ACX Check Problem??

I analyzed a short sound clip and it passed ACX Check even though I believe the peak value is out of compliance (attached).

Every tool I have says the peak is -4.7 dB…

What tool do you have that says different?

I use an ACX peak range of -3.0dB to -3.5dB. The Normalize tool I recommend produces peaks at -3.2dB. There’s no reason to miss this spec. It’s not mysterious or fluffy and it’s dead easy to hit with graceful tools.

This clip was prepared with the processing tools out of order which can very easily produce a track on the edge of compliance — or miss them altogether, which I believe is the case.

As I read the document here:

https://www.acx.com/help/acx-audio-submission-requirements/201456300

It says “Each uploaded file must have peak values no higher than -3dB.” There is no “but at
least -3.5 dB” in that statement. I take it as a maximum only. They have the RMS level spec
to be sure that you are loud enough.
