2. Comparison of audio coding formats - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_audio_coding...

   For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...

3. Advanced Audio Coding - Wikipedia

   en.wikipedia.org/wiki/Advanced_Audio_Coding

   Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO / IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio). Improvements include: more sample rates (from 8 to 96 kHz) than MP3 (16 to 48 kHz); up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and ...

4. 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).

5. Vorbis - Wikipedia

   en.wikipedia.org/wiki/Vorbis

   Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder (codec) for lossy audio compression, libvorbis. [10] Vorbis is most commonly used in conjunction with the Ogg container format [11] and it is therefore often referred to as Ogg ...

6. High-Efficiency Advanced Audio Coding - Wikipedia

   en.wikipedia.org/wiki/High-Efficiency_Advanced...

   Evolution from MPEG-2 AAC-LC (Low Complexity) Profile and MPEG-4 AAC-LC Object Type to HE-AAC v2 Profile. [2] High-Efficiency Advanced Audio Coding (HE-AAC) is an audio coding format for lossy data compression of digital audio defined as an MPEG-4 Audio profile in ISO / IEC 14496–3. It is an extension of Low Complexity AAC (AAC-LC) optimized ...

7. Data-rate units - Wikipedia

   en.wikipedia.org/wiki/Data-rate_units

   The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

8. Musepack - Wikipedia

   en.wikipedia.org/wiki/Musepack

   Musepack or MPC is an open source lossy audio codec, specifically optimized for transparent compression of stereo audio at bitrates of 160–180 (manual set allows bitrates up to 320) kbit/s. It was formerly known as MPEGplus, MPEG+ or MP+. Development of MPC was initiated in 1997 by Andree Buschmann and later assumed by Frank Klemm, and as of ...

9. ATRAC - Wikipedia

   en.wikipedia.org/wiki/ATRAC

   SonicStage version 3.4, released in February 2006, [14] introduced ripping CDs in bitrates 320 and 352. [15] The available bitrates are: 48, 64, 96, 128, 160, 192, 256, 320 and 352 kbit/s. The newer bitrates are not always compatible with all older hardware decoders, however, some of the older hardware has been found to be compatible with ...
