I tried the Peak master and the results are the same as with UAD Precision limiter.
Not bad but not so good as when I reduce by hand the peaks and then raise the volume of the file.
Never mind, I’ll keep working as usually : working first with my analog chain with an analog limiter (Pendulum PL-2) before my A/D convertor and reducing the remaining peaks by hand in WL to get the extra dBs I need.
Anyway, thanks for your answers Phillippe.
