This is a reland of 81c0cf287c8514cb1cd6f3baca484d668c6eb128 Original change's description: > Simplification and refactoring of the AudioBuffer code > > This CL performs a major refactoring and simplification > of the AudioBuffer code that. > -Removes 7 of the 9 internal buffers of the AudioBuffer. > -Avoids the implicit copying required to keep the > internal buffers in sync. > -Removes all code relating to handling of fixed-point > sample data in the AudioBuffer. > -Changes the naming of the class methods to reflect > that only floating point is handled. > -Corrects some bugs in the code. > -Extends the handling of internal downmixing to be > more generic. > > Bug: webrtc:10882 > Change-Id: I12c8af156fbe366b154744a0a1b3d926bf7be572 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/149828 > Commit-Queue: Per Åhgren <peah@webrtc.org> > Reviewed-by: Gustaf Ullberg <gustaf@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#28928} Bug: webrtc:10882 Change-Id: I2ddf327e80a03468c41662ae63c619ff34f2363a Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/150101 Commit-Queue: Per Åhgren <peah@webrtc.org> Reviewed-by: Gustaf Ullberg <gustaf@webrtc.org> Cr-Commit-Position: refs/heads/master@{#28938}
