Be very clear all it does is tell you the technical specifications of your sound file and whether they make ACX compliance or not. It doesn't fix anything.
You can get one of them from me.http://kozco.com/tech/audacity/Document ... eck.ny.zip
Unzip it and drag acx-check.ny to the Audacity Plugins folder. ACX Check appears in the Analyze menu.
Select the whole show by clicking just above MUTE.
Analyze > ACX Check
There is a slightly different version in the Audacity libraries.http://wiki.audacityteam.org/w/images/5/53/Acx-check.ny
You don't have to unzip that one.
And there's yet another one in development.
