Automatic Transcription of Music How do we do
it?

Automatic Transcription of Music Approaches

• Pitch
• monophonic
• polyphonic
• Rhythm
• Sound separation
• Automatic transcription

4
Pitch monophonic

• methods are well established but susceptible to
  improvement
• Pitch Estimation using Multiple Independant
  Time-Frequency Windows
• Wide-band Pitch Estimation for Natural Sound
  Sources with Inharmonicities

5
Pitch polyphonic

• Area of intense investigation
• Number Theoretical Means of Resolving a Mixture
  of Several Harmonic Sounds
• Robust Multipitch Estimation for the Analysis
  and Manipulation of Polyphonic Musical Sounds

6
Pitch polyphonic

• Separation of Harmonic Sounds using Multipitch
  Analysis and Iterative Parametric Estimation
• Multipitch Estimation and Sound Separation by
  the Spectral Smoothness Principle
• Separation of Harmonic Sounds Using Linear
  Models for the Overtone Series

7
Rhythm

• Measuring the similarity of Rhythmic Patterns
• Locating Segments with Drums in Music Signals
• Sound Onset Detection by Applying Psychoacoustic
  Knowledge
• Qualitative and Quantitative Aspects in the
  Design of Periodicity Estimation Algorithms

8
Sound separation

• Separate spectral/inharmonic, scene recognition
• Recognition of Everyday Auditory Scenes
• Efficient Calculation of a Physiologically
  Motivated Representation for Sound
• Means of Integrating Audio Content Analysis
  Algorithms
