描述
PROFESSIONAL-GRADE ANALYSIS
Built with ANSI S1.11 and IEC 61260 Class 1 compliant filters, RTA provides measurement accuracy that meets international standards. Choose between full octave and 1/3 octave band analysis modes to match your specific measurement requirements.
REAL-TIME SPECTRUM VISUALIZATION
Watch audio frequencies come alive with smooth, responsive spectrum displays. Switch between classic bar graphs and continuous line plots. Enable peak hold and minimum tracking to capture transient events and identify the quietest moments in your measurements.
COMPREHENSIVE NOISE CURVE OVERLAYS
Compare your measurements against industry-standard noise criteria including NC (Noise Criteria), NCB (Balanced Noise Criteria), PNC (Preferred Noise Criteria), RC (Room Criteria), NR (Noise Rating), and X-Curve for cinema calibration. Essential for HVAC noise assessment, room acoustics evaluation, and venue certification.
FLEXIBLE DECAY AND AVERAGING
Select from multiple decay time constants including Fast (35ms), Medium (125ms), Slow (500ms), and Very Slow (1s) to match measurement standards or personal preference. Choose between real-time display, peak hold, and running average modes.
DEVICE CALIBRATION
Built-in calibration profiles for popular iOS devices ensure accurate measurements right out of the box. Import custom calibration files for external measurement microphones to achieve laboratory-grade precision.
SAVE AND EXPORT MEASUREMENTS
Capture snapshots of your measurements and custom notes. Export your data in multiple formats including CSV for spreadsheet analysis, JSON for software integration, and PDF for professional reports.
