Trouble keeping specific RMS and dbs max peaks

[Loussam]

So they asked me to export an audio file on stereo, keeping a max of 4dbs and 20 rms.
But when I change the rms the dbs change and the other way around.
For example, when I leave the rms at 20 the max dbs is -1.09 and when I let the max dbs the rms change to -22.1461
Is there a way to keep them both at the specific level that I need?

Thanks in advance.

I assume they mean -4dB. Most formats don’t go over 0dB and DACs don’t go over 0dB so 0dB should be considered the “digital maximum”.

But when I change the rms the dbs change and the other way around.
For example, when I leave the rms at 20 the max dbs is -1.09 and when I let the max dbs the rms change to -22.1461

Right. Any linear volume adjustment changes the peaks, RMS, and LUFS by the same amount. The difference is constant.

Is there a way to keep them both at the specific level that I need?

If you set the RMS level first, you can run the Limiter effect to bring-down the peaks, with very little effect on the RMS level.

Thank you so much! It worked wonders
