Opus 1.4 Royalty-Free Audio Codec Released

Written by Michael Larabel in Multimedia on 20 April 2023 at 06:31 AM EDT. 20 Comments

Opus 1.4 is available today as the first update in four years to this open-source, royalty-free versatile audio codec.

The last Opus library release was v1.3.1 as a bug-fix release all the way back in April 2019... Fast forward to today, Opus 1.4 is now available although it's not too significant of a release.

Most noticeable with Opus 1.4 is now having Meson build system support. Meson has become increasingly popular with open-source projects the past few years for its speedy build support with Ninja, much better cross-platform compatibility than Autotools, and other modern features.

Opus 1.4 also features improved tuning of the in-band FEC (LBRR), a new option to turn on FEC, and improved tuning and fixes to the DTX code.
