Medley-solos-DB: a cross-collection dataset for musical instrument recognition

Medley-solos-DB ============= Version 1.2 March 2019.     Created By -------------- Vincent Lostanlen (1), Carmine-Emanuele Cella (2), Rachel Bittner (3), Slim Essid (4). (1): New York University (2): UC Berkeley (3): Spotify, Inc. (4): Télécom ParisTech   Description ---------------   Medley-solos-DB is a cross-collection dataset for automatic musical instrument recognition in solo recordings. It consists of a training set of 3-second audio clips, which are extracted from the MedleyDB dataset of Bittner et al. (ISMIR 2014) as well as a test set set of 3-second clips, which are extracted from the solosDB dataset of Essid et al. (IEEE TASLP 2009). Each of these clips contains a single instrument among a taxonomy of eight: clarinet, distorted electric guitar, female singer, flute, piano, tenor saxophone, trumpet, and violin. The Medley-solos-DB dataset is the dataset that is used in the benchmarks of musical instrument recognition in the publications of Lostanlen and Cella (ISMIR 2016) and Andén et al. (IEEE TSP 2019).   [1] V. Lostanlen, C.E. Cella. Deep convolutional networks on the pitch spiral for musical instrument recognition.

Every audio clip has a fixed duration of 2972 milliseconds, that is, 65536 discrete-time samples. Every audio file has a name of the form: Medley-solos-DB_SUBSET-INSTRUMENTID_UUID.wav   For example: Medley-solos-DB_test-0_0a282672-c22c-59ff-faaa-ff9eb73fc8e6.wav corresponds to the snippet whose universally unique identifier (UUID) is 0a282672-c22c-59ff-faaa-ff9eb73fc8e6, contains clarinet sounds (clarinet has instrument id equal to 0), and belongs to the test set.   Metadata Files ------------------- The Medley-solos-DB_metadata is a CSV file containing 21572 rows (one for each audio clip) and five columns: 1. subset: either "training", "validation", or "test" 2. instrument: tag in Medley-DB taxonomy, such as "clarinet", "distorted electric guitar", etc. 3. instrument id: integer from 0 to 7. There is a one-to-one between "instrument" (string format) and "instrument id" (integer). We provide both for convenience. 4. song id: integer from 0 to 226. The track and artist names are anonymized. 5. UUID4: universally unique identifier. Assigned and random, and different for every row.   The list of instrument classes is: 0. clarinet 1. distorted electric guitar 2. female singer 3. flute 4. piano 5. tenor saxophone 6. trumpet 7. violin   Please acknowledge Medley-solos-DB in academic research --------------------------------------------------------------------------------- When Medley-solos-DB is used for academic research, we would highly appreciate it if  scientific publications of works partly based on this dataset cite the following publication: V.
