"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!!!"

"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."
