- program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements. 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.
With calibrated microphone, ARTA can be used as a virtual IECC class 1 SPL meter with 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),
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,
Speech intelligibility measures: MTF, STI, RASTI, %AL.
Following bugs are removed: - Arta 'Load target' command - accept files with arbitrary number of points (removed hidden restriction on 720 points)
- Arta peak meter in SPL windows is tracking the peak in every recorded blocks
- Limp correctly reports Le.
- Steps correctly reports X-axis values in Distortion vs. excitation plot.
