What Causes Audio Distortion

Audio distortion is the alteration of sound quality, causing artifacts and unwanted frequencies, degrading the listening experience.

Audio distortion can stem from several factors, resulting in undesirable background noises or distortion. Common culprits include clipping, where audio signals exceed recording or playback limits, leading to cut-off peaks and harsh sounds.

Overloading audio equipment beyond its capacity can also introduce distortion. Additionally, background noise like electrical hum or hiss, frequency interference, and acoustic problems like room reflections, echoes, or improper microphone placement may degrade audio quality.

Digital compression, faulty equipment, and signal distortion during conversion can further contribute to the issue. Understanding these causes enables the effective implementation of techniques to clean up audio in Adobe Audition.

How to Clear out Distorted Audio in Adobe Audition

Then how to remove background noise in Adobe Audition? We already know the causes of distorted audio, next, it's time to take targeted measures.

1. Using DeClipper Effect🎙️

The DeClipper effect fixes clipped waveforms by replacing clipped sections with new audio data caused by exceeding the maximum level for the current bit depth. Clipped audio visually appears as flat areas at the top of a waveform, resulting in static-like distortion.

There is also a DeClicker effect that identifies and eliminates clicks and pops originating from various sources, such as wireless microphones, vinyl records, and more. But we'll mainly focus on the former now.

Step 3. Use the DeClipper effect.

Select "Windows" > "Diagnostics" > "DeClipper", and choose the preset from heavy, light, or normal degree. Hit "Settings" to configure other features.

  • Gain Setting: Specify attenuation level before processing; use "Auto" based on average input amplitude.
  • Tolerance: Set amplitude variation for detecting clipped regions; 0% detects perfectly horizontal lines at max amplitude, and 1% is recommended for most clipping.
  • Min. Clip Size: Choose the length of the shortest run to repair; lower values fix more samples; higher values require proximity to other clipped samples.
  • Interpolation: Cubic option uses spline curves for faster processing, FFT option employs Fast Fourier transforms for severe clipping; choose FFT Size for accuracy and processing time.
