Simple ISP peak meter and few tests

This is simple inter-sample peaks (ISP) meter plugin. It is based on Limiter №6 ISP limiter true signal level detector in “precise” mode.

This is how it looks:

And these are test examples.

TEST#1. File with … 0 0 0 +1 +1 0 0 0 … impulse. It has calculated inter-sample peak value of +2.098 dB. My plugin shows +2.111 dB.

TEST#2. File with … 0 0 0 +1 -1 0 0 0 … impulse. It has calculated inter-sample peak value of +0.765 dB. My plugin shows +0.799 dB.

So, conclusion. My plugin has enough precision (greater than 0.1 dB) allowing its use to control inter-sample peak values. Also it can be used to control ISP modes in brickwall limiter plugins.

And as bonus there’re my calculations of theoretical peak values for both impulse files:
