X/RTA Audio Real Time Analyzer for X
Version 0.30 of X/RTA is now available. Changes is this version
include code optimization and the addition of sixth octave analysis,
plus various bug fixes.
X/RTA is a constant percentage bandwidth real time analyzer for acoustical
measurements. It uses digital filters to do octave band and fractional
octave band filtering of the audio spectrum.
The signal processing unit is written in C. The interface is written
in Tcl/Tk, with the Blt toolkit. As Tcl is a scripting language, this
makes the creation of sequences of tests straightforward.
In its current state, with X/RTA you can perform octave, third octave,
and sixth octave analysis with A and C-weighted SPL, save and recall data files,
and print data (using gs or ghostview). Thus you can measure and tune
a home theatre, commercial cinema, hi-fi, public address system, etc.
REQUIREMENTS
Linux x86, 2.xx
Pentium 133 or better
sound card capable of sampling at 48 kHz
