- dual fft live audio analysis program
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.
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.
works through Jack Audio Connection Kit.
