Best Way to Fix Audio Distortion in DaVinci Resolve

Direct methods for eliminating clipping, fixing sample rate mismatches, and applying limiters in DaVinci Resolve.

The best way to fix audio distortion in DaVinci Resolve is to normalize clipped peaks, match project sample rates, and apply a hard limiter on the Fairlight master bus.

Here are the direct methods to best fix audio distortion in DaVinci Resolve.

What is the fastest way to eliminate clipping distortion?

If your audio sounds blown out, crackly, or harsh when people speak loudly, the recorded volume has exceeded 0 dBFS and physically clipped the waveform.

To quickly normalize clipped peaks:

  1. Open the Edit or Fairlight page.
  2. Select the distorted audio clip, right-click, and select Normalize Audio Levels.
  3. Set the Target Level to -3 dB or -6 dB.
  4. Click Normalize. DaVinci Resolve instantly drops the loudest peaks below the distortion threshold, clearing up the harshness.

How do you fix sample rate mismatch distortion?

If the audio sounds like it is playing slightly too fast or slow with a robotic "chipmunk" or deep pitch shift, the file's sample rate (e.g., 44.1 kHz) does not match the timeline (e.g., 48 kHz).

To fix sample rate mismatch:

  1. Open the Media Pool and select the distorted audio file.
  2. Right-click and choose Clip Attributes.
  3. Go to the Audio tab.
  4. Change the Sample Rate dropdown to match your master project settings (usually 48000 Hz). Click OK. The audio will instantly resample and play at the correct speed and pitch.

How do you apply a hard limiter on the master bus?

If your individual clips sound fine but the final exported video distorts on YouTube or phones, the combined volume of all tracks (music, effects, dialogue) is pushing the master output over 0 dB.

To apply a hard limiter:

  1. Open the Fairlight page.
  2. Look at the Mixer panel on the right side and find the Main 1 (Master) fader.
  3. Click the small + icon in the Effects slot above the fader.
  4. Go to Fairlight FX > Dynamics > Limiter.
  5. Set the Ceiling to -1.0 dB. This guarantees the final mix will never exceed the maximum digital volume, completely preventing export distortion.
