title: Audio Data from: Jazz Trio Database

description: The Jazz Trio Database is a dataset composed of about 45 hours of improvised jazz performances annotated by an automated signal processing pipeline. See our publication in Transactions of the International Society for Music Information Retrieval (DOI: 10.5334/tismir.186).

This repository contains the audio files used to create the annotations (both mixed, "raw" files, and unmixed, "stem" files processed using audio source separation models). Its purpose is to serve as a reference database for the design, evaluation, and implementation of various music information retrieval systems, including (but not limited to) onset detection, beat tracking, automatic music transcription, and automatic performer identification.

No annotations or metadata are provided with this archive; these can instead be found on the GitHub repository. Track names are consistent between audio, metadata, and annotations for a single track. All files are encoded as stereo 16-bit .WAV audio with a sample rate of 44.1 kHz.

Downloading:

We provide audio for JTD as two multi-part .zip files, one containing the unmixed audio and another containing the separated stems. After you've been granted access to the Zenodo record, the simplest way to download the entire database is to press the "Download all" button.

 

This will create a new file named files-archive (with no extension). Rename the file to files-archive.zip and extract using any unzipping tool (7zip, WinRAR, the unarchiver) or the command line. This will give you a list of multi-part zip files in the form [processed.zip.001, processed.zip.002, ...] and [raw.zip.001, raw.zip.002, ...]. 

To extract these, use 7zip from the command line with the following code:

7z x processed.zip.001

7z x raw.zip.001

Note that the default `unzip` command on Linux can't handle these files, so you'll need to use 7zip. You may also be able to use a GUI tool like WinRAR, which was used to create the archive in the first place. Also, be aware that each of those commands will extract all the wavs to the current folder, so you’ll likely need to move them afterwards.

Thanks to Xavier Riley for providing these instructions!
