How to configure lame in KDE4?

[Iker]

I would like to use lame the option set for V2? How to do this in KDE4? Actually I am too many doubts, since they are related to each other, I am posting in this same thread instead of making other. How can it seem as strange as VBR and ABR set a time? I have tried to change the settings in Control Panel but didn't succeed. The settings in the Control Panel are pretty confusing. In the lower third is in the title "variable bit rate" and below it are Average Bitrate "to click on and set the values". And what a Xing-brand? And lastly I want to know the difference between stereo, connected stereo and dual channel? I hope that you people will be kind enough to provide some help (like always).

Why up there are no numerical values, know only the makers of the board. The hook for "Average bitrate" must in any case be made out below if you want to have VBR. VBR means nothing other than that encoder for each block of data, these values may not even think of themselves. In the XING it is well within the actual playing time. VBR (Level III), one can no longer using the header and the file size even figure out how in the Level I (CBR) and Level II (ABR) still can. So definitely turn on, unless the player spits out looked as fire and brimstone.

As a joint stereo process (JS) are two algorithms described the case of digital audio compression techniques are used. Goal is to lower data rates while maintaining quality or higher quality at a sustained data rate. Both methods have their counterpart in the traditional sound - intensity stereophony and MS stereo - here called Intensity Stereo and Mid / Side Stereo. Only one of the two methods works without loss . Nevertheless, many users of the technology speak only of the joint-stereo methods, but mostly refer, of the lossless MS algorithm.

You should also know about the Intensity Stereo. This technique, which most encoders at very low data rates using only stores, only a single channel and direction information to reconstruct the stereo data. However, it will phase information is lost. The possibly occurring phase shift is above a certain frequency is no longer perceptible. Nonetheless, the original stereo information is lost, the process is lossy and is generally considered only for low data rates, where you take encoding mono rather have it a little stereo information. A lot will depend on the encoder selected data rate, whether intensity stereophony want to use, but there are some, mostly older codecs, exclusively on this technology.

The algorithm is very common for newer codecs and works without losses, which means that the available information, the original data (where the stereo channels) can be reconstructed bit by bit. Since experience says that even with stereo signals, a high correlation stereo channels present both, is the idea behind the coding, the average of the two stereo channels, one channel to be stored in (the mid channel, German as center channel) and the respective difference value in a different channel. Since the difference is very small or zero value is often in such information, the efficient matrix representation can be saved. It is applied among others in lossless audio codecs such as the open source codec FLAC , but even with lossy codecs such as LAME (the joint-stereo only MS stereo used for) for further quality loss greater compression without reaching.

However, arguments were at Intensity stereo and MS Stereo in a pot thrown, such as some of the unhappy union of the two techniques with a name based on have probably often. Meanwhile, the number of strict rejection of the algorithm seems fall, this is also due to more skilled in modern implementations of audio codecs. Especially in loss-free algorithms and at lower data rates, the technology is well established in practice. Absolute advantage is the consistent direction of dominance, it would appear when compressing two separate stereo channels, especially at low data rates, often as a problem because they felt there by a wandering of the stereo image of left and right makes. Joint stereo is encoded in the middle and side signal, here, this effect is as pulsation of the stereo width from center to the side, or is perceived just as significantly less intrusive than that the stereo center, the mainstream in the medial region 90% of all the important information has not clearly localized , or changes its position. Disadvantage is that in the event of a quiet side signal, such as in a reverberation room, the depth of field suffers from the sides. If the left and right channels differ greatly, MS-Stereo is also a deterioration compared to the separation by the conventional channels. Since the decision whether stereo is coded as a left / right or mid / side signal, in many audio formats for individual frames (sections over a few hundred milliseconds) can be taken to select encoder for such formats the presentation that can be encoded more if the user has not set a specific representation.
