Matrix formats - declick before or after decoding?

[Colin Dunn]

I've been wondering ... is it best to de-click before or after decoding SQ/QS into 4 discrete channels?

Before pros: A cleaner source file that can be reused as decoding scripts / techniques improve. Only have to remove noise from 2 channels instead of 4, saving time.

After pros: De-clicking before may do strange things to the phase encoding for matrix surround. It's may be better to decode something minimally altered and then process in later stages.

De-clicking before decoding is fine

I do both. There's always a bunch more clicks to remove after decoding even if I declicked before decoding, especially in the rears.
