Detecting beats in a song

I'm working on a project which requires me to add beat detection when a song is playing in the application (WinForms - C#).

I'm currently using NAudio.NET for playing the song & displaying details about the song.

Is there a library that would allow me to do this or some way to detecting this manually? I'm not expecting a finished solution but pointers in the right direction. Ideally I would like this to be a real-time detection but it is not essential.

What is automatic beat detection?

Automatic Beat Detection is used to identify the best sample position of the repetitive beat pattern found in an audio file, the final beats are determined via a search of all possible combinations of phase and frequency to find maximum correlation between theoretical beats and observed.

Does Premiere Pro have beat detection?

BeatEdit detects the beats of your music and represents them as markers in the Premiere Pro timeline. Use the beat information to generate fully automatic edits in sync with the music. If you need more control, the beat markers can also be used as guides in your manual editing process.

How do you use beat detection in Filmora?

Right-click on a music file that you want to detect the beats for. You can choose from the built-in music or your imported audio files. Select Beat Detection in the context menu. A Beat icon will appear on the music's thumbnail when the analysis is finished.

You can use this BPM Detection Library

Besides BPM calculation it also allows you to get every beat, so you could for example adjust your visualisation, if that is the case.
