ARTA software is a collection of programs for audio measurements and analysis in acoustical and communication systems.
ARTA software uses standard and professional PC sound cards for audio signal acquisition and generation.
You can read ARTA as; Audio Real Time Analysis.
ARTA software contains three programs:
ARTA has functions of following measurement
Signal generator of random and deterministic signals
With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes:
Integrating SPL meter with 24 hours data logging,
ARTA is also a powerful analyzer of Gated impulse response, Smoothed frequency response (in 1/n-octave bands), Step response, Impulse response envelope (ETC – curve), Cumulative spectral decay waterfall graphs and sonogram, Burst decay waterfall graphs and sonograms, Energy decay in reverberant environments, Room acoustical parameters, Directivity patterns, Speech intelligibility measures: MTF, STI, STIPA, %AL.ARTA software contains User manuals for all its programs (see Install section).
Several Tutorials and Application Notes are presented in Support section.
April, 8, 2023; Last version of ARTA software compatible with Windows XP can be downloaded from Install section.News section.
