When tuning an audio system, it’s important to use the right audio signal to get the best possible sound quality. The best audio signal for tuning a system is a sine wave. A sine wave is a pure, single-frequency tone that can be used to test the frequency response of a system.
Sine waves are used for tuning because they are easy to generate and they can be used to test a wide range of frequencies. Sine waves can also be used to test the phase response of a system, which is important for ensuring that all of the speakers in a system are working together properly.
