Detect tempo/bpm of audio files [closed]

I'm a php developer who is developing an app that works with audio files. I would love to have a mechanism to detect the tempo/bpm of an audio file (mp3, wav).

I can't find any library, API or tutorial about this task, it looks very challenging. All I've found has been very old posts and documents (more than 10 years ago) that looks so outdated.

So, I come here to ask about this. Do you know a way to detect the tempo/bpm of an audio file? Or an API I could use?

I need a programmatic solution without using an external program or web app if possible.

Thanks!
