BRP-PACU(1)

✨ NAME ✨

brp-pacu 💖 dual fft live audio analysis program 🎀

Okay bestie, the name says it all: this is a dual FFT live audio analysis program 🦋 ngl the name alone is giving main character energy.

💅 SYNOPSIS 💅

brp-pacu

Literally just type brp-pacu and you're in. No fuss, no extra words, we love a minimal vibe 🫶

🌸 DESCRIPTION 🌸

okay so this manual page is a quick little intro to the brp-pacu program 🧚 It was written for the Debian distribution because the original program doesn't come with a manual page of its own, so somebody had to step up and be the hero 👑

brp-pacu is an audio analysis tool for configuring any sound system that has an equalizer ✨ It compares the output of your system to the input of your system, and then lets you use that data to do the final equalization by matching the results with actual DSP/EQ. It's giving precision, bestie 💜

Here's the setup, so pay attention 🙈

• Channel 1 is the output of the system you're observing. This is the measured signal.
• Channel 2 is the input. This is the reference signal.

You also need a decent, calibrated omnidirectional microphone 🎤 (reasonably flat from 20Hz to 20kHz, so it doesn't lie to you). Then you need 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. The laptop mic input is the sketchy one, so the pad is lowkey essential 💀

No pad is necessary if you're lucky enough to have a laptop or PC with a line input. Those people are eating ✨

The headphone out is where the pink noise comes out 🌈

brp-pacu works through the Jack Audio Connection Kit 🔥 so Jack has to be in the mix too.

🎀 OPTIONS 🎀

This program takes no arguments. Zero options, zero flags, zero drama 💅
