Todd-AO Absentia DX
Automated dialogue cleaning software removing hums, ticks, and background noise.
What it does
Batch cleans raw production sound files through automated hum, tick, and wireless ring removal algorithms. Preserves underlying voice integrity and natural audio harmonics without introducing phase artifacts or degradation. Maintains original WAV file metadata and timecodes to enable direct file swapping in Pro Tools. Generates seamless room tone fills and offers targeted noise reduction for cicadas, birds, and electrical interference.
Why it works
Automated processing eliminates manual spectral editing on hundreds of raw dailies clips simultaneously. Identical metadata outputs allow editors to swap processed audio with originals effortlessly inside DAWs. Non-destructive algorithms target gaps and specific harmonics without altering human vocal frequencies. Includes both desktop drag-and-drop batch tools and native Pro Tools AAX plugins for flexible editing.

Founder story
Todd-AO Absentia DX was developed in 2017 by the team at legendary Hollywood audio post-production facility Todd-AO, led by veteran sound executive Rob Nokes. Built to resolve severe noise issues on a network television show, the algorithm was created to replace hours of repetitive manual audio cleanup. The tool was subsequently released as commercial software to help dialogue editors batch-process production audio efficiently.
