It accepts audio as 2D arrays (channels \u00d7 samples) and outputs processed audio in the same format, supporting both mono and multichannel audio with independent control of pitch (via semitone shifts) and playback speed (via time factor).\n\nThe package is actively maintained, has prebuilt wheels for Python 3.10\u20133.12 across macOS, Linux, and Windows, and carries no known security vulnerabilities. It is a thin binding to a mature C++ algorithm library, so installation is straightforward on supported platforms, though building from source requires a C++ compiler and CMake.","worth_installing":"Yes. The package is actively maintained, has no known vulnerabilities, carries a permissive MIT license, and offers a straightforward interface to a proven C++ algorithm. Install friction is moderate but manageable via prebuilt wheels on common platforms. It is a good choice if you need reliable pitch shifting and time stretching."},"id":"python-stretch","links":{"html":"https://skillfed.io/packages/python-stretch","md":"https://skillfed.io/packages/python-stretch.md","pypi":"https://pypi.org/project/python-stretch/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-02-14","license_spdx":null,"license_treatment":"permissive","name":"python-stretch","python_support":"supports_current","summary":"Simple python library for pitch shifting and time stretching"},"popularity":{"monthly_downloads":183267,"position":10069,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.1"}
