ARTA software is a collection of programs for audio measurements and analysis in acoustical and communication systems.
Dual-channel FTT-based analyzer for measuring the response of electrical or elctro-acoustic systems and viewing the frequency content of signals. Mostly useful for sound engineers. Rational Acoustics Smaart is a dual-channel, FFT-based acoustical analysis software application that runs on Microsoft Windows and Mac OS X. Oscilloscope is an open-source audio analyzer software that works as a real-time oscilloscope. This compact program enables the user to visualize the audio waveform by using the system sound card. It is a standard oscilloscope to analyze an audio signal. ARTA Software: Home Install Support FAQ Links: 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. Is an easy to use audio spectrum analyzer that allows you to view live audio in a standard frequency plot, a stereo oscilloscope view and a waterfall display. Powerful sound analyzer software.

ARTA software contains three programs:
ARTA.EXE - program for the impulse response measurement, real-time spectrum analysis and frequency response measurements.
STEPS.EXE - program for frequency response measurements with stepped-sine excitation.
Simultaneously with a frequency response measurement the program estimates levels of 2nd, 3rd, 4th, 5th and higher order harmonic distortions.
LIMP.EXE - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.
ARTA has functions of following measurement systems:
Signal generator of random and deterministic signals
Impulse response measurement system
Frequency response measurement system
Fourier analyzer
Spectrum analyzer
THD analyzer
Storage scope
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,
Octave SPL meter with noise rating (NR, NC, PNC, RC,NCB),
Third octave SPL meter with report of loudness in sones and level in phones
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.
