TempoSync — Frame-accurate audio playback and timecode for set and post. Built for filmmakers, sound recordists, DITs, playback operators and musicians, TempoSync turns your iPhone, iPad or Mac into a reliable playback and timecode machine. Load a clip, lock it to timecode, and play it back perfectly in sync — on one device or across many. MATCH YOUR CAMERA'S SENSOR FRAME RATE Shooting off-speed for slow motion or fast motion? Set your project's base frame rate and your camera's sensor frame rate, and TempoSync automatically adjusts playback speed so your audio stays perfectly in sync with the picture. Best of all, the pitch is preserved — your music and dialogue never sound sped up or "chipmunked". ROCK-SOLID TIMECODE & LTC - Frame-accurate SMPTE timecode display - Generate LTC (linear timecode) as an audio signal to feed cameras and recorders - Set a custom start timecode or use the file's original timecode - Fullscreen timecode view for the whole crew to read at a glance METRONOME & PRE-ROLL - Adjustable BPM, time signature, tap tempo and offset - Configurable click sounds and beat pattern - Pre-roll count-in before the clip starts DIGITAL SLATE & LOGGING - On-screen Scene / Shot / Take slate with auto-increment - Automatic take logging: date, time, start TC, end TC, scene, shot, take and clip name - Rehearsal mode to run takes without logging - Review, edit or delete entries and export the log as CSV or PDF MARKERS, IN/OUT & WAVEFORM - Set, name and jump between markers on the timeline - In/out points for precise playback ranges - Metal-accelerated waveform with smooth scrubbing - Multi-track mixer with per-channel volume and mute (embedded WAV channel names are used automatically) SEND TIMECODE - Stream timecode over Art-Net and OSC to your lighting and media systems WAV EXPORT - Export a Broadcast Wave (BWF) file with embedded timecode metadata - Optionally bake in the metronome and LTC tracks and pre-roll - Speed changes keep the original pitch MULTI-DEVICE SYNC - Connect a host and multiple clients over the local network - Timecode and slate information are shared live, so every screen shows the same take WORKS EVERYWHERE - iPhone, iPad (portrait and landscape) and macOS - Available in English, German, French and Spanish FREE & PRO Use TempoSync for free to load a clip, play it back, use the mixer and set the sensor frame rate up to 50 fps.
