Audio Restoration

Audio Restoration. The process of removing imperfections (such as hiss, impulse noise, crackle, clicks, pops, wow and flutter, background & wind noise, and mains hum) from sound recordings. Using the latest technology, we can perform various automated techniques to remove anomalies to accomplish broadband de-noising, de-clicking and de-crackling, as well as removing buzzes and hums. We will manually remove “pops and ticks” from recordings, and use the latest spectrographic ‘retouching’ techniques to suppress or remove discrete unwanted sounds. With a DAW (digital audio workstation), even the smallest anomalies can be removed, and often without leaving any artefacts behind. While fully automated audio restoration solutions exist, it can still be a time-consuming procedure requiring skilled audio engineers with specific experience in music and film recording.

Common problems we can fix include:

  • Ambient background noise (incl. echo/reverb);
  • Tape hiss;
  • Electronic interference such as hum and buzz;
  • Sudden background noises (coughs, ringing cell phones, etc.);
  • Clicks and pops from older vinyl, shellac, or phonograph recordings;
  • Distorted audio where possible;
  • Sibilance and plosives;
  • Clipping in both the analogue and digital domain;
  • Unwanted breaths in narrated audio clips;
  • Mouth-produced clicks, pops and smacks;
  • Mic bumps and rustling (especially on Lavaliere microphone recordings).

Examples of audio material that we can restore include:

  • Camera or mobile phone recordings;
  • Podcast material;
  • Professional voice-overs (narrations, audiobooks);
  • Seminar recordings;
  • Conference audio (e.g. Google Meet or Zoom);
  • Audio from YouTube or general marketing videos;
  • Old video tapes, cassettes or vinyls.

In the following video, supervising sound editor, and re-recording mixer Daniel Saxlid uses RX to repair and restore Orson Welles’ long-lost final film, “The Other Side of the Wind”. With pieces of the film scattered across the globe and evidence of multiple transfers, Saxlid had his work cut out for him. Watch how he uses the powerful tools in RX to bring this previously unseen gem to your ears.

Details About Our Service

  • Please don’t order before sending us a sample or part of your audio that needs to be fixed;
  • We will provide a sample for free, so you will know what you will get;
  • Up to 3 free revisions are free of charge;
  • We charge $20/minute for up to 5 minutes. But we also do custom quotes for longer material. Please send us a message to discuss your project;
  • The higher-quality files you send, the better the result. Our default format is 16-bit/24-bit, 44.1/48kHz (WAV or AIFF format preferred). If MP3 is all you have, we’ll do our best to restore the material (prior to examining the files). If we can’t fix the given audio, we won’t accept the assignment.

Finally, check out this Izotope article on removing background noise from dialogue recordings. It should provide some additional insight into the work that we perform.
