2. 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 ...

3. MP3 - Wikipedia

   en.wikipedia.org/wiki/MP3

   As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders do feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two early MP3 encoders set at about 128 kbit/s, [75] one scored 3.66 on a 1–5 scale, while the other scored only 2.22. Quality is ...

4. 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 ...

5. 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 ...

6. MediaHuman Audio Converter - Wikipedia

   en.wikipedia.org/wiki/MediaHuman_Audio_Converter

   MediaHuman Audio Converter is able to accept many popular audio file formats, such as MP3, WMA and WAV. The software is also capable of importing files to iTunes (Music app on macOS Catalina and above [4]). [5] MediaHuman Audio Converter is designed to use multiple CPU cores when converting files in ‘batch mode’. [6]

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).

8. Bit rate - Wikipedia

   en.wikipedia.org/wiki/Bit_rate

   In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. [1]The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). [2]

9. 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 ...
