Database Content

The IDMT-SMT-Bass database is a large database for automatic bass transcription and signal processing.

The overall duration of the audio material is approx. 3.6 hours.

The dataset consists of approx. 4300 WAV files (44.1 kHz, 24bit) with single recorded notes.

Overall, 10 different bass-related playing techniques namely 5 plucking styles

  • fingerstyle (FS)
  • picked (PK)
  • muted (MU)
  • slap-thumb (ST)
  • slap-pluck (SP)

and 5 expression styles

  • normal (NO)
  • vibrato (VI)
  • bending (BE)
  • harmonics (HA)
  • dead-note (DN)

are incorporated. A further explaination of the playing techniques is provided in [1].

For each of the three expression techniques (vibrato, bending, slide), two subclasses were defined in [2]:

  • fast vibrato, slow vibrato
  • semi-tone bending, quarter-note bending
  • slide up, slide down (recorded with fretless bass guitar)

3 different 4-string electric bass guitars, each with 3 different pick-up settings were used for recording.

The notes cover the common pitch range of a 4-string bass guitar from E1 (41.2 Hz) to G3 (196.0 Hz).
