Thanks steve, but I'd like to ask about the recommend settings of the 
compressor, the  plugin included in current audacity.

  With Chris's Dynamic Compressor version 1.2.6 I'd suggest trying:

  For Classical music and similar, everything at the default values
  except for "Compress Ratio" (the first control). Try setting Compress
  Ratio to about 0.7

  For speech and other material, try setting Compress  Ratio at around
  0.8  and set ."Compression Hardness" (the second control) to 0.7.

  The first control (Ratio), sets how "strong" the effect is. At 0.5 it
  is very mild and at 1.0 it is very strong. The "stronger" this setting
  the more it will amplify the quiet bits. At a setting of 1 it will try
  to make everything the same volume.

  The second control (hardness) sets how fast/aggressive the effect is.
  At 0.5 it will adjust the volume slowly, taking several seconds to
  raise the level of quiet parts. This will usually suit sounds that
  vary in loudness quite slowly, such as much classical music. When set
  to 0.7 or above, the effect will react much more quickly, but if it is
  set too high you will notice a kind of "pumping" of background noise.

  There is also some information about usage above the controls. I think
  that screen readers should be able to read this, but please let me
  know if they don't. The text above the controls says:

  "Does dynamic (volume) compression with lookahead. Compress ratio' is
  how much compression to apply. Raise when soft parts  are too soft,
  and lower to keep some dynamic range. You can soften the  soft parts
  instead of increasing them with values < 0, and invert  loudness with
  values > 1 (lower max amp when you do). 'Hardness' is how agressively
  to compress. Raise when parts are still  hard to hear (even with a
  high compress ratio). Lower when the result  sounds distorted. Raise
  'floor' to make quiet parts stay quiet. Raise 'noise gate falloff' to
  make quiet parts (beneath 'floor') disappear. Lower 'maximum
  amplitude' if you experience clipping."
