audioop-lts

What it is and what it does

audioop-lts is a long-term support port of the `audioop` module, which was deprecated in version 3.11 and removed in 3.13. The module provides low-level audio processing functions for manipulating raw audio samples—operations like mixing, format conversion, and signal analysis that were previously available in the standard library. Since the module was removed, projects that depend on it need an external package to continue functioning.

The package is designed as a drop-in replacement: you import it the same way and call the same functions. It has no runtime dependencies and is distributed as pre-compiled wheels for most major platforms and architectures. The main constraint is the hard requirement for supported versions—it will not install or run on earlier versions, so you should use environment markers in your dependency declaration to avoid installation attempts on unsupported versions.

Use it for:

• Migrate code that used the removed `audioop` module without rewriting audio processing logic.
• Perform basic audio sample operations like mixing, format conversion, or amplitude analysis.
• Support legacy audio tools or libraries that depend on `audioop` functions when upgrading.
• Prototype audio signal manipulation without external audio libraries.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides the `audioop` module for Python 3.13+, restoring audio processing functions that were removed from the standard library.

Yes, if you need `audioop` functions on supported versions. It is a straightforward, permissively licensed restoration of a removed standard library module with no dependencies. However, the aging maintenance status (374 days since last release) means you should monitor it for compatibility issues. Use environment markers to avoid installation on unsupported versions.

Install

audioop-lts on PyPI

pip install audioop-lts

uv add audioop-lts

poetry add audioop-lts

Installing audioop-lts

Before you install

Medium install friction due to compiled wheels across multiple platforms. Maintenance status is aging—last release was 374 days ago—so expect slower response to issues or compatibility updates.

License in practice

Licensed under PSF-2.0 (permissive), allowing free use, modification, and distribution with minimal restrictions.

Quickstart

pip install audioop-lts

import audioop
# Process audio samples
result = audioop.add(fragment1, fragment2, width)

Requires Python 3.13 or greater; will not function on earlier versions.

Verify before relying

• Feature parity with the original removed `audioop` module—whether all functions and behavior are fully preserved.
• Whether this package will continue to receive updates as newer versions release.
• Specific audio processing functions available and their exact behavior.
