Equalizer by left and right channel
Maybe this question has been asked previously. But can someone share the setup for equalization applied for each channel (left and right speakers). Thanks.

Currently I am using a single equalization setup (e.g convOut=-af "equalizer=f=141:width_type=q:width=28.4:g=-2.3, equalizer=f=150:width_type=q:width=37.1:g=-3.1")
Thanks

RE: Equalizer by left and right channel
A quick web search found this thread showing how asplit and amerge can be used to apply different settings to different channels. I haven't tried this myself.

Thanks Simon. I did see this thread but not sure how to write the full syntax with equalizer config. Anyway, I gave convolution (exporting filters as wav file in REW) a go and it seems to work. Hope it does not reduce the dynamics which convolution method sometime cause as a negative impact.

RE: Equalizer by left and right channel
Hi, I found the ffpmped to equalize by channel - sharing in case anyone is looking for the solution.
convOut=-af " equalizer=f=1037:t=q:w=4.9:g=-3.4:c=1, equalizer=f=182:t=q:w=32.1:g=-3:c=2, equalizer=f=192:t=q:w=27.2:g=-6.5:c=2, equalizer=f=1114:t=q:w=5:g=-1:c=2 "

Thanks for posting this. It looks like c=1 and c=2 are the settings needed for stereo equalization.
