good afternoon brothers, I am developing a winamp-type program. My question is, how can I create a musical spectrum analyzer (vumeter)? They are like bars that move when they detect sound.

i use lazarus 32bits on win10 64bits
greetings brothers

Hello.

If you want a open-source solution, you may take a look at uos-consolespectrum demo:

Attached screenshot of StrumPract project that uses the uos spectrum-code.

The ACS audio package has code and demo's I believe that can do that.

Is on the OPM.
