The conversational_speech_generator tool now adjusts the level of different speech segments. Implementation: The Turn and MultiEndCall::SpeakingTurn structs have an extra 'gain' member. It's read and parsed in timing.cc and put in a Turn struct. It's put in a SpeakingTurn struct in multiend_call.cc and read and applied to the signal in simulator.cc Bug: webrtc:7494 Change-Id: I9b82a896eb616c8b5ef14d41dfdfd085ef1d3fbb Reviewed-on: https://webrtc-review.googlesource.com/26280 Commit-Queue: Alex Loiko <aleloi@webrtc.org> Reviewed-by: Alessio Bazzica <alessiob@webrtc.org> Cr-Commit-Position: refs/heads/master@{#21714}
