Every camera and recorder captures the same sound. CamHeard reads that audio and aligns every clip to it — frame-accurate, fully offline, no timecode and no markers required.
A sync tool earns its place when you can trust its output without double-checking. CamHeard is engineered around that principle — and validated on real productions, not demos.
CamHeard syncs using the audio your devices already recorded. No timecode hardware, no slate, no on-set preparation — existing footage syncs as is.
Batch every angle in one pass. The match is sample-accurate, so the result is the same whether it's a 2-minute take or a 4-hour conference.
All processing happens locally and offline. No uploads, no cloud queue, no account — a safe choice for embargoed and NDA-protected productions.
Export a multicam-ready timeline in the format your editor expects. Open and cut — the alignment travels with the sequence.
Built on our latest audio-analysis technology: the same footage always produces the same result, with sub-frame accuracy verified against reference edits.
All computation runs on your own computer, offline. Nothing is uploaded and no account is required.
Every placement is backed by audio evidence; anything without a reliable match is clearly flagged for review — your timeline is never quietly wrong.
The tool a generation of editors relied on is no longer sold or updated. CamHeard is the same job — sync by sound — done by a state-of-the-art engine that's actively developed.

Yes. CamHeard is a multicam audio-sync app for macOS and Windows, in the same category. It aligns every camera to your recorder by sound, is deterministic and frame-accurate, works fully offline, and is a one-time purchase with no subscription.
Yes — a multi-cam shoot is exactly what it was built for. Drop in every camera and your recorder, and CamHeard lines up all the multicam clips by sound. Two cameras or twenty, one room or several, with or without shared timecode.
When timecode is there, the sync leans on it and comes out most accurate. When it is not, CamHeard syncs by sound — which is what it was built for, including reverberant venues and different microphones.
Adobe Premiere Pro and DaVinci Resolve (FCP7 XML), Final Cut Pro (FCPXML). CamHeard writes a separate file for each editor, so the tracks land the way that editor expects.
Every download starts with a 14-day trial of the full app; after that the free version syncs up to 20 clips per project, forever. A one-time licence is $129 (Pro, 1 machine) or $239 (Studio, 3 seats). No subscription.
No. Everything runs locally on your own computer; your footage and audio never leave it. Your files are not changed either — CamHeard only listens to them and syncs them.
macOS 11 (Big Sur) or later on Apple Silicon (M1 or later), or Windows 10 (64-bit) or later.
The more footage, the longer. Your computer and your storage affect it most: footage on an SSD (internal or external) syncs several times faster than on a spinning hard drive. For a large multi-hour shoot, copy the footage to an SSD first.
Because there was nothing to sync it with. Most often that is files without sound, b-roll, cutaways and pickups — material shot on its own. It is normal and does not mean something broke. There is a walkthrough in the step-by-step guide.
The material will be placed by when it was shot, so you are not left hunting for it. But if there is one camera and the sound is recorded on it, there is nothing to sync against — such a project is simpler to drop straight into your editor.
