This article is a stub. You can help the Hydrogenaudio Knowledgebase by expanding it.
This is a guideline. Please use it for creating articles in this wiki.
The aim of this guideline is to provide ways to standardize articles in this wiki. Every article should abide to the general structure below:
Introduction ==Lead section #1== This is the lead section of the article. ===Subsection #1.1=== This is a subsection of the article. ====Subsection #1.2==== This is a sub-subsection of the article. ==Lead section #2== This is the lead section of the article. ===Subsection #2.1=== This is a subsection of the article. ====Subsection #2.2==== This is a sub-subsection of the article. ==See also== See also section. ==Notes and references== Notes and references section. ==Further reading and bibliography== Reading and bibliography section. ==External links== External links section.
Introduction
Every article should start with a summary of the topic detailed in the article. This is the very first thing to be written before any section.
Example:
|
'''Joint stereo''' coding methods try to increase the coding efficiency when encoding stereo signals by exploiting commonalties between the left and right channel signal. |
Lead sections
An article may have any number or lead sections. Within these sections you should put any relevant information about the section topic including pictures, media files, formulas etc.
Example:
|
==Additional information== Some more details, history and examples about joint stereo & mid/side coding: mid/side can be lossless like obviously in Lossless formats Flac, Wavpack, Monkey's Audio (ape) etc., but in lossy encoders the encoder tries to do the best to minimize all losses in perception. And here the encoder has not only to deal with stereo modes, but also with mids, highs etc. etc. So, regarding lossy formats like MP3 (Lame, Fraunhofer, Xing), Musepack (MPC), Vorbis etc., the mid/side coding might be even mathematical lossless, might be perceptual lossless (=transparent), or not so lossless at all at low bitrates. So, it depends in the lossy formats about the quality of mid/side (js) coding. From obvious bad sounding bugs like in some old Fraunhofer mp3 ("Radium hack"), not so optimized perfomance like in mp3-Xing, up to the optimized js-modes in mp3-Lame, which offer frame-dependent stereo or mid/side coding to achieve maximum qualities. And advanced formats like mp3-lame, Musepack-MPC or Vorbis-ogg offer increasing js(mid/side//stereo)qualities in increasing general quality (q) levels, examples: Mp3-Lame inside the presets eg. -V quality levels, with different -msfix values up to the "nssafejoint" mode in 320 kbit cbr. Musepack-MPC inside the various q-levels/presets and the --ms x switch. Vorbis in its presets, 1 example above q6 the "lossless stereo coupling". |
