WaveWindow AU is a software oscilloscope designed to visualize audio signals with precision and clarity. It offers multiple display modes, including dots, lines, and Lissajous figures, allowing users to analyze waveforms in different graphical styles. The interface supports several synchronization methods such as asynchronous, synchronous, and capture modes, providing flexibility in how the audio data is presented.

Users can adjust the horizontal and vertical scales to zoom in or out on the waveform, with horizontal scaling ranging from 1x to 4x and vertical scaling from 1x to 10x. The oscilloscope includes focus settings—fine, medium, and large—that enhance the detail and clarity of the visualization. A grid overlay can be toggled on or off to assist in waveform measurement, while color preferences allow customization of the display to suit different viewing environments.

WaveWindow AU also features a pause button for freezing the waveform display, enabling detailed inspection of specific signal points. This software oscilloscope is a valuable tool for audio engineers and producers who need to monitor and analyze audio signals in real time, helping to ensure that sound quality and signal integrity meet professional standards.
