Yes! Use our editor to add [music], [laughter], and other non-speech descriptions for full accessibility.

Absolutely! Captions make your video content searchable and improve accessibility, both of which can boost SEO rankings.

Not directly — MUS files contain music notation data rather than recorded audio, so there is no spoken content to transcribe from the file itself. If your project includes recorded audio, export it from Finale as a WAV or MP3, then upload that audio file to transcribe it, edit the transcript, and export the text.

MUS is a notation document, not an audio file, so media players have no audio stream to decode. Open it in Finale and use the software's audio export if you need a playable file.

MUS is a proprietary Finale format, so most other applications cannot open it directly. Exporting the score from Finale to MusicXML is the standard way to move it into other notation software.
