Unlocking the potential of Sound-to-Text

Transcribe converts dialogue recordings into text. Whether it's production sound, ADR, loop group sessions, voice-overs, or any voice recording. Search for alternative lines or specific words and expressions in a user-friendly spreadsheet or directly within your sound database app.

ALTS finder

Seamlessly navigate through your transcribed dialogue, listen and compare different takes, and spot the selected takes directly into Pro Tools.
This efficient workflow grants editors more freedom to focus on the creative aspects of their work.

Search, Playback, and Spot ALT takes without using an external application.

Fix Sync

AFS automatically corrects the offset between AAF clips and their corresponding expanded channels in Pro Tools. It nudges the clips, so no new media is generated.

The De-Hum feature is a lifesaver!
One click and it’s gone. When you have complicated harmonic hums… even more amazing!!!
Then the Doppler Remover has done miracles to save an unusable track.
Keep up the good work and I look forward to further improvements as you develop them!!!

Supervising Sound Editor

I used the Transcribe feature for the first time on a feature. It's an absolute godsend for finding Alts. You can either use an xls database to search for keywords by character, or have cue metadata added to your sound roll WAVs,
and search for text within your sound database app, and spot to
Pro Tools more easily. Genius! 
I'll be using it on every project.

Absentia DX saves the day again!
I had a scene in Ozark that I wanted to throw at Absentia DX just to see what it could do with very high-frequency insects (cicadas and other insects from Atlanta). I used Hum Remover Strong and had Broadband Remover checked as well. It reduced the problem significantly and it was a huge improvement.

Hum Remover

Hum Remover Smooth is safe for all dialog.
Our intelligent algorithm removes obvious hum and harmonics and leaves the dialog untouched. 

Batch process all dailies before editing.

The Smooth and Strong presets are specially built to leave the dialogue untouched while taking care of the residual noise.

Hum Remover Presets

​Smooth removal of hums and wireless rings. Can be safely used on batch processing.

​Strong removal of hums and wireless rings. Can be safely used on batch processing.

Tighter (closer to dialogue) removal of hums and wireless rings.

Removal of hum from camera, generators, and projectors.

Removal of hum produced by Electro-Magnetic Field interference, such as Radio or Transmitters.  

Smooth removal of hums and wireless rings, focused on the low end that overlaps dialog fundamentals.

Sonogram Player

The Sonogram window allows to view the Spectrum of a poly-wave file and play it channel by channel. Drop a WAV file onto the Sonogram box to see its spectrum. Open the History window and compare Original vs Processed in the Spectrogram.

More Tools
