====== Analyser Development ======

//14 April 2002//

Although we are still working on the encrypted disk system, various things have been done to the [[:glossary:cta|analyser]] in the last few days.

  * Various generic processing speedups.
  * Analysation now supports a fast mode and a deep mode.

===== Fast Mode =====

There are various "escape points" where processing aborts the decoding of one specific [[:glossary:custom disk format|format]] (using the descriptor), and continues with the next one. In this mode, unknown or similar formats are usually not detected. Therefore selecting a format for a track that is not an exact match (taking into account any media errors) normally results in the format being rejected or a stream/recording format being selected. This new way of analysation is very fast, for example a dump of "Virus" analysed on a P3 450 setup is about 50 seconds compared to the original analysation taking 2.5 minutes.

===== Deep Mode =====

In deep mode the original analyzer behaviour is preserved that is able detect similarities with all the described formats.

===== Why =====

These changes are the side effect of some code reorganization needed for the encrypted disk system that is still being worked on, not just for the fun of it!
