PROFESSIONAL METERING SYSTEMS
Choose from 7 different metering standards used by audio professionals worldwide:
Decibels (dB SPL) - Measure environmental sound pressure levels from whisper quiet to rock concert loud
LUFS - Broadcast-standard loudness measurement with both momentary and short-term readings, following ITU-R BS.1770 specification
Peak Level - Track instantaneous signal peaks in dBFS with clipping detection
RMS Level - Monitor average power levels with 300ms integration time
VU Meter - Classic analog-style metering with authentic ballistics, configurable reference levels (Classic, EBU, Digital)
Crest Factor - Analyze dynamic range by measuring the ratio between peak and RMS levels
Signal-to-Noise Ratio - Evaluate signal quality against background noise with intelligent noise floor tracking
