BRP-PACU Description

Open source and cross-platform professional sound analyzer BRP-PACU is a cross-platform dual channel FFT based Acoustic Analysis Tool to help engineers analyze live professional sound systems using the transfer function. One feature of BRP-PACU is the ability to capture four sample plots, average them, and invert to aid in final EQ.BRP-PACU is designed to be used with an omnidirectional calibrated microphone to configure any sound system with an appropriate equalization and delay. BRP-PACU compares the output of the system to the input of the system to obtain the transfer function of the system. These data allow one to perform final equalization using just the input/output of the DSP or any other device used for Equalization. Here are some key features of "BRP-PACU": · Four capture buffers · Averages buffers to a separate buffer and flips it for analysis · Automatic delay calculation · Impulse response capturing · Uses JACK to route and manage audio paths · Pink Noise generation tool to eliminate need for an external Pink Noise source Requirements: · GTK+ · Jack What's New in This Release: · Smaller screen sizes now supported · Octave based (log2) frequency grids instead of log10 · Auto-resize (ctrl-r) works much more predictably and smoothly · Delay size has been increased to 1000millisecs · Averaging (graph response time) and smoothing now adjustable via GUI · Other minor glitches fixed · Added Pink Noise Menu Item and CTRL-P accelerator · Major Performance improvement, more than halved needed CPU cycles in gui
