in this source code repository.
