Introduction:

Divide and Remaster (DnR) is a source separation dataset for training and testing algorithms that separate a monaural audio signal into speech, music, and sound effects/background stems. The dataset is composed of artificial mixtures using audio from the librispeech, free music archive (FMA), and Freesound Dataset 50k (FSD50k). We introduce it as part of the Cocktail Fork Problem paper.

 

At a Glance:

  • The size of the unzipped dataset is ~174GB
  • Each mixture is 60 seconds long and sources are not fully overlapped
  • Audio is encoded as 16-bit .wav files at a sampling rate of 44.1 kHz
  • The data is split into  training tr (3295 mixtues), validation cv (440 mixtures) and testing tt (652 mixtures) subsets
  • The directory for each mixture contains four .wav files, mix.wav, music.wav, speech.wav, sfx.wav, and annots.csv which contains the metadata for the original audio used to compose the mixture (transcriptions for speech, sound classes for sfx, and genre labels for music)
