PIANO-AUG - Piano Multipitch Estimation with Augmentation Dataset

This dataset includes a 29 minutes long piano recording with a total of 4584 notes. The recording includes sections of single notes as well as groups of simultaneously sounding notes (intervals, chords), which ascend chromatically within the MIDI pitch range [21,92].

In particular, the segments cover single notes, intervals (two-note groups), as well as common three- voiced and four-voiced chords. It must be noted that we do not investigate chord inversions here, all chords are used in their root position.

The audio is created by rendering the MIDI file using the “Grand Piano” plugin in Ableton Live 8 with default settings except from the “Reverb Amount” being set to zero.

The pedalboard python library (0.4.1) can be used to create multiple augmented versions of the unprocessed piano recording. In particular, we create pairs of mild (-) and heavy (+) augmentations for each of the compression (comp), gain (gain), low-pass filter (lpf), and reverb (rev) effects using this Python script
