WaveAlign
Aligns separately recorded audio to videos by waveform, fixes clock drift and exports via ffmpeg.
About
A Windows app drawn with MyGo's native UI that lines up audio from a recorder or mixer with one or more videos by waveform, corrects the clock drift between recorder and camera and detects reversed polarity. It lets you audition and nudge clips on a timeline, then exports through ffmpeg, copying the video stream without re-encoding and writing the new audio as AAC, PCM or FLAC.
