[QUOTE="Morfeas, post: 160013, member: 68"] [I]The ARTA software consists of following programs: [/I] [INDENT][I][B]ARTA [/B]- program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements. [B]STEPS[/B] - program for frequency response measurements with stepped-sine excitation. [B]LIMP[/B] - program for the loudspeaker impedance measurement and loudspeaker parameters estimation. [/I][/INDENT][I]The ARTA program has functions of following measurement systems: [/I] [INDENT][I][B]Impulse response measurement system[/B] with signal generators: periodic white noise, periodic pink noise, MLS, linear and logarithmic swept-sine. [B]Dual channel Fourier analyzer[/B] with signal generators: white noise, pink noise, periodic white noise and periodic pink noise. [B]Single channel Fourier analyzer[/B] with signal generators: periodic white noise and periodic pink noise. [B]Spectrum, octave band and THD analyzer[/B] with signal generators: sine, two sine, multitone, white noise, pink noise, periodic white noise and periodic pink noise.[/I][/INDENT][I]The ARTA program is also a powerful analyzer of: [/I] [INDENT][I]Gated frequency response, Smoothed frequency response (in 1/n-octave bands), Step response, Impulse response envelope (ETC – curve), Cumulative spectral decay curve and sonogram, Energy decay in reverberant environments, Room acoustical parameters, Directivity patterns, Speech intelligibility measures: MTF, STI, RASTI, %AL. [/I] [/INDENT][I]The STEPS program enables the measurement of the frequency response with a high dynamic range and a high noise immunity. Simultaneously with a frequency response measurement the STEPS estimates levels of 2nd, 3rd, 4th, 5th and higher order harmonic distortions. [/I] [I]The LIMP program is specialized for the loudspeaker impedance measurement and for the estimation of physical and Thiele-Small loudspeaker parameters.[/I] [URL]http://www.fesb.hr/~mateljan/arta/index.htm[/URL] Αξίζει και μια ματιά στο [URL]http://www.fesb.hr/~mateljan/arta/support.htm[/URL] Enjoy [/QUOTE]
