How to upload a session's audio
Updated on May 18, 2026
Uploading the audio
- Open the session (or create a new one).
- Click Upload audio.
- Select the file and wait for the upload to finish.
Formats and size
Tessel accepts the most common audio formats. Very long files are automatically split into parts before transcription.
What happens next
Transcription runs in the background and consumes credits based on the audio length. You can follow the progress in the session itself and are notified when it's done.
If processing fails, see audio upload problems.
