GuitarSet: A Dataset for Guitar Transcription
TLDR
GuitarSet is presented, a dataset that provides high quality guitar recordings alongside rich annotations and metadata that is interesting for a wide variety of tasks in addition to guitar transcription, including performance analysis, beat/downbeat tracking, and chord estimation.
Evaluating automatically estimated chord sequences
TLDR
This paper presents a rigorous scheme to describe evaluation methods in a sound, unambiguous way that extends previous work specifically to take into account the large variance in chord estimation vocabularies and to perform evaluations on select sets of chords.
20 Years of Automatic Chord Recognition from Audio
Comunicacio presentada a: 20th annual conference of the International Society for Music Information Retrieval (ISMIR) celebrat del 4 al 8 de novembre de 2019 a Delft, Paisos Baixos.
Combining Musicological Knowledge About Chords and Keys in a Simultaneous Chord and Local Key Estimation System
TLDR
It was found that chord estimation scores mostly depend on the integration of durational knowledge, while key estimation also requires prior information about the broader context, and the importance of integrating prior musicological knowledge into an automatic estimation system.
AUDIO CHORD EXTRACTION USING A PROBABILISTIC MODEL
TLDR
The front-end of the system uses multiple pitch tracking techniques to extract for each frame a chroma profile that is more robust against chroma contributions not originating from fundamental frequencies but from harmonics thereof, and the back-end implements a probabilistic framework for the simultaneous recognition of chords and keys.
Improved template based chord recognition using the CRP feature
TLDR
This work considers that the default parametrisation of CRP attenuates some tonal information, as well as timbral, and considers alternatives to this default, and provides a variant of a recently proposed compositional chroma feature, adapted for music pieces, rather than one instrument.
Cloud-smart Musical Instrument Interactions
TLDR
A smart guitar prototype is presented that allows retrieving songs from large online music databases using criteria different from conventional music search, which were derived from interviewing 30 guitar players.
Combining Harmony-Based and Novelty-Based Approaches for Structural Segmentation
TLDR
This paper describes a novel way to combine a well-proven method of structural segmentation through novelty detection with a recently introduced method based on harmonic analysis, which improves the results of both constituting components in isolation.
Integrating Musicological Knowledge into a Probabilistic Framework for Chord and Key Extraction
TLDR
A formerly developed probabilistic framework for the simultaneous detection of chords and keys in polyphonic audio is further extended and validated and an experimental study is conducted which sheds new light on the importance of musicological knowledge in the context of chord extraction.
