Automatic video & audio sync by sound — from a single camera with a recorder to a full multicam shoot, correct the first time.
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 Mac, 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 macOS multicam audio-sync app 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.
No. CamHeard syncs by the audio itself, so it works even when cameras and recorders share no timecode — including reverberant venues and different microphones.
Adobe Premiere Pro (FCP7 XML), DaVinci Resolve and Final Cut Pro (FCPXML). The FCPXML auto-links media on import when your footage carries timecode.
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 Mac; your footage and audio never leave your computer.
macOS 11 (Big Sur) or later on Apple Silicon (M1 or later).
Typically seconds to a few minutes, depending on the amount of footage. CamHeard reads the audio track of every clip, so storage speed is the main factor: footage on an SSD (internal or external) syncs several times faster than on a spinning hard drive. For large multi-hour shoots, copy the footage to an SSD first.
