“Drums DB tools” – project overview


  1. Production of beats in fast manner (less than 30 minutes per beat) requires database of tested and well known drum samples.
  2. Selection of best sounding drum samples requires browsing many different directories.
  3. Some samples have unacecptable quality to be used in professional productions and need to be removed
  4. Having metadata and feature representation of sounds enable finding similar sounds in terms of style, quality, origin and timbre. It might be useful for remixing and learning about timbres used by respected producers.


– Quality:

  1. Time of preparing a beat consisting of drums, sample/instrument track and baseline with 1:30 of simple arrangement
  2.  Number of samples rated 4 or 5
  3. Percentage of misclassified samples after manual verification

– Progress:

  1. Number of automatically pre-processed and classified samples in different categories
  2. Number of manually processed samples
  3. Number of commits to gitghub
  4. Degree of process automatiion
