I think this issue that comes up often is related to the restriction of uploading custom asset types directly. Webflow does not provide free CDN storage for unlimited file types. However, you can easily integrate audio if you use a third-party host or CDN to store the files.
HTML5 supports native playback of sound files with each browser, including support for different codecs. So in Webflow’s defense, why try to build something that already exists? In a rich text field, you can easily add media items.
Often missed is Webflow’s media embed functionality in RTE’s.

- Instagram post
- Facebook post
- Imgur albums
- Google maps
- Spotify playlists and charts
- And others…
