This page is intended to supplement the lecture material found in the class - providing extra tutorials, support, references for further reading, or demonstration code snippets for those interested in a given topic. Please contribute to this growing list of resources. Do you have a great explanation of how a technique works? Found a great Java applet that illustrates a concept? Discovered a great survey of the field for a particular area? Please add it for the benefit of future students. Thanks!

I encourage you to ADD links and sections - but please do not REMOVE headings or items from the page.

Tempo Extraction

Feature Extraction

Low Level Features

  • Zero Crossing, Temporal centroid, Log Attack time, Attack slope), Spectral features (Centroid, Flux, RMS, Rolloff, Flatness, Kurtosis, Brightness),Spectral bands, Log spectrogram
  • Chroma bins
  • MFCC
  • MPEG-7

Higher-level features

  • Key Estimation
  • Chord Estimation
  • Genre (genre, artist ID, similarity)
  • "Fingerprints"

Visualizing and Sonifying Feature data

Analysis / Decision Making

Classification

Clustering and probability density models

  • Density distance measures (centroid distance, EMD, KL-divergence, etc)
  • k-Means
  • Clustering Demo

Clustering

HMM

There are a couple of MATLAB toolboxes for implementing HMMs and Bayesian nets, both by Kevin Murphy:

Nested classifier / Anchor-space / template-based systems

  •  ?

Model / Data Preparation Techniques

  • Data Preparation
    • PCA / LDA
    • Scaling data
  • Model organization
    • concept, design, data set construction and organization

Evaluation Methodology

  • Cross Validation
  • Information Retrieval metrics (precision, recall, F-Measure)

Real-world applications

Audio Segmentation

Automatic Audio Segmentation: Segment Boundary and Structure Detection in Popular Music

Audio Fingerprinting

The Last.fm fingerprinter uses this approach, code can be checked out from: svn://svn.audioscrobbler.net/recommendation/MusicID/lastfm_fplib
