Convolution Filtering
Hi,
On Saturday I measured my room using Dirac and so know where I am having a couple of issues, at 27Hz and 37Hz, the former needing reducing, the latter a gain. I thought I would try using Convolution to address these and came up with this statement: convOut= -lavfi "equalizer=f=27:width_type=q:width=8:g=-1.46,equalizer=f=37:width_type=q:width=8:g=2.04" Which appears to be working OK .....BUT, the FFMPEG help file mentions several times: 'Beware of clipping when using a positive gain', which I am at 37Hz. How do I check for clipping, or is there a way to apply gain without going into clipping? Thx. |
