How to add Audio to your NFTs

In this guide, we will look into how you can add an audio or multiple audio files to your NFTs. Note that adding the audio will happen during the creation of the token-type (NFT template).

📘
You need to have the URL of the audio address that you wish to add. When you still need to upload your media, then learn how to store your media/images on Venly Servers.
