Post Description

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 and interfaces for audio signal acquisition and generation.
The ARTA software 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. Simultaneously with a frequency response measurement the STEPS estimates levels of 2nd, 3rd, 4th, 5th and higher order harmonic distortions LIMP - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.

The ARTA program has functions of following measurement systems

    Signal generator of following signals: white noise, pink noise, periodic white noise, periodic pink noise, speech signal, sine, two sine, multitone, triangle, square.
    Impulse response measurement system
    Single and Dual channel Fourier analyzer
    Spectrum, octave band and THD analyzer
    Triggered storage scope
    Two-channel voltage level meter and third octave analyzer

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 specific loudness, loudness in sones and loudness level in phones.

The ARTA program is also a powerful analyzer

    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.
