Js-xtract: a Realtime Audio Feature Extraction Library for the Web
نویسندگان
چکیده
JS-Xtract is an efficient modular JavaScript library for audio feature extraction, capable of operating on arbitrary time-series data, or being bound to Web Audio objects. The library implements an extensive range of vector and scalar feature extractors, and allows both procedural and object-oriented function calls. We show it performs well across a range of desktop and mobile browsers, and is capable of extracting audio features in realtime.

This paper describes updates to the Greenstone open source digital library software that significantly expand its functionality with respect to music. The first of the two major improvements now allows Greenstone to extract and store classification-oriented features from audio files using a newly updated version of the jAudio software. The second major improvement involves the implementation an...
متن کاملOntological Representation of Audio Features
Feature extraction algorithms in Music Informatics aim at deriving statistical and semantic information directly from audio signals. These may be ranging from energies in several frequency bands to musical information such as key, chords or rhythm. There is an increasing diversity and complexity of features and algorithms in this domain and applications call for a common structured representati...

متن کاملراهکار جدید استخراج ویژگی مبتنی بر نمونه‌برداری فشرده در پردازش سیگنال‌های صوتی
In this paper, we present a Compressive Sampling (CS)-based feature extraction method for audio signals. In the proposed approach, the audio signal is firstly segmented by hamming windows and the Discrete Fourier Transform (DFT) of the samples is calculated within each frame. Then, the normalized values of the DFT coefficients of each frame are accumulated. At the next step, the second DFT is a...
متن کاملAn Ontology for Audio Features
A plurality of audio feature extraction toolsets and feature datasets are used by the MIR community. Their different conceptual organisation of features and output formats however present difficulties in exchanging or comparing data, while very limited means are provided to link features with content and provenance. These issues are hindering research reproducibility and the use of multiple too...
