+<br>
+The sound quality of MP3 files is influenced primarily by the chosen bitrate (ABR/CBR mode) or by the chosen<br>
+VBR quality level. These options control the "file size -vs- quality" trade-off. That means, you can get a<br>
+better quality at the cost of a bigger file (increased bitrate); or you can get a smaller file at the cost of<br>
+reduced sound quality (decreased bitrate). The "algorithm quality" is yet another way to control the quality.<br>
+<br>
+While the chosen bitrate (or VBR level) influences the resulting bitrate, the algorithm quality does not!<br>
+Instead, the algorithm quality controls the "encoding speed -vs- quality" trade-off. That means, you can get<br>
+a better sound quality at the cost of increased encoding time (higher algorithm quality); or you can get a<br>
+faster encoding speed at the cost of reduced sound quality (lower algorithm quality). Note that while the<br>
+algorithm quality does influence the encoding speed, it does NOT influence the decoding speed at all. Also<br>
+note, again, that the chosen algorithm quality does NOT influence the resulting file size at all.<br>
+<br>
+The LAME algorithm quality is an integral value between "0" (best/slowest) and "9" (worst/fastest), but NOT<br>
+all possible values will currently have a distinct effect! More specifically, the following table applies:<br>
+<br>
+For CBR and ARB modes:<ul>
+<li>0: Use slowest &amp; best possible version of all algorithms
+<li>3: Default value, good speed, good quality
+<li>7: Very fast, ok quality (psycho acoustics are used for pre-echo &amp; M/S, but NO noise shaping)
+<li>9: Disables almost all algorithms including psy-model, poor quality</ul>
+For (new) VBR mode only:<ul>
+<li>0 to 4: Use the best algorithm (slower)
+<li>5 to 9: Use the not so good algorithm (faster)</ul>
+<br>
+The "algorithm quality" options available in LameXP will be mapped to "0", "3", "7" and "9", respecitly. Note<br>
+that option "0" (best quality) is only very slightly better than "3" (high quality), but significant slower!<br><br>

LAME v3.99 contains the latest improvements and bugfixes of the LAME mp3 encoder, but it's less tested than<br>
the older 3.98 release series. The most important reason why LAME v3.99 is used in LameXP v4.xx is because<br>
