Automatic Chord Recognition Using Quantised Chroma and Harmonic Change Segmentation
نویسنده
چکیده
This extended abstract describes an entry to the MIREX’09 (Music Information Retrieval eXchange) chord detection competition. The system described here uses a combination of two algorithms previously presented by the author. The system first calculates a quantised chromagram from the audio recording. It then uses a harmonic change detection function to segment the chroma features in time. The average chroma values for each segment are found and the results are then analysed by a simple chord recognition algorithm.

Feature Learning for Chord Recognition: The Deep Chroma Extractor
We explore frame-level audio feature learning for chord recognition using artificial neural networks. We present the argument that chroma vectors potentially hold enough information to model harmonic content of audio for chord recognition, but that standard chroma extractors compute too noisy features. This leads us to propose a learned chroma feature extractor based on artificial neural networ...
متن کاملAutomatic Chord Detection Using Harmonic Sound Emphasized Chroma from Musical Acoustic Signal
In this abstract we describe a method to automatically detect chord progression from musical acoustic signal. We suppress drum sounds because most popular music contains drum and such non-harmonic sound prevend to detect chord. We use Harmonic/Percussive sound separation tecnique, developed in our laboratory to get harmonic emphasized signal, then we use chroma vector and hidden Markov models t...
متن کاملAutomatic chord transcription from audio using computational models of musical context
This thesis is concerned with the automatic transcription of chords from audio, with an emphasis on modern popular music. Musical context such as the key and the structural segmentation aid the interpretation of chords in human beings. In this thesis we propose computational models that integrate such musical context into the automatic chord estimation process. We present a novel dynamic Bayesi...
متن کاملLyrics-to-audio Alignment and Phrase-level Segmentation Using Incomplete Internet-style Chord Annotations
We propose two novel lyrics-to-audio alignment methods which make use of additional chord information. In the first method we extend an existing hidden Markov model (HMM) for lyrics alignment [1] by adding a chord model based on the chroma features often used in automatic audio chord detection. However, the textual transcriptions found on the Internet usually provide chords only for the first a...
متن کاملExploring Common Variations in State of the Art Chord Recognition Systems
Most automatic chord recognition systems follow a standard approach combining chroma feature extraction, filtering and pattern matching. However, despite much research, there is little understanding about the interaction between these different components, and the optimal parameterization of their variables. In this paper we perform a systematic evaluation including the most common variations i...
