Real-Time Transcription and Separation of Drum Recordings Based on NMF Decomposition

  title={Real-Time Transcription and Separation of Drum Recordings Based on NMF Decomposition},
  author={Christian Dittmar and Daniel G{\"a}rtner},
This paper proposes a real-time capable method for transcribing and separating occurrences of single drum instruments in polyphonic drum recordings. Both the detection and the decomposition are based on Non-Negative Matrix Factorization and can be implemented with very small systemic delay. We propose a simple modification to the update rules that allows to capture timedynamic spectral characteristics of the involved drum sounds. The method can be applied in music production and music education… CONTINUE READING
