CVU to SNDR conversion is the process of transforming audio files encoded in the CVU (Custom Vector/Ultrasonic) container into the SNDR (Sound Descriptor) format. This conversion repackages and, when necessary, re-encodes audio streams and metadata so they play back correctly in applications and devices that require the SNDR specification.
