notes:

The audio files (664 files, size ~1gb) can be downloaded from http://www.beatport.com/ using the bash script:

./audio_dl.sh

To download the files manually use links of the following form: http://geo-samples.beatport.com/lofi/ e.g.: http://geo-samples.beatport.com/lofi/5377710.LOFI.mp3

To convert the audio files to .wav use (bash + sox):

./convert_audio.sh

To retrieve the genre information, the JSON contained within the website was parsed. The tempo annotation was extracted from forum entries of people correcting the bpm values (i.e. manual annotation of tempo). For more information please contact creators.

[2] found some files without tempo. There are:

3041381.LOFI.mp3 3041383.LOFI.mp3 1327052.LOFI.mp3

Their v2 tempo is denoted as 0.0 in tempo and mirex and has no annotation in the JAMS format.

(1): Most of the audio files are 120 seconds long. Exceptions are: name length 906760.LOFI.mp3 62 1327052.LOFI.mp3 70 4416506.LOFI.mp3 80 1855660.LOFI.mp3 119 3419452.LOFI.mp3 119 3577631.LOFI.mp3 119
