[Mr Artichaut]

Thank you, I will do that.

How do I know which input is required when reading from the sink ? Because
it is after the amix filter, my sink only has one input.

I was doing that because my inputs will always be small audio files (less
than 20s) ans there will never be more than 3 of them.
