You can read ARTA as; Audio Real Time Analysis.
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.
