After more than two years of work, Opus 1.5 is out. It brings many new features that can improve quality and the general audio experience through machine learning, while maintaining fully-compatibility with previous releases. See this release page demonstrating all the new features including:
- Significant improvement to packet loss robustness using Deep Redundancy (DRED)
- Improved packet loss concealment through Deep PLC
- Low-bitrate speech quality enhancement down to 6 kb/s wideband
- Improved x86 (AVX2) and Arm (Neon) optimizations
- Support for 4th and 5th order ambisonics

The Mozilla Research RRNoise project shows how to apply deep learning to noise suppression. It combines classic signal processing with deep learning, but it’s small and fast. No expensive GPUs required — it runs easily on a Raspberry Pi. The result is easier to tune and sounds better than traditional noise suppression systems (been there!). And you can help! Find out how to donate your noise to science.

The Opus audio codec, used in WebRTC and now included in all major web browsers, gets another major upgrade with the release of version 1.2. This release brings quality improvements to both speech and music, while remaining fully compatible with RFC 6716. There are also optimizations, new options, as well as many bug fixes. This Opus 1.2 demo describes a few of the upgrades that users and implementers will care about the most. It includes audio samples comparing to previous versions of the codec, as well as speed comparisons for x86 and ARM.
