Step by step

  1. Open the track’s repair workspace

    Choose Perform Surgery on the track. The waveform, spectrogram, meters, and grouped effect controls open together.

  2. Select a region and listen

    Drag across the waveform to set In and Out. Surgery enables a loop of that region. Use the small Play button at the top to audition it.

  3. Try a treatment

    Enable an effect and open its controls. This example uses High Pass at 80 Hz. Toggle the effect off and on while listening so you can compare it with the original.

  4. Keep the useful treatment

    Choose Commit to Region, then Apply. Apply renders the committed treatment into a new aligned track. Exit Surgery to return to the editor.
