Gain Reduction Meter Help (IPlug)

[tunca]

I'm tring to use vu meter as gain reduction meter.Used vu meter from MultiTarget example.

As vu meter,it's working good.But not as gr meter.

My gr meter working like this; "in - out".Just simple idea.It's working but if input signal is low level,meter doesn't work properly.

For example when input level around 0 dB with -6 dB reduction,meter shows reduction properly.But when input level around -6 dB with -6 dB reduction,meter shows 2 dB or less reduction.So when input signal low,gr meter not showing correctly...

What is your method?Are you using simple meter example or another one?

I really need help about that.

Thanks.

Use the GR sidechain instead of the in/out ratio. That would be whatever scalar is modifying the output signal. If your SC is more complex than this, you can still use it, with appropriate transfer functions.

But for a simple solution using in/out ratio, you must have an envelope of both, then divide the output by input, taking precautions to not divide by zero.

Thanks for reply.

I used envelope for in and out and than divide output by input,it's working good!

Thanks!
