Spectral Repair in iZotope RX 7 is the key to discovering what your waveform won't show you. Use familiar drawing tools to identify and select problem frequencies and unwanted sounds. Salvage unusable material by filling in audio gaps instantly. With a unique visualization and a variety of selection tools at your fingertips, Spectral Repair lets you get closer to your audio—and take a hands-on approach to repairing and enhancing it.
Once a problem sound has been identified, the Spectral Repair algorithms—available in the module or Instant Process Tool—are able to resynthesize the audio while taking into consideration tonal harmonics, nonlinear pitch changes like vibrato, background noise characteristics, and transient events. With the power of these tools, you can remove or attenuate unwanted, interfering sounds—from barking dogs and breath noises to string squeaks, fret noise, and missed/wrong notes. RX 7 Advanced includes a multi-resolution mode that more accurately separates unwanted noise and desired audio.
