The SpectraPolator - an extension of the Cube Waveform Restorer provides spectrum-based interpolation of the audio material within Steinberg WaveLab.

Typical applications include the removal of coughs or ringing cell phones from live recordings, low-frequency thumps from optical soundtracks, or any specific frequency-domain disturbance. The ability to separately select the "time/frequency" region that requires interpolation, combined with a fast and accurate zoom function and unlimited undo, adds a new dimension to the Cube Waveform-Restorer. The high resolution SpectroGraph displays your audio data in a time-versus-frequency window and then allows you to accurately display, audition, select and interpolate only the required program component.
