LibXtract
A portable C library for efficient audio feature extraction with a cascading design for performance and flexibility.
What is LibXtract?
LibXtract is a simple, portable, and lightweight C library for audio feature extraction. It provides a comprehensive set of functions to compute features like statistical moments, spectral irregularity, and MFCCs from audio signals. The library is designed with a cascading architecture to minimize redundant calculations when extracting multiple features.
Audio signal processing developers, researchers in music information retrieval, and engineers building real-time audio analysis tools who need efficient, low-level feature extraction in C or Python.
Developers choose LibXtract for its unique cascading design that eliminates redundant computations, its portability across platforms, and its comprehensive set of audio feature primitives that can be flexibly combined for custom extraction pipelines.
