Audio Measurement and Analysis Software

 Home

 

Welcome to the home page of ARTA software - 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 program 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 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.
