The click scanning options have been revised and expanded.. This gives additional scanning and correction options for advanced users.
The signature line is now displayed in the main window as well as the overview window.  This permits clusters of corrections to be identified more easily.
The graphic equaliser has been considerably enhanced. There is now the option to expand the bottom 10% of the frequency range and the filter can now be configured with the keyboard as well as the mouse. The filter also now correctly takes account of the sampling rate and adjusts itself accordingly.
In spectrum view, the frequency scale is annotated with values, scaled for 44.1 and 48kHz sampling as appropriate.
Maximum width corrections are now always given a magnitude greater than 30
Minimising is now possible during loading and recording.
A new Cancel Block command has been added.

8th November 2004 Version 3.1 released
Changes Version 3.1 from Version 3.0
You can now use an external command line encoder as an alternative to the built-in ogg and ape encoders. This will most likely be used with the popular  mp3 encoder lame.exe although other command line encoders can also be used if desired.
The Batch processing window now has an additional 'scale' option. This enables you to apply a selectable amount of gain (or loss) to all the files being batch processed.
When clusters of click corrections overlap, they are now processed  in the order of their severity ranking. This  overcomes a problem when editing corrections in such circumstances. In previous versions, edits were not always preserved after the 'Apply' button was selected.
Various improvements have been made to the Record dialog. These include the addition of Windows mnemonics and ToolTips; the option to select a stop time instead of a duration; the option to auto-start a recording; the recording directory is now saved to the registry for persistence; the record meter now removes dc offset at low volume levels
The program now checks disk space before recording and sets a maximum recording time accordingly.
The batch dialog now shows the click count after click detection and  the maximum amplitude when normalising.
The tracks menu now allows up to 500 tracks to be listed.
There is  a new link on the Help menu direct to the support section of the Wave Corrector website.
There is a relaxation of the limitations in the trial version. The program now saves the first and last 30 seconds of tracks after track 1. This enables the full trialling of track editing features.
Some minor modifications have been made for improved Linux compatibility.
Bug fixes: 
when tokens were used in file naming, only one  directory  could be created in a nested chain. This restriction has been fixed.
A problem associated with the horizontal scale have been fixed. The bug caused an incorrect scale setting to be used when a file was loaded after a previous file had been closed.
Restoring a session file now works when the original file is in .ape format.
Changes between record sample rates of 44.1 and 48kHz are now applied immediately
The temp and output paths are now set correctly when a root directory is selected.

0 8th March 2004 Version 3.0 released
1 Changes Version 3.0 from Version 2.5
The program now supports saving and loading in Monkey's Audio .ape format as well as saving in Ogg Vorbis .ogg format. Both compressors can be configured to meet user preferences 
Files can now be tagged with the following additional information: Track Title; Track Artist; Album Title and Genre. This is to permit easy integration with a PC music library. Tags are saved in ape files, ogg files and Wave Corrector session files. 
The program now supports a sampling rate of 48kHz as well as 44.1kHz. 48kHz is the native sampling rate of most PC soundcards as well as DAT and most digital broadcasts. Using 48kHz sampling will sometimes allow you to avoid unnecessary sample rate conversions. 
Files names can now be specified as any combination of the input file name, track tags, track numbers and user entered text.  
There is now an option to slow down playback speed to aid the identification of clicks.
Timed recordings are no longer restricted to one hour and are allowed up to the maximum permitted by Wave Corrector's internal format (3hrs 22 min at 44.1kHz sampling).

It is now possible to specify a default output directory for saving files. 
It is now possible to select an input or output device from within Wave Corrector and to select an alternative record Volume Control if one is supplied with your soundcard. 
The limitations in the demo version have been relaxed. All tracks can now be saved although there is a 30 second limit on tracks after track 1. 
A new command, 'Shrink Correction', has been added. 
Various keyboard shortcuts have been added.
Vertical and horizontal scale settings are now saved in the session file.
The playback routines have been modified to ensure better synchronisation with some soundcards.
Visibility of the moving playback cursor in the main window has been improved.
