OrchideaSOL === Version 2.0, April 2020. Created By --- Carmine-Emanuele Cella (1), Daniele Ghisi (1), Vincent Lostanlen (2), Fabien Lévy (3), Joshua Fineberg (4), Yan Maresz (5) (1): UC Berkeley (2): New York University (3): Columbia University (4): Boston University (5): Conservatoire de Paris Description --- OrchideaSOL is a dataset of 13265 samples, each containing a single musical note from one of 14 different instruments: Bass Tuba French Horn Trombone Trumpet in C Accordion Contrabass Violin Viola Violoncello Bassoon Clarinet in B-flat Flute Oboe Alto Saxophone These sounds were originally recorded at Ircam in Paris (France) between 1996 and 1999, as part of a larger project named Studio On Line (SOL). One asset of OrchideaSOL is that it contains many combinations of mutes and extended playing techniques. The OrchideaSOL audio data can be used for creative purposes insofar at the use complies with the Ircam Forum License. Please visit: https://forum.ircam.fr/legal/contrat-de-licence-forum-ircam/ The OrchideaSOL metadata can be used for creative purposes insofar at the use complies with the Creative Commons Attribution 4.0 International license (see below). OrchideaSOL can be used for education and research purposes. In particular, it can be employed as a dataset for training and/or evaluating music information retrieval (MIR) systems, for tasks such as instrument recognition, playing technique recognition, or fundamental frequency estimation. For this purpose, we provide an official 5-fold split of OrchideaSOL. This split has been carefully balanced in terms of instrumentation, pitch range, and dynamics. For the sake of research reproducibility, we encourage users of OrchideaSOL to adopt this split and report their results in terms of average performance across folds. Data Files --- OrchideaSOL contains 13265 audio clips as WAV files, sampled at 44.1 kHz, with a single channel (mono), at a bit depth of 16. This is equivalent to the audio quality of a compact disc. Audio clips vary in duration between two and ten seconds. Every audio file has a file path of the form: / / / - - - - - .wav where: corresponds to the instrument family: "Brass", "Keyboards" (includes accordion), "Strings", and "Winds" (i.e., woodwinds). is the full name of the instrument. is the type of mute being used, such as "wah", "harmon", "piombo", or "sordina". If there is no mute, this field is absent. is the type of playing technique. is the abbreviation of the
