In a previous blogpost we talked about the Opus codec, which offers very low bitrates. Another codec seeking to achieve even lower bitrates is Codec 2.

Codec 2 is designed for use with speech only, and although the bitrates are impressive the results aren’t as clear as Opus, as you can hear in the following audio examples. However, there is some interesting work being done with Codec 2 in combination with neural network (WaveNets) that is yielding great results.

Do you know what's great about text? It's really easy to find stuff! You just do a quick search on that website you bookmarked last week, and boom! – there is the name of that book that you had read about, but whose title you had forgotten. But on the downside, text is not always the best medium to consume information, for example while you are driving a car. That's why we like podcasts: you can listen to them while you are driving, walking, exercising, etc. Podcasts keep your hands free and your eyes on the environment around you.

The ...

We are very happy that Opus, an exciting new open audio codec, is now officially standardized by the Internet Engineering Task Force (IETF). Opus is particularly interesting for podcasts, radio books and internet audio in general due to its suitability for both, music and speech, and its outstanding sound quality at also very low bitrates.
In this article, we will listen to some examples of the Opus codec in action and have a closer look at the codec and how audio producers can benefit from it.

Why Opus?

Opus is a lossy audio codec that has ...
