![]() ![]() So, the system compresses the peaks that have passed the TOD, lowering the wave’s once-curved arcs to straight lines along those dotted lines. Once the peaks cross the dotted lines, the system is unable to recreate this part of the signal. ![]() Note that this concept will apply to all signals, not just sine waves.Īs the wave’s amplitude increases, its peaks approach the dotted lines, which represent the threshold of distortion. On the left, you see the first cycle of an undistorted sound wave (a sine wave, the simplest waveform), resonating in positive and negative cycles (going above and below 0 amplitude). The vertical axis is the amplitude of the signal (which we perceive as the volume or loudness). This concept is applicable in both an analog and digital setting. This can be done gently or harshly, depending on the system and settings at play.Ībove is a diagram showing theoretically how distortion works. Because the system can’t accurately capture or play this back, it compresses the parts of the signal that cross the threshold of distortion down to this level. For the sake of this article, we’ll refer to that level as the “threshold of distortion”, or TOD. ![]() In most DAWs like Ableton, Logic, and Pro Tools this level is 0dB. A system, analog or digital, is built to expect signal below a certain level. In an analog setting, this limit is determined by the circuitry of equipment used, and in a digital setting it’s determined by software.Įssentially, there is a ceiling for how loud an audio signal can go. In an audio setting, this usually occurs when the signal is set to go louder than it’s able to do. Distortion is a disturbance in a signal’s waveform, which can be caused by several processes. 4.2 How to use Distortion to Improve Your Soundīefore discussing how to get rid of distortion or when it can help, it’s important to understand what it is in the first place.3.3 Distortion from Compressors/Limiters.3.2 Distortion at the Master Fader (and solutions).3.1 Distortion at the Channel Fader (and how to solve it).3 Distortion within the Processing Chain (and how to solve it).2.1 Distortion in the Recording/Audio Signal (and how to solve it). ![]()
