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".
