Sushi.net
Sushi.Net automatically shifts audio and subtitle tracks to help synchronize media playback.
About Sushi.net
Sushi.Net is an open-source tool that automatically shifts audio and subtitle tracks so that media from different releases of the same show or movie plays in sync. It matches a source stream against a destination stream and writes out a shifted version. The README says it is based on the original Sushi and uses similar command syntax, with the output parameter given as a path. It is a .NET 8 wrapper around Sushi.Net.Library, and the repository describes it as v1.0.0 and still beta.
FFmpeg and FFProbe are required. MKVExtract (for timecode extraction) and SCXvid (for keyframe creation) are optional. The README says the audio matching is accurate when the sources are of good quality. The repository lists Windows x64, Ubuntu x64, and OSX x64 binaries, although the platform field for this entry lists Windows only.
