Vu Meter

is possible to make a vu meter in sonicbirth? and how? thanks

Well, you could certainly do the necessary math in Sonic Birth to get the RMS value of the waveform using an absolute value function (or the square root of the waveform squared). And then you could low pass filter. It would be a lot like making a custom envelope follower for a compressor circuit. That part is totally possible.

But to display it as a meter . . . you would have to use one of those few bar-type display elements provided in Sonic Birth. You aren't going to get the nice VU needle display.

So you could get the output you want but just not display it the way you might want.

Although now that SB is open source, if some brave soul wanted to delve a little into the backend Code and create an analog needle module it could be done.

you can still mimic a digital VU "needle", like a dorrough 40 display, if you craft yourself a background, and then make the level meters transparent on solid background (instead of vice versa). to do the latter, check "inversed", then set min to 1, max to 0, then make the first colour transparent, and set the last colour to the colour of your background (i.e. black?)... try it out ;)

here's a sample meter i put together while learning sonicbirth.. (sonicbirth file, skin, and au component included)
it's by no means accurate, but feel free to hack in a proper circuit..

Nice

fantastic... thanks

that is a very creative usage of available components!
