Description<br>
-----------

Bach10-mf0-synth contains 10 classical music pieces (four-part J.S. Bach chorales) from the Bach10 dataset <br>
(http://music.cs.northwestern.edu/data/Bach10.html) where each instrument (bassoon, clarinet, saxophone and violin) has <br>
been resynthesized to obtain perfect f0 annotations using the analysis/synthesis method described in the following <br>
publication:

J. Salamon, R. M. Bittner, J. Bonada, J. J. Bosch, E. Gómez, and J. P. Bello. "An analysis/synthesis framework for <br>
automatic f0 annotation of multitrack datasets". In 18th Int. Soc. for Music Info. Retrieval Conf., Suzhou, China, <br>
Oct. 2017.

This dataset includes:<br>
* 10 mono wav files of mixes where each instrument (bassoon, clarinet, saxophone and violin) has been resynthesized <br>
  using the analysis/synthesis method described in the paper.<br>
* 10 csv files containing a perfect multiple-f0 annotation of all the instruments in the mix, obtained via the <br>
  analysis/synthesis method described in the paper<br>
* 40 mono wav files consisting of the individual solo stems (tracks) for every instrument in each of the 10 pieces, <br>
  resynthesized using the analysis/synthesis method described in the paper.<br>
* 40 csv files containing a perfect f0 annotation for every instrument in each of the 10 pieces, obtained using the <br>
  analysis/synthesis method described in the paper.

The data come in four folders, the contents of which is described below.

<br>
audio_mix<br>
---------<br>
Contains 10 mono wav files of mixes where each instrument (bassoon, clarinet, saxophone and violin) has been <br>
resynthesized using the analysis/synthesis method described in the paper. The mix is obtained by taking an unweighted<br>
sum of the resynthesized solo stems (tracks).

Naming convention: <br>
&lt;pieceID&gt;_&lt;title&gt;_MIX_mf0synth.wav

Example: <br>
01_AchGottundHerr_MIX_mf0synth.wav

<br>
annotation_mf0<br>
--------------<br>
Contains 10 csv files containing a perfect multiple-f0 annotation of all instruments in the mix, obtained via the <br>
analysis/synthesis method described in the paper. 

Format:<br>
The annotations follow the MIREX multiple-f0 estimation (frame-basis) format:<br>
https://www.music-ir.org/mirex/wiki/2018:Multiple_Fundamental_Frequency_Estimation_%26_Tracking#I.2FO_format<br>
This format is also support by mir_eval: https://github.com/craffel/mir_eval

Each row in the annotation starts with a timestamp, followed by 0 or more tab separated frequency values in Hz <br>
representing the f0 of each active pitched instrument present in the time frame represented by the row. The hop size <br>
of the annotation is exactly 10 ms. 

IMPORTANT: no assumptions can be made as to the ordering of the f0 values in each row. The frequency values are NOT <br>
ordered neither by instrument nor by frequency, and should thus be treated as a "bag of frequencies" (a set) without <br>
any assumptions as to which frequency belongs to which instrument.

Naming convention:<br>
&lt;pieceID&gt;_&lt;title&gt;_MIX_mf0synth.csv

Example:<br>
01_AchGottundHerr_MIX_mf0synth.csv

<br>
audio_stems<br>
-----------<br>
Contains 40 mono wav files consisting of the individual solo stems (tracks) for every instrument in each of the <br>
10 pieces, resynthesized using the analysis/synthesis method described in the paper.

Naming convention: <br>
&lt;pieceID&gt;_&lt;title&gt;_&lt;instrument&gt;.RESYN.wav

Example: <br>
01_AchGottundHerr_bassoon.RESYN.wav

<br>
annotation_stems<br>
----------------<br>
Contains 40 csv files containing a perfect f0 annotation for every instrument in each of the 10 pieces, obtained using <br>
the analysis/synthesis method described in the paper.

Format:<br>
Each file contains two comma-separated columns, the first containing timestamps and the second containing the stem <br>
f0 in Hz. The first frame in the annotation is zero-centered. Silence is indicated as 0 Hz. The hop size of the <br>
annotation is 128/44100 seconds (~2.9 ms).

Naming convention:<br>
&lt;pieceID&gt;_&lt;title&gt;_&lt;instrument&gt;.RESYN.csv

Example:<br>
01_AchGottundHerr_bassoon.RESYN.csv
