Comment on attachment 133008 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=133008&action=review Xingnan, thanks for the patch.

Also, please make sure to call m_overlayBuffer.zero() in the reset() method... > Source/WebCore/platform/audio/DirectConvolver.cpp:74 > + float* outputBuffer = m_inputBuffer.data(); It might make sense to rename this member variable more generally now: m_inputBuffer -> m_buffer since it's a bit confusing to see line 74
