Breathalyzer
AI breath removal for audiobooks. Upload a whole book, walk away, and get your clean files back in high resolution — around 99% accurate, seamless, and never robotic. Hours of manual breath editing collapse into one pass.
Get your hours back
Editing finished narration by hand eats up hours — and breaths are one of the most repetitive parts of the job. Noise gates butcher the performance; Breathalyzer knows a breath from a word and clears it cleanly.
Upload. Detect. Done.
No thresholds to dial in, no chapters to scrub through. Drop your files in and let the AI do the pass.
Upload your dialogue
Add your audiobook chapters, VO or podcast files — one at a time or a whole batch.
AI detects every breath
Our model listens through the take and detects each breath — distinguishing it from speech, not just level.
Delivered clean
Breaths are removed seamlessly and your files come back automatically in high resolution — then a quick listen and you're done.
Run a breath pass
Drop a dialogue file to see it in action — start your free trial to process it.
Intelligent, not a gate
Gates and manual cuts either miss breaths or chew up the words around them. Breathalyzer understands what a breath actually is.
~99% accurate — a quick listen is all it takes
Upload your dialogue and Breathalyzer detects and removes the breaths automatically, then delivers your files back in high resolution — no settings, no editing pass. It's around 99% accurate, so we always recommend a quick listen just in case. On the rare breath it leaves, edit or replace that one section by hand — you've still saved nearly all the work.
