MAPS Database: a Piano database for multipitch estimation and automatic transcription of music
By V. Emiya, B. David

MAPS, standing for MIDI Aligned Piano Sounds, is a piano sound database dedicated to research on multi-F0 estimation and automatic transcription:

MAPS is composed of about 31 GB of CD-quality recordings in .wav format.
High quality audio is obtained by means of Virtual Piano softwares and a Yamaha Disklavier.
Nine settings of different pianos and recording conditions were used.
Four categories of sounds are provided:
- isolated notes and monophonic sounds
- random chords
- usual chords
- pieces of music
The ground truth is provided for all sounds, in MIDI and text formats. The audio was generated from the ground truth in order to ensure the accuracy of the annotation.
MAPS is freely released with a Creative Commons license.
