Can you down this small (4.6MB) AC3 file.
https://www.mediafire.com/file/svg2n...nwf/A.AC3/file
and try again with the convert whotsit,
copy into the CONVERT folder, and
Double click "AC3_To_THD.BAT", output will be in OUTPUT folder.
Works here with exact same CONVERT folder upped to Mediafire several posts ago.
Source file was just 60 secs of mp3 podcast talking converted to AC3.

Maybe I should have used (or converted to) AC3 to 48000Hz.
Anyways, it does convert whether complies with any kind of spec of not.
