Fast approximated power iteration subspace tracking
TLDR
This paper introduces a fast implementation of the power iteration method for subspace tracking, based on an approximation that is less restrictive than the well-known projection approximation, and guarantees the orthonormality of the subspace weighting matrix at each iteration.

Source/Filter Model for Unsupervised Main Melody Extraction From Polyphonic Audio Signals
TLDR
A new signal model is proposed where the leading vocal part is explicitly represented by a specific source/filter model and reaches state-of-the-art performances on all test sets.

Melody Extraction from Polyphonic Music Signals: Approaches, applications, and challenges
TLDR
A case study that interprets the output of a melody extraction algorithm for specific excerpts and a comprehensive comparative analysis of melody extraction algorithms based on the results of an international evaluation campaign are provided.

Vocal detection in music with support vector machines
TLDR
A temporal smoothing of the posterior probabilities with a hidden Markov model that helps adapting the segmentation sequence to the precision of the manual annotation in a polyphonic musical signal.

Signal Processing for Music Analysis
TLDR
It is demonstrated that, to be successful, music audio signal processing techniques must be informed by a deep and thorough insight into the nature of music itself.

A Musically Motivated Mid-Level Representation for Pitch Estimation and Musical Audio Source Separation
TLDR
A source/filter signal model which provides a mid-level representation which makes the pitch content of the signal as well as some timbre information available, hence keeping as much information from the raw data as possible.

Transcription and Separation of Drum Signals From Polyphonic Music
  • O. Gillet, G. Richard
  • Computer Science
    IEEE Transactions on Audio, Speech, and Language…
  • 1 March 2008
TLDR
A complete drum transcription system is described, which combines information from the original music signal and a drum track enhanced version obtained by source separation, and which integrates a large set of features, optimally selected by feature selection.

Events Detection for an Audio-Based Surveillance System
TLDR
The automatic shot detection system presented is based on a novelty detection approach which offers a solution to detect abnormality (abnormal audio events) in continuous audio recordings of public places and takes advantage of potential similarity between the acoustic signatures of the different types of weapons by building a hierarchical classification system.

YAAFE, an Easy to Use and Efficient Audio Feature Extraction Software
TLDR
In this paper, a new audio feature extraction software, YAAFE 1, is presented and compared to widely used libraries and the main advantage is a significantly lower complexity due to the appropriate exploitation of redundancy in the feature calculation.
Temporal Integration for Audio Classification With Application to Musical Instrument Classification
TLDR
A number of methods for early and late temporal integration are proposed and an in-depth experimental study on their interest for the task of musical instrument recognition on solo musical phrases is provided.
