Built for Standardized Measurement: The Max Levels tool employs real-time Order 3 digital Butterworth bandpass filters, in whole octave frequency bands, designed with standard filter characteristics defined by ANSI S1.11 and IEC 61260. And, it applies standard sound level metrics, including time and frequency weighting, defined by ANSI S1.4 and IEC 61672 standards for sound level meters.
Traffic Light Display: Easily see whether your custom sound level limits have been exceeded or are close to it. Green, yellow, and red indicators show the current signal level as well as its maximum value since the start of the current measurement, simultaneously, for 2 sets of thresholds defined in individual octave frequency bands.
Save Data: Export spectrum magnitude values and metadata to a data file (.csv, .mat, or .txt). Or, generate a high-resolution image of the graph and save it to a PDF file.
Input: 1 channel at a time, selected from any available input, output, or virtual output channels
