Libxtract: a Lightweight Library for audio Feature Extraction
نویسنده
چکیده
The libxtract library consists of a collection of over forty functions that can be used for the extraction of low level audio features. In this paper I will describe the development and usage of the library as well as the rationale for its design. Its use in the composition and performance of music involving live electronics also will be discussed. A number of use case scenarios will be presented, including the use of individual features and the use of the library to create a ’feature vector’, which may be used in conjunction with a classification algorithm, to extract higher level features.

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 کاملYAAFE, an Easy to Use and Efficient Audio Feature Extraction Software
Music Information Retrieval systems are commonly built on a feature extraction stage. For applications involving automatic classification (e.g. speech/music discrimination, music genre or mood recognition, ...), traditional approaches will consider a large set of audio features to be extracted on a large dataset. In some cases, this will lead to computationally intensive systems and there is, t...
