Opus examples

Audio samples

These samples demonstrate the quality achievable with Opus. They are have been encoded with Opus and thendecoded back to wav so that any browser can play them. The bitrates indicated are target bitrates, i.e.the average that would be achieved on a large audio collection.

Bitrate scalability

The following example demonstrates what happens when gradually varying the bitrate from 8 kb/s to 64 kb/s.It’s an extreme example, but it shows how Opus can change bandwidth and bitrate seamlessly without any glitch.In practical applications, bitrate changes are expected to occur much more slowly.

Stereo

Mono

Example of use in a web page

Opus works with the<audio> element just like Vorbis. For example, this code in a web page<audio src="ehren-paper_lights-96.opus" controls></audio>displays an embedded player that can play an Opus file:

Paper Lights byEhren Starks, encoded at 96 kb/s

Your browser does not support the audio element

Playback should work in Firefox or Chrome.

There is also a list of live Opus internet radio streams on theIcecast directory.
