How do I convert an AU file to MOV using LetsConvert?

Upload your .au (Sun/NeXT audio) file to LetsConvert. Choose MOV as the output, then click Convert. Once processed, download your .mov—the audio is wrapped in QuickTime's container with the sample rate and bitrate preserved. No extra software needed.

Why should I convert from AU to MOV instead of keeping the original?

AU is an uncompressed or lightly compressed audio format primarily used on old UNIX workstations, while MOV is a QuickTime container that supports advanced codecs like AAC and includes metadata. Converting to MOV makes files easier to edit in Final Cut, play in QuickTime, and share across modern apps without losing audio quality.

Does AU to MOV conversion preserve audio quality and metadata?

LetsConvert preserves the original sample rate, bit depth, and channel layout during the wrap to MOV. If the AU file contains PCM data, it's stored losslessly in the MOV container; compressed AU (like μ-law) is decoded and re-encoded to the selected MOV codec (e.g., AAC), which may introduce generation loss. Metadata tags are transcribed where possible.
