It provides algorithms for feature extraction, spectral analysis, and music analysis tasks. The library depends on scientific computing foundations (numpy, scipy, scikit-learn) and uses numba for performance-critical code, plus soundfile and soxr for audio I/O and resampling.\n\nDevelopers use librosa to extract features from audio (mel-spectrograms, chroma, MFCC, onset detection), analyze musical structure, and build systems that understand or process music. It's production-stable (Development Status 5), actively maintained with a recent release, and widely adopted in music technology and research.","worth_installing":"Yes. librosa is production-stable, actively maintained, has low install friction, carries a permissive license, and is the standard Python library for audio and music signal processing. Install it if you need to work with audio features, music analysis, or MIR tasks. No known security vulnerabilities."},"id":"librosa","links":{"html":"https://skillfed.io/packages/librosa","md":"https://skillfed.io/packages/librosa.md","pypi":"https://pypi.org/project/librosa/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-11","license_spdx":null,"license_treatment":"permissive","name":"librosa","python_support":"supports_current","summary":"Python module for audio and music processing"},"popularity":{"monthly_downloads":13551389,"position":1274,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.0.0"}
