This license item contains the Declipper, which restores distorted incoming audio, and Natural Dynamics, which pulls out the percussion instruments from the mix so they can be boosted separately to add more dynamics to the audio.

The Delossifier improves the sound of low bitrate MPEG (MPEG2, MP3) encoded files. It does two things:

• Reduce pre-ringing
• Fill up holes in the spectrum

The effect isn't a massive improvement, but it does make MPEG-compressed audio more listenable.

Advanced Dynamics is the difference between an "ok" sound and a great sound. It adds lots of features that improve the audio in subtle and sometimes less subtle ways.

• Adaptive Compressor mode
  The Adaptive Compressor mode is a fully dynamic, extremely powerful multiband compressor mode which eliminates the need for any other stages, includng an AGC.
• Auto EQ
  Adjusts the spectrum without using compression. Improves consistency with a much less compressed sound.
• Bass EQ
  Similar to Auto EQ, but specifiically for bass.
• Speech detection
  Disabling the bass enhancers and bass bands for speech makes speech sound much more natural, without affecting music.
• AGC upto 4 bands
  More fine control over the AGC behavior.
• Dynamic attack/release timing in AGC and all compressors
  The compressors dynamically adjust their speeds depending on incoming content. For very dynamic content they move faster, for already dense content they move slower. This also makes compression far less audible.
• Progressive ratios in all compressors
  Progessive ratios add more density for louder sounds - the compressors go down deeper if you add more audio volume. This, together with Progressive Release, is the "magic sause" that many processors use to create a "big" sound.
• Progressive release in all compressors
  If the compressors are pushed down a lot, they come back faster. This protects against "gaps" in the audio after a loud sound, and hence allows to set the normal release values much slower.
