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.

Ever thought that there were too many audio codecs, each with its own special niche? So did we, so we made a new one (1). The difference is that Opus scales from very low bit-rate VoIP to high-fidelity, low delay music transmission. It can be used for anything from making phone calls, to remote jam sessions, to archiving your music collection. It's better at speech than Speex, and better at music than Vorbis and MP3.

Since YouTube re-compresses all audio to a godawful implementation of AAC, the quality here will be marginally worse than the actual file. For instance, the high-frequency artifacts in this YouTube clip are NOT from the Opus encoding: They are from YouTube's terrible AAC encoder. (Vimeo is MUCH better.) Nevertheless, you will get an idea of what type of natural voice audio can be delivered over a DS0, with only 20ms of latency. Yes a DS0 is 64kbps, but I figured - why not allow for a few kbps of signaling and other stuff? :)
My understanding is that the speech codes in CDMA, GSM, and UMTS networks have a higher latency than this. Obviously G.711 would have MUCH less, right?
Opus allows as low as 2.5ms of latency, but 20-60 make the codec behave truly as a state of the art streaming audio codec. Quite frankly, I would love to setup an internet radio station with Opus at 96-128kbps: It would beat out mp3, Vorbis, and AAC!
This audio sample is from my crazy production thesis. :)

Opus is a state-of-the-art royalty-free lossy audio codec convering more applications than any other single audio codec— from low latency VoIP to high fidelity music storage. After five years of open development, including contributions from Xiph.Org, Skype/Microsoft, Mozilla, Broadcom, and many individual developers, Opus was standardized in 2012 by the IETF in RFC 6716 and has since been deployed to hundreds of millions of computers and devices.
Daala is a new open effort to build a state-of-the-art video codec targeting compression performance beyond HEVC and VP9. Leveraging the experience we had with Opus we are building a new technical framework for video coding the ground up to avoid patent thickets and be royalty free: By breaking from the common design pattern of block based transform codecs we avoid many licensing complications and create an opportunity to better resolve some of the weaknesses of existing formats.
This talk will cover our success with Opus and our plans for Daala and how we will create codec infrastructure which is convincingly royalty free, has state-of-the-art performance, and can be easily deployed and integrated, with the hope that someday everyone can stop worrying about codecs and go on to build fantastic things without having to compromise on performance or navigating licensing.
Greg has worked on unencumbered multimedia codecs with the Xiph.Org Foundation since 1999 and is currently working for Mozilla on next-generation royalty-free video coding standards.

This is a comparison of codecs all on the highest quality (10). This is a small clip from a track I made and it perfectly demonstrates the, just horrible, quality of the new Opus Music codec. I tried this before a while ago way before the final version of this new update was released and it was so good quality I could not believe it, I literally could not tell the difference between streaming the music over teamspeak vs listening to it natively on my PC's music player.

This Video reveals a "Bug" in the OPUS CODEC implementation of MUMBLE.
The CPU gets hammered from the start after opening mumble. After going to output settings, and selecting loopback/server mode while in continuous transmission mode for mumble input, the CPU really goes haywire, and a full spectrum of audio white noise starts pulsing; - see @ 3 minutes 25 second mark-- the CPU gets locked up and slows down everything on the desktop. It has even frozen everything on my computer where nothing worked and I had to do a "hard" reboot.
This video is made with full respect to the MUMBLE DEV's and the MUMBLE community, in hopes that it will help improve the mumble OPUS implementation.
The computer in this video is an i7 quad core Samsung laptop with a REALTEK HD AUDIO soundcard.
The "white noise" audio pulsing starts after the output LOOPBACK/SERVER is started.
check at about 3min 25 seconds for the audio pulsing...after one short tone is sent into the mumble input...A spectrum analyzer is used(voxengo's SPAN) to show how wideband the pulsing noise is and that is starts before any tone or audio is sent to the mumble input and after a single tone is sent, the noise pulsing starts again and continues indefinitely, even though no other audio input is again sent to mumble input.

Opus (audio format)
Opus is a lossy audio coding format developed by Xiph and standardized by the IETF, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low end ARM3 processors. Opus replaces both Vorbis and Speex, and several blind listening tests have ranked it higher quality than any other standard audio format at any given bitrate, including MP3, AAC, and HE-AAC.
Opus combines the speech-oriented linear predictive coding SILK algorithm, and the lower-latency, MDCT-based CELT algorithm, switching between or combining them as needed for maximum efficiency. Bitrate, audio bandwidth, complexity, and algorithm can all be adjusted seamlessly in each frame. Opus has the low algorithmic delay (26.5Â ms by default) necessary for use as part of a real-time communication link, permitting natural conversation, networked music performances, and live lip sync; by trading-off quality or size the delay can be reduced down to 5Â ms. Its delay is exceptionally low compared to competing codecs, which require well over 100Â ms, yet Opus performs very competitively with these formats in terms of quality per bitrate.

Codec
A codec is a device or computer program capable of encoding or decoding a digital data stream or signal.Codec is a portmanteau of coder-decoder or, less commonly, compressor-decompressor.
A codec encodes a data stream or signal for transmission, storage or encryption, or decodes it for playback or editing. Codecs are used in videoconferencing, streaming media, and video editing applications. A video camera's analog-to-digital converter (ADC) converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage. A receiving device then runs the signal through a video decompressor, then a digital-to-analog converter (DAC) for analog display.
Related concepts
In the mid 20th century, a codec was a hardware device that coded analog signals into digital form using pulse-code modulation (PCM). Late in the century the name was also applied to a class of software for converting between different digital signal formats, including compander functions.

This talk will cover our success with Opus and our plans for Daala and how we will create codec infrastructure which is convincingly royalty free, has state-of-the-art performance, and can be easily deployed and integrated, with the hope that someday everyone can stop worrying about codecs and go on to build fantastic things without having to compromise on performance or navigating licensing.
Greg has worked on unencumbered multimedia codecs with the Xiph.Org Foundation since 1999 and is currently working for Mozilla on next-generation royalty-free video coding standards.

This is a comparison of codecs all on the highest quality (10). This is a small clip from a track I made and it perfectly demonstrates the, just horrible, quality of the new Opus Music codec. I tried this before a while ago way before the final version of this new update was released and it was so good quality I could not believe it, I literally could not tell the difference between streaming the music over teamspeak vs listening to it natively on my PC's music player.

This Video reveals a "Bug" in the OPUS CODEC implementation of MUMBLE.
The CPU gets hammered from the start after opening mumble. After going to output settings, and selecting loopback/server mode while in continuous transmission mode for mumble input, the CPU really goes haywire, and a full spectrum of audio white noise starts pulsing; - see @ 3 minutes 25 second mark-- the CPU gets locked up and slows down everything on the desktop. It has even frozen everything on my computer where nothing worked and I had to do a "hard" reboot.
This video is made with full respect to the MUMBLE DEV's and the MUMBLE community, in hopes that it will help improve the mumble OPUS implementation.
The computer in this video is an i7 quad core Samsung laptop with a REALTEK HD AUDIO soundcard.
The "white noise" audio pulsing starts after the output LOOPBACK/SERVER is started.
check at about 3min 25 seconds for the audio pulsing...after one short tone is sent into the mumble input...A spectrum analyzer is used(voxengo's SPAN) to show how wideband the pulsing noise is and that is starts before any tone or audio is sent to the mumble input and after a single tone is sent, the noise pulsing starts again and continues indefinitely, even though no other audio input is again sent to mumble input.
