**Deprecation Notice:** This library will be replaced with the [AV library](https://github.com/php-webrtc/av) in a future update.

A lightweight PHP wrapper for the [libopus](https://opus-codec.org/) audio codec using PHP FFI.
This package provides encoder and decoder classes for working with raw PCM audio and the Opus format.

About this fork
---------------

[](#about-this-fork)

This is the `danog/php-rtc-opus` fork used by MadelineProto. It targets PHP 8.2+, loads and publishes the libopus FFI binding lazily after validating the native library, and therefore does not require FFI merely to install the wider WebRTC stack.

All internal Composer dependencies use their `danog/php-rtc-*` package names directly, so installing a component selects the maintained danog packages throughout the dependency graph.

Features
--------

[](#features)

- Encode raw PCM audio to Opus format
- Decode Opus-encoded audio back to PCM
- Based on FFI bindings to the native libopus library
- Compatible with multi-channel and variable sample rate audio

Requirements
------------

[](#requirements)

- PHP ≥ 8.2
- FFI and libopus only when encoding or decoding audio
- Linux environment (Windows/macOS support planned)

Documentation
-------------

[](#documentation)

This package is part of the PHP WebRTC library. For complete documentation, examples, and API reference, visit:
