ARTA - program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements. You can read ARTA as Audio Real Time Analysis, and also as Art for Audio

[b]The ARTA program has functions of following measurement systems:[/b]

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, periodic square and triangle, white noise, pink noise, periodic white noise and periodic pink noise.
Triggered storage scope with spectrum and short-time Fourier analysis.
Two-channel voltage level meter and third octave analyzer

[b]With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes:[/b]

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.

[b]The ARTA program is also a powerful analyzer of[/b]:

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
