Built for Standardized Measurement: The Level Meter offers standard sound level metrics, including time and frequency weighting, defined by ANSI S1.4 and IEC 61672 standards for sound level meters. The Level Meter also supports real-time root-mean-square (RMS) level calculations for non-acoustic signals, including dBV and dBu for audio signals.
Data Logging (Pro Feature): Log sound level data for up to 2 weeks at intervals as small as 0.1 seconds. Use the auto-save feature to keep logging data beyond 2 weeks, for as long as your device has disk space available.
Save Data: Export signal level values and metadata to a data file (.csv, .mat, or .txt). Or, generate a high-resolution image of the display and save it to a PDF file.
Live Web Preview (Pro Feature): Use SignalScope's built-in http web server to monitor signal levels remotely via a standard web browser. Your own custom software can remotely retrieve information from the Level Meter as JSON data to format, analyze, store, or display according to your specific needs.
Input: 1 channel at a time, selected from any available input, output, or virtual output channels
