IBC Sneak Peek: Comrex Introduces Opal IP Audio Gateway

Opus-based audio transport makes IBC debut

While many custom apps exist for audio transport over IP, common web browsers — which can be found on almost every smartphone or tablet — possess tremendous potential for live, high-quality, two-way communications.

Comrex has recently introduced a product to make use of these common browsers which can provide quality interviews with simple set-up.

The half-rack Comrex Opal provides near-studio quality audio with consumer grade equipment. Perfect for coordinating call-ins with guests who have no technical experience, Opal enables users to connect to the studio by clicking a link.

Opal makes it possible to do long interview segments in HD Voice quality, without requiring guests to install apps or fiddle with settings. Unlike Skype and other apps, the remote guest doesn’t install a thing — they just click a button, and go live.

Opal works by activating the Opus encoder built into commonly used browsers. As a result, Opal can connect to any computer or Android device with one of those browsers installed. All a remote guest needs to transmit audio is a browser and a microphone.

Opal uses Opus, a ubiquitous codec that is built into browsers like Chrome, Firefox, Microsoft Edge and Opera. Opus transmits high-fidelity, low-delay audio in both directions.

iOS users can connect to Opal with a free Comrex app since Safari browsers do not yet support the Opus coding algorithm.
