2. Lyra (codec) - Wikipedia

   en.wikipedia.org/wiki/Lyra_(codec)

   The Lyra codec is designed to transmit speech in real-time when bandwidth is severely restricted, such as over slow or unreliable network connections. [1] It runs at fixed bitrates of 3.2, 6, and 9 kbit/s and it is intended to provide better quality than codecs that use traditional waveform-based algorithms at similar bitrates.

3. JPEGmini - Wikipedia

   en.wikipedia.org/wiki/JPEGmini

   Video optimization: The release of JPEGmini 3.3 brought some additional feature of video optimization. Now it can reduce videos by up to 50% while maintaining original quality and playability. It also supports high bitrate videos, H.264/AVC and H.256/HEVC [7] video tracks, AAC audio tracks in MP4, M4V or MOV containers, with files up to 800 ...

4. Speex - Wikipedia

   en.wikipedia.org/wiki/Speex

   Speex is a lossy format, i.e. quality is permanently degraded to reduce file size. The Speex project was created on February 13, 2002. [ 9 ] The first development versions of Speex were released under LGPL license, but as of version 1.0 beta 1, Speex is released under Xiph's version of the (revised) BSD license. [ 10 ]

5. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.

6. List of open-source codecs - Wikipedia

   en.wikipedia.org/wiki/List_of_open-source_codecs

   This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.

7. Opus (audio format) - Wikipedia

   en.wikipedia.org/wiki/Opus_(audio_format)

   Possible bitrate and latency combinations compared with other audio formats. Opus supports constant and variable bitrate encoding from 6 kbit/s to 510 kbit/s (or up to 256 kbit/s per channel for multi-channel tracks), frame sizes from 2.5 ms to 60 ms, and five sampling rates from 8 kHz (with 4 kHz bandwidth) to 48 kHz (with 20 kHz bandwidth, the human hearing range).

9. FLAC - Wikipedia

   en.wikipedia.org/wiki/FLAC

   FLAC is specifically designed for efficient packing of audio data, unlike general-purpose lossless algorithms such as DEFLATE, which are used in ZIP and gzip. While ZIP may reduce the size of a CD-quality audio file by 10–20%, FLAC is able to reduce the size of audio data by 40–50% by taking advantage of the characteristics of audio.
