I’m in trial mode for POWAIR, and using a spectrum analyzer to examine POWAIR’s effect on the spectral balance to better understand how the features interact with each other. I’m stumped by the “Punch” control. As far as my ears and spectrum analyzer can discern, there is absolutely no real difference between the Attack and Punch controls in POWAIR. It’s as if the Punch is doing -exactly- the same thing as the Attack.
I’ve tested this scenario with the SCF on and off (and at different filter ranges) , and with the Leveler on and off. Same results every time.
For example, set Attack to 0 ms and Punch to 100% and take a snapshot of the spectral curve. Then set Attack to 100 ms and Punch to 0% and you get an -exact- match to the snapshot, both in the Peak curve and in the Average RMS curve. This indicates -exactly- the same spectral balance between those two different settings (and my ears agree).
Which implies that the “Punch” slider is essentially doing exactly the same thing as the “Attack” slider, and that whichever setting is more extreme will essentially override the other setting. Which makes it much less intuitive and rational to decide where to set either of those settings.
Can you explain in more detail how, exactly, the Punch feature is operating and why it’s different (and should have a slightly different outcome) than the Attack setting? And yes, I’ve read the entire manual and it implied that the Punch control should be acting different than I’m seeing/hearing. The manual and your videos imply that the Punch feature should just be doing independent clipping of the transient peaks, probably with a small degree of oversampling lookahead? (instead of compressing the peak and everything near it).
