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.
