It was just an idea that I matured when I compared Shotcut’s loudness meter results with VST meters like Youlean Loudness Meter 2 or TBProAudio dpMeter IV (both free).
In those meters appear these values and I assumed (apparently wrongly) that these values were important for something.
My reasoning (surely wrong) is that since the monitoring of these values already exists, perhaps it was easy to establish a record of the maximum value they reach.
Maybe a checkbox (activation of maximum register) in the true peak value would be enough (I write from my ignorance of what involves the code so it is an absurd idea or very difficult implementation)
I’m still getting errors in dBTP. I managed to reproduce this in a project and upload it to the corresponding thread.
Thank you for answering.
