Recover lost Audio files Android 8.1, How can I do it?

Placing a request by someone in a chat group here.

Trying to recover lost audio files on my Android 8.1. any recommended softwares…, must I root my device?

Which software can I use to recover deleted audio files from Android 8.1? Will really appreciate feedback, I am stuck.

I came across a blog that had steps mentioned on how to recover. I cant post the link to the blog here for some reason, so I am clueless on how to share that resource here.

The reason is your urge to promote some vpn in the past.
