DIGITAL AND ANALOG SIGNAL ANALYSIS

Precise audio analysis for analog and digital signals

Alongside the base unit, the “Toolmonitor AudioAnalyzer” is at the heart of audio analysis. It combines control, signal acquisition, measured-value display, signal visualization, and evaluation in one application, and integrates directly into the test environment through the TestSuite software platform.

Functions such as an oscilloscope, FFT spectrum, frequency and phase response, measurement-curve analysis, filtering, and live display enable fast, repeatable evaluation of acoustic events and electrical audio signals.
