ARTA software is a collection of programs for audio measurements and analysis in acoustical and communication systems.
It consists of following programs:
ARTA - program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements.
STEPS - program for frequency response measurements with stepped-sine excitation.
LIMP - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.
This program has functions of following measurement systems:
Impulse response measurement system with signal generators: periodic white noise, periodic pink noise, MLS, linear and logarithmic swept-sine.
Dual channel Fourier analyzer with signal generators: white noise, pink noise, periodic white noise and periodic pink noise.
Single channel Fourier analyzer with signal generators: periodic white noise and periodic pink noise.
Spectrum, octave band and THD analyzer with signal generators: sine, two sine, multitone, white noise, pink noise, periodic white noise and periodic pink noise.
This program is also a powerful analyzer of:
Gated frequency 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 sonogram,
Energy decay in reverberant environments,
Room acoustical parameters,
Directivity patterns
Speech intelligibility measures: MTF, STI, RASTI, %AL.
