Hello Everyone,

I started using ffmpeg to do some audio processing for one of my projects.

I wanted to know what the Peak level that is displayed as part of the
statistics indicates?

Example -
I ran the following command
                ffmpeg -i monoaudio.wav -t 10 -af astats -f null -

and one of the statistics is -
                [Parsed_astats_0 @ 0x2cca4e0] Peak level dB: -22.719262

Is this the peak level at the t mentioned or is it from 0...t (0 to t)?

Best Regards,
Balchander Ramachandran
