  "message": "NetEq: Align correlation buffer size in Merge with DspHelper expectations\n\nThe peak-detection algorithm (`DspHelper::PeakDetection`) expects one\nextra element in the input buffer when `num_peaks \u003d\u003d 1` because the\nboundary parabolic fit algorithm may read index `data_length`.\n\nWhile `TimeStretch` allocated this extra element, `Merge` did not, which\nconstituted a minor API contract mismatch. Although this is mathematically\nunreachable in practice due to zero-initialization constraints in the\ncorrelation pipeline, we should align `Merge`\u0027s allocation with\n`DspHelper`\u0027s expectations to improve code consistency and readability.\n\nThis CL adds the `+1` safety margin to the correlation buffer allocation\nin `Merge` to match the pattern used in `TimeStretch`. We also modernize\nthe allocation to use std::vector for cleaner memory management.\n\nBUG\u003dNone\n\nChange-Id: Ie932dd298892bfba3b7c35f34e1774e13ecee34f\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/475001\nAuto-Submit: Henrik Lundin \u003chenrik.lundin@webrtc.org\u003e\nReviewed-by: Jakob Ivarsson‎ \u003cjakobi@webrtc.org\u003e\nCommit-Queue: Jakob Ivarsson‎ \u003cjakobi@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#47821}\n",
