PureBasic Forums - English

Does anyone know how to write a VU meter in Linux? It doesn't need to do much, simply watch the sound input and output and show signal strength. I don't need a graphical component at this point, just a simple program that will watch the audio and give me some kind of numbers.

Thanks

Through ALSA this is quite easy. I don't have code right now, but the project Kamix might be interesting: http://kamix.sourceforge.net/

If you are familiar with C, you could try to sneak out the VU Meter code and convert that to PureBasic.
Also, if you have ever heard of GKrellM, there is a plugin for it to display a VU Meter which might also interest you: http://freshmeat.net/projects/gkrellmss/

Again, if you are familiar with C, you could try to sneak out the code you need. But be careful of licenses when you sneak code out.

Good luck.
