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.
