It decomposes audio into three acoustic features: f0 (pitch contour), sp (harmonic spectral envelope), and ap (aperiodicity), which can then be modified and resynthesized. The package provides low-level functions (dio, stonemask, cheaptrick, d4c) for each analysis step, plus a convenience function (wav2world) that applies all steps with default parameters.\n\nThe package depends only on numpy and wraps compiled C++ code, so installation involves building against the bundled WORLD library. Prebuilt wheels are available for Windows and several Python versions, but Linux and macOS users typically need to compile. The project is dormant (last commit 2025-01-21, no recent activity), though it remains functional and has no known vulnerabilities.","worth_installing":"Yes, if you need speech vocoding and can tolerate compilation friction. PyWorld is stable, has no known vulnerabilities, and is well-suited for speech analysis and synthesis tasks. However, verify the license terms first (they are not recorded in package metadata), and be aware that the project is dormant\u2014expect no active maintenance. Windows users will have the easiest installation experience."},"id":"pyworld","links":{"html":"https://skillfed.io/packages/pyworld","md":"https://skillfed.io/packages/pyworld.md","pypi":"https://pypi.org/project/pyworld/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2025-01-20","license_spdx":null,"license_treatment":"unclear","name":"pyworld","python_support":"unspecified","summary":"PyWorld: a Python wrapper for WORLD vocoder"},"popularity":{"monthly_downloads":209434,"position":9513,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.5"}
