Measures G, INR, SNR, L_eq, L_Aeq, L_Ceq, BR(L) Magnitude spectrum (linear and -3dB/octave), EDT, T

Conforms to ISO 3382 and IEC 60268-16 standards and supports ISO 3741 and EN 1793-5 standards

Included digital 1/1 and 1/3 octave band filters are fully IEC 1260 compliant

Supports scale model measurements and auralisation

User friendly and fast: from start-up through first measurement in only 3 mouse clicks

High signal to noise ratio, using internally generated MLS signals with optional pink or speech filters

High loudspeaker system output power, using internally generated swept sines with optional pink, speech or bandlimiting filters

Exponentially swept sines for high tolerance against system non-linearities and time-variance. 

Real time averaging of up to 1000 recordings

Portable light-weight measurement set, using notebook PC and blank pistol

Automated measurements reduce the total time required for a measurement session.

Measure impulse response in occupied rooms, using music as sound source.

Supports open loop measurements using a CD or MP3 player to play back an MLS or sweep stimulus.

Level calibration and speech filters for accurate speech intelligibility measurements with the option to add artificial noise spectra.

 Calibration functions allow for the use of standard Windows compatible sound devices and low cost hardware, without the need to manually set input and output levels.

Supports selection from multiple sound devices in a single system

Noise compensated reverberation time calculations

Reverse filtering technique enables accurate short reverberation time measurement, such as in studios and building structures (loss factor)

Waveform editing with unlimited undo 

Uses standard WAV and ASCII files as well as MLSSA TIM files

Export to ODEON or MATLAB.

Calculates and graphically displays statistics over multiple measurements (mean, standard deviation, min-max)

Parameter graphs can be printed, saved as text files or copied to the clipboard for use in reports

Displays waterfall plots and spectrograms

Runs on Windows 2000/XP/Vista
