Il y a une dimension malmenée, il faut revenir à la théorie, parfois, traiter le problème, puis écouter,
en plus ça ne coûte pratiquement rien*!

"4. PERCEPTION OF CROSSOVER PHASE
AND GROUP DELAY CORRECTIONS
A listening test has been carried out in order to
understand the phenomenon of phase and group delay
distortions. The test simply comprised listening to a
music track 2 minutes long, first without correction;
then a second time with crossover group delay and
phase corrections.
The results were extremely impressive for all listeners.
The majority of them have noted that the corrected track
presented greater sound clarity, a more spacious and
detailed sound environment, as well as best stage
localisation."

du 50 Hz rapide, c'est quoi? du 51 Hz ? ou plus ?
