Quick Audio Sonar is designed to help you tune your professional audio system. It gives information about frequency, phase and can correlate two different audio signals to measure audio delay. For a quick start, you can press the apply button. Then, you whistle and watch the graph detecting your whistle tone. If nothing is detected, you select another input or output device by pressing the DSP RX and DSP TX buttons respectively. Then, you press apply again. By pressing AudioConfig, a new window will pop up which allows selecting which input and output channels are correlated. By default, the input channel left (INPUT-0) is correlated by itself. To measure delay, you need to select main input channel OUTPUT-0. Then, you select White Noise for output channel 0.
