Reason for revert: Because of down-stream dependencies, this CL needs to be reverted. The dependencies will be resolved and then the CL will be relanded. Original issue's description: > Revert "Revert of Moved ring-buffer related files from common_audio to audio_processing (patchset #8 id:150001 of https://codereview.webrtc.org/1846903004/ )" > > This reverts commit c54aad6ae07fe2a44a65be403386bd7d7d865e5b. > > BUG=webrtc:5724 > NOPRESUBMIT=true > > Committed: https://crrev.com/8864fe5e08f8d8711612526dee9a812adfcd3be1 > Cr-Commit-Position: refs/heads/master@{#12247} TBR=henrik.lundin@webrtc.org,ivoc@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
