Clip Fix

Clip Fix attempts to reconstruct clipped regions by interpolating the lost signal. It is only likely to be effective for repairing lightly clipped audio.

Note carefully that when you apply an effect to a time-stretched clip the changed speed of the clip will be automatically rendered. If you apply an effect to a selection within a time-stretched clip then Audacity will split the original clip so that the selection can be rendered as part of applying the effect.

If you apply this effect with an envelope present then there is a bug whereby the envelope is removed and the audio reverts to its full amplitude state prior to the effect being applied.

Threshold of Clipping (%)

How close to the maximum sample magnitude any sample must be to be considered clipped.

• If processing is slow, select only a few seconds of clipped audio at a time.
• This effect assumes that the audio is clipped at the same dB level for both positive and negative peaks. If either the top or bottom of the waveform is successfully reconstructed but not both, try applying DC offset correction before applying Clip Fix.

Reduce amplitude to allow for restored peaks (dB)

Reduces the amplification of the current selection (default is -9 dB) to provide headroom for the clip-fixed reconstruction.
