Wim Taymans 3496327e69 Add echo-cancel module ... Only implement the null echo cancel implementation for now. And skeleton webrtc echo cancel implementation It uses 4 streams arranged as: input ---+---> source ^ | sink ---+---> output The output of the source is the filtered input of the input stream (linked a master source) based on the data going from sink to the output (linked to a master sink). All streams are arranged in the same group so that the echo canceler does not have to deal with clock drift. For echo cancelers that can handle clock drift we might want place the source and sink chains in different groups.		2021-04-27 09:56:54 +02:00
