  16. <p>&nbsp;</p>
  17. <p>Lame features some built-in presets. Those presets are designed to provide 
  18.   the highest possible quality.<br>
  19.   They have for the most part been subject to and tuned via rigorous listening 
  20.   tests to verify and achieve this objective. These are continually updated to 
  21.   coincide with the latest developments that occur and as a result should provide 
  22.   you with nearly the best quality currently possible from LAME.</p>
  23. <p><br>
  24.   If your goal is quality, these presets are highly recommended over any custom 
  25.   set of parameters you might use. To activate presets, you should use:<br>
  26.   <tt>lame --preset preset_name</tt><br>
  27.   <br>
  28.   <br>

  30. <h2>VBR modes</h2>
  31. <h3>--preset medium</h3>
  32. <p>This preset should provide near transparency to most people on most music.<br>
  33.   The resulting bitrate should be in the 150-180kbps range, according to music 
  34.   complexity.</p>
  35. <h3>--preset standard</h3>
  36. <p>This preset should generally be transparent to most people on most music and 
  37.   is already quite high in quality.<br>
  38.   The resulting bitrate should be in the 170-210kbps range, according to music 
  39.   complexity.</p>
  40. <h3>--preset extreme</h3>
  41. <p>If you have extremely good hearing and similar equipment, this preset will 
  42.   provide slightly higher quality than the &quot;standard&quot; mode.<br>
  43.   The resulting bitrate should be in the 200-240kbps range, according to music 
  44.   complexity.</p>
  45. <p>Any of those VBR presets can also be used in fast mode, using the new vbr algorithm. 
  46.   This mode is faster, but its quality could be a little lower. To enable the 
  47.   fast mode, use:<br>
  48.   <tt>lame --preset fast preset_name</tt></p>
  49. <p>&nbsp;</p>
  50. <h2>CBR 320kbps</h2>
  51. <h3>--preset insane</h3>
  52. <p>This preset will usually be overkill for most people and most situations, but 
  53.   if you must have the absolute highest quality with no regard to filesize, this 
  54.   is the way to go. This preset is the highest preset quality available.</p>
  55. <p>&nbsp;</p>
  56. <h2>ABR modes</h2>
  57. <h3>--preset &lt;kbps&gt;</h3>
  58. <p>Using this preset will usually give you good quality at a specified bitrate. 
  59.   Depending on the bitrate entered, this preset will determine the optimal settings 
  60.   for that particular situation.<br>
  61.   While this approach works, it is not nearly as flexible as VBR, and usually 
  62.   will not reach the same quality level as VBR at higher bitrates.<br>
  63.   If you need CBR encoding, those presets can also be used in CBR mode by using:<br>
  64.   <tt>lame --preset cbr &lt;kbps&gt;</tt></p>
