I've been stumped in trying to use the EAC WAV editor. I go to Tools/Process WAV and a window opens which allows me to locate the file I want to edit. However, after I select the file nothing else happens.
EAC will only process 44.1kHz stereo files, but it should give a warning pointing this out if you try and open a file in the wrong format.
I've just been trying out the recent beta5 release, and the wave processor works OK for me.
