RT-Capture 2

RT-Capture is a Real Time Analyzer (RTA) combined with an SPL-meter (Sound Pressure Level). RT-Capture uses a standard PC-soundcard and supports measurement from two microphones. RT-capture records a log-file with SPL-data (such as Leq, Lamax, Lamin) and do compressed sound recording for self-governance of sound levels. The log-file can be watched graphically and audio can be played back from a cursor point in the graph. The SPL-measurement is validated to the IEC 61672 standard and other international standards. Protocol according to several national standards can be printed. The log-file can be scheduled to be emailed during logging.

KEY Features

RT-Capture uses a stereo soundcard and supports 2-channel measurements
Built-in microphone calibration and frequency compensation
All settings can be password-protected and can be saved to a User-preferences file

SPL metering according to IEC 61672 standard.
Built-in weighting filters: A, C, AU and Z (flat)
Selectable time response; Slow (1s) / Fast (0.125s)

Instantaneous SPL Metering (RMS and Peak)
Six different Equivalent Continuous SPL, Leq, are calculated simultaneously; Continuous, Current, Short time (User time), Remaining, Period and Running Leq
All SPL data is event-logged and can be recorded to a log-file along with additional information
Records compressed audio-file for verification

Logging can be started by a scheduler.
Automatic filename generation.
SPL log-file can be printed in selected time period.
SPL log-file can be exported as tab-separated text format.
SPL log-file can be emailed periodically.

RTA Features

Dual-channel real time spectrum analyzer and running Sonogram simultaneously in the same window.
1/1 to 1/24 octave resolution RTA
Real time spectrum analysis display of both inputs (individually, overlaid or RMS-sum)
A novel Dynamic Difference RTA shows the power transfer function between the channels.

Staircase or Bar Graph display modes
Selectable IEC or Scientific frequency scales
-100 to 200 dB magnitude scaling
Built-in, synchronised noise generator

SPL Display Features

User definable selection of display quantities.
One dedicated Leq value has user selectable time period (10s – 1h)
“User Leq” is useful to verify sound level adjustments.

“Remaining Leq” gives a guide how much is left to reach a target Leq after the performance period.

Peak quantities like LCpeak, LCpeak-hold, LAFmax , LAFMax-hold can be displayed simultaneously.
Continuous and periodic Peak counter; counts if the peak quantities are above the limit.

Requirements

PC with Windows 2000 SP4 or XP or Vista
Soundcard with 2 inputs and 2 outputs, full duplex
Omni directional measurement microphone and pre-amp
