A note about the future of ecsoft2.org

ecsoft2.org runs on software (Drupal 7 and PHP 7.4) that reached its end of life years ago and no longer receives security updates. Keeping the site online safely is getting harder.

Giving it a future means migrating it to a current platform — and that is only worth doing if people still use it and want to help keep it alive.

If you care about ecsoft2.org, as a user, a contributor, or someone willing to lend a hand, please ggambatiscali [dot] it (get in touch) by January 31, 2027.

If no one comes forward by then, the site will be turned into a read-only archive, so that its content stays available.

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec. Opus can be adjusted seamlessly between high and low bitrates, and internally, it transitions between a linear prediction codec at lower bitrates and a transform codec at higher bitrates (as well as a hybrid for a short overlap).

Opus has a very low algorithmic delay (22.5 ms by default), which is a necessity for use as part of a low audio latency communication link, which can permit natural conversation, networked music performances, or lip sync at live events. Packages include Library for developers an tools for decoding/encoding audio files.

This software is distributed in two modes:

as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.

Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.
