Rational Acoustics continues its consistent support and development of the Smaart test, measurement and system optimization platform with the recent release of version 7.4 (v.7.4). Released in fall 2012, the Smaart v.7.4 update features an enhanced and re-designed IR mode that includes the full functionality of Smaart’s renowned “AcousticTools Intelligibility Module”. This FREE update for all registered v.7 users provides a robust and intuitive set of tools for making and analyzing Impulse Response measurements
Smaart v.7 is inherently multi-channels and multi-platform, able to access modern multi-channel input devices and operate native in both Windows and Mac operating systems (including 32- and 64-bit versions). A new object-oriented program architecture allows users to run as many simultaneous single-channel or dual-channel measurement engines as their PC will allow. Enhanced, strengthened and awesome-ized measurement engines provide quantum leaps in measurement power, stability, accuracy and ability. A simpler, friendlier graphic user interface reduces UI clutter and provdes modern “point n’ grab ‘n click” mouse-based controls.
NEW IN v.7.4: Impulse Response Overhaul including: Adjustable Time 0 (T0), Impulse Measurement Crop, IR Spectrograph Controls On Plot, Wave Recorder, Triggered Swept-Sine, Speech Weighted Noise, Reverse Time Integration Curve (Schroeder Integration). All-Bands Table including Reverberation Time (T60/RT60), Early Decay Time (EDT), Direct to Reverberant Ratio (D/R), Early to Energy Ratios (Clarity factors) for 35, 50 and 80 ms (C35, C50 and C80), Articulation Loss of Consonants (ALCons), TLow (average reverberation time for the 125 and 250 Hz octave bands), THigh (average reverberation time for the 500 and 1000 Hz octave bands), Bass Ratio (TLow / THigh ), Speech Transmission Index (STI measured indirectly from impulse response), STIPA (an abbreviated form of STI for Public Address systems), Common Intelligibility Scale (CIS) ratings for intelligibility measurements, User Defined Zooms and Views, Dual Spectrographs, Peak Holds, Locked Cursors, Multi-Device Transfer Function Measurements
