Drum Source Separation using Percussive Feature Detection and Spectral Modulation
نویسندگان
چکیده
We present a method for the separation and resynthesis of drum sources from single channel polyphonic mixtures. The frequency domain technique involves identifying the presence of a drum using a novel percussive feature detection function, after which the short-time magnitude spectrum is estimated and scaled according to an estimated time-amplitude function derived from the percussive measure. In addition to producing high quality separation results, the method we describe is also a useful pre-process for drum transcription techniques such as Prior Subspace Analysis in the presence of pitched instruments. Keywords-Audio, Signal Processing, Source Separation, Drum. __________________________________________________________________________________________

Automatic Drum Transcription Using Bi-Directional Recurrent Neural Networks
Automatic drum transcription (ADT) systems attempt to generate a symbolic music notation for percussive instruments in audio recordings. Neural networks have already been shown to perform well in fields related to ADT such as source separation and onset detection due to their utilisation of time-series data in classification. We propose the use of neural networks for ADT in order to exploit the...
متن کاملTimbre-Based Percussive Rhythm Classification and Retrieval
Evidence within music information research suggest that timbre plays a more important role in rhythmic similarity than previously thought, as shown by M. Haro, P. Herrera [1]. Similar to other recent rhythm feature classification techniques, our system aims to use timbre as a primary method for establishing context between inter-instrument features [2], further informed by [3]. Namely, source c...
متن کاملA Segmental Spectral Flatness Measure for Harmonic-Percussive Discrimination
In a variety of applications of audio signal processing, for example blind source separation (BSS), harmonic signals need to be treated differently from percussive signals. Thus, recognizing if a signal is harmonic or percussive is a very helpful and frequently used preprocessing step. Different measures have been proposed to capture either the harmonicity or the percussivity of a signal, using...

In automatic music transcription, metadata extraction from recorded audio data or speaker separation in video conferencing, it is a significant prerequisite task to analyze and separate the audio signal into their original source components. In this report, I study and analyze a set of methods of the extraction of percussive instruments metadata from polyphonic music. It mainly focuses on the s...
متن کاملHarmonic-Percussive Source Separation Using Harmonicity and Sparsity Constraints
In this paper, we propose a novel approach to harmonicpercussive sound separation (HPSS) using Non-negative Matrix Factorization (NMF) with sparsity and harmonicity constraints. Conventional HPSS methods have focused on temporal continuity of harmonic components and spectral continuity of percussive components. However, it may not be appropriate to use them to separate time-varying harmonic sig...
