Hello

How to create video circular mask like diaphragm in superposition with video when sound is low high?

You're really asking several questions:

1. How to create a real-time mask
2. How create a geometric shape to use for the mask
3. How to get video to respond to audio

For 1., try looking at jit.lcd-layer.pat in the examples folder.

For 2., there are various options, but look into the LCD object or simply creating a JPG you use as the mask

For 3., lots of options. A quick/dirty approach is to use [meter~] chained to [zmap] then chained to whatever video parameter you want to modify.
