MAPS Database – A piano database for multipitch estimation and automatic transcription of music

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.
