Tunebite High-Speed Dubbing is a feature associated with Tunebite, a software tool designed to help users convert and record audio and video files, particularly from DRM-protected sources. Tunebite (now known as Audials Tunebite) can be used to bypass certain restrictions placed on digital media (like DRM) and convert it to more accessible formats. The "High-Speed Dubbing" feature typically refers to the ability to convert or record media content at a faster-than-real-time speed, which is useful for efficiently transferring large amounts of audio or video.
