1. The following actions can be performed on pet cloud-stored audio files: retrieve all cloud-stored audio, preview cloud-stored audio, add new cloud-stored audio, download cloud-stored audio to devices, and delete cloud-stored audio.

2. Editing pet cloud-stored audio files mainly relies on the following 4 key capabilities:

- **Retrieve Pet Media Files**  
   Developers can use the [fetchPetAudios](/en/miniapp/develop/ray/api/ai/aiPet/pet_media-device/fetchPetAudios) API to retrieve pet media files.

- **Download Pet Media Files**  
   Developers can use the [notifyDownload](/en/miniapp/develop/ray/api/ai/aiPet/pet_media-device/notifyDownload) API to download pet media files to devices.

- **Delete Pet Media Files**  
   Developers can use the [deleteDeviceFile](/en/miniapp/develop/ray/api/ai/aiPet/pet_media-device/deleteDeviceFile) API to delete pet media files.

- **Music Resource Control Instance**  
   Developers can use the [createInnerAudioContext](https://developer.tuya.com/cn/miniapp/develop/ray/api/media/audio/createInnerAudioContext) API to preview cloud-stored audio files.
