Hi Corona688...
Apologies for any typos...
Thanks for the heads up, you are a real pal...
I will fork the existing code and shorten it in your style but upload the longhand version for the foreseeable future.
I have done it this way so that a 10 year old can see the progression.
Does it show that much that I am an amateur... ;o)
BTW, calibrated timebase ranges are finished and coupling the earphone output to the mic input and setting the levels accordingly works a treat. Also added a small offset to ensure that the trace is linear when there is zero input. This removes the sound card's mid point bit error...
Working on a config file now so that user parameters can be saved and auto-restarted. This will take a while...
Bazza...

BRP-PACU(1) General Commands Manual BRP-PACU(1)
NAME
brp-pacu - dual fft live audio analysis program
SYNOPSIS
brp-pacu
DESCRIPTION
This manual page documents briefly the brp-pacu program. This manual page was written for the Debian distribution because the original
program does not have a manual page.
brp-pacu is an audio analysis tool to configure any sound system with an equalizer. It compares the output of the system to the input of
the system and allows you to use this data to perform final equalization by matching the results with actual DSP/EQ.
Channel 1 is the output of the system we are observing (measured), channel 2 is the input (reference). You also need a decent calibrated
omnidrectional microphone (reasonably flat 20Hz-20kHz) and either a USB-Preamp like the 2-channel M-Audio, or a mixer with a 30dB pad or so
going into the laptop mic input. No Pad is necessary if you are lucky enough to have a laptop or PC with a line input. The headphone out
will have the pink noise.
brp-pacu works through Jack Audio Connection Kit.
OPTIONS
This program takes no arguments
