Instead of a standard Fourier-based spectrogram, it applies a bank of gammatone filters\u2014whose bandwidth increases with center frequency\u2014to model how the human auditory system perceives sound. The result is a time-varying spectrum that better matches human hearing than linear frequency analysis, with lower frequencies appearing more spread out and features appearing more intuitively positioned.\n\nThe package depends on numpy, scipy, and matplotlib, and runs on Python 3.8+. It can be used as a command-line tool to visualize audio files as gammatone spectrograms, or imported as a library for programmatic signal analysis. The repository is archived and no longer maintained, so it is stable but receives no updates.","worth_installing":"Yes, if you need perceptually-motivated audio analysis and can accept an abandoned codebase. The package is stable, has no known vulnerabilities, and low install friction. However, verify the unclear license before use in proprietary work, and do not expect bug fixes or maintenance. Best suited for research, education, or stable production use where no ongoing support is required."},"id":"gammatone","links":{"html":"https://skillfed.io/packages/gammatone","md":"https://skillfed.io/packages/gammatone.md","pypi":"https://pypi.org/project/gammatone/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2024-09-10","license_spdx":null,"license_treatment":"unclear","name":"Gammatone","python_support":"supports_current","summary":null},"popularity":{"monthly_downloads":90925,"position":13555,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.3"}
