ffmpeg deessser on center channel (5.1)

[geextah_2]

Hi, I would like to apply a deesser on the center channel (5.1 layout) How do I achieve that?

This is my current profile

-af "pan=stereo|c0=c2+0.6*c0+0.6*c4+c3|c1=c2+0.6*c1+0.6*c5+c3" -map 0:v:0 -c:v copy -map 0:a:m:language:ger -codec:a ac3 -b:a 160k -ar 44100 -sn -dn

This is the deesser setting I would like to apply only to the center channel

-filter_complex "[1:a]deesser=i=0.7:f=0[a]"

From my understanding you cannot combine the -af (volume change) function with -filter_complex (deesser). So you would have to
1.export the center channel (mono).
2. Apply the deesser.
3. Merge the center channel back to 5.1 (I'm not sure if it's possible to swap out a single channel)
4. and than apply the -af volume change.

Any ideas how to make this more straightforward?

Thank you

You can use clever FFmpeg-GUI to convert your 5.1 file lossless to 6 single pcm (wav) files.

This is the answer provided by pandy, worked liked a charm

-filter_complex 'channelsplit=channel_layout=5.1[FL][FR][FC][LFE][BL][BR],[FC]deesser=i=0.7:f=0[FC_desss],[FL][FR][FC_desss][LFE][BL][BR]join=inputs=6:channel_layout=5.1:map=0.0-FL|1.0-FR|2.0-FC|3.0-LFE|4.0-BL|5.0-BR'
