- In the editor, switch to “Toutes les options” (all options), then the “Photos” step.
- On the space you want, tap “Ajouter un commentaire audio” (add an audio commentary).
- “Enregistrer avec le micro” (record with the microphone): speak, then “Arrêter” (stop). Or “Choisir un fichier son” (choose a sound file): a voice memo from your phone (M4A) or an MP3, 15 MB at most.
- Listen, then “Garder ce commentaire” (keep this commentary). The space shows “Commentaire audio”; tap it to listen again, change or remove the sound.
- Publish or update the tour. The sound never starts on its own: the visitor chooses to listen, then the commentaries of the next spaces follow on; “Couper le son” (mute) stops them.
30 seconds to a minute per space: say what the photo doesn’t show (the aspect, the quiet, what has been redone, the story of the place).
