[FFmpeg-user] “Brick wall” high pass filter

[Benjamin Houtman]

Hi all,
I’m attempting to create a high pass filter that removes all frequencies
below 50 Hz. I’ve tried acutsub, acrossover, and highpass, but they all
seem to attenuate rather than remove those tones entirely. I need to do
these in batch on multiple files so a DAW really isn’t an option. My
apologies, but I’ve tried multiple commands so I don’t know that i could
post them all here. Please advise.
Best,
Ben
