I am trying to format mp3 audio files to ACX standards. all I get is ' the file is not suitable for ACX export. what are the requirements for the basic file?
The above response does not answer the question. The ACX Export function is supposed to format a file to the specs mentioned above. When the export process has an issue with an input file, the only feedback you get is " the file is not suitable for ACX export". There is nothing that tells you what the issue is or how to address it. I need to know how to troubleshoot this issue. I have already spent many hours trying to guess what is wrong so I can get my chapters processed. I believe this is a SoundForge issue and needs to be addressed.

The ACX Check tool tells you all you need to know about what is wrong with the audio file - see image below.
This issues is not about the ACX statistics or ACX Check. It is regarding the ACX Export functionality, which I use regularly. My understanding of the ACX Export function is that it prepares/formats a raw wave file into an MP3 file properly formatted for the ACX Web site. When completed it passes the ACX Check. Intermittently, about one in three WAV files fail this process on my current project. The only error message I get is "The Dynamics of the file are not suited for ACX Export" (see file below). I get no other indication as to what is wrong in the file or how to fix it. ACX Check will not resolve this because all the files I get are not initially formatted for ACX. I need to know what is happening inside the ACX Export process so I can resolve the file issues and complete my current project. I hope this clarifies the issue more appropriately,
@Thomas-Braun3542 As I see it, you need to edit your file manually depending on what you see in the ACX check.
if your file is too loud, you need to reduce the volume manually. If it's too quiet you need to raise the volume manually. If the background nose it too loud, you need to do noise reduction manually.
I suspect that ACX export will work fine as soon as all ACX check properties are in the green.
By the looks of your screenshot's amplitude @Thomas-Braun3542, it is way too loud. Use the Sound Forge 'Statistics' tool to determine the RMS loudness factor and reduce the level accordingly. If you can post the file on google drive or other cloud site, we could determine a more exact procedure for ACX compliance .
