MOVINdow
Audio-reactive video — video size driven by sound vibration and frequency
MOVINdow can scale a playing video with the vibration and frequency of its audio — the picture pulses with the sound, turning playback into a live sound visualization. On-device, real time, on iPhone, iPad, and Mac. Free.
Sound you can see
Enable the audio-sync option in a video's editing menu and the video's size follows its audio: louder passages push the frame larger, and the response tracks frequency as well as amplitude. No rendering, no plug-ins — it happens live during playback.
Ensembles
Because MOVINdow plays multiple videos in sync, several audio-reactive videos can pulse together — and the effect combines with real-time fragmentation, semi-transparent overlays, and motion trails for layered audiovisual compositions.
Use cases
- Music visuals and VJ-style loops made from ordinary footage.
- Social clips where the beat visibly drives the picture.
- Audiovisual research and education: sound made visible in real time on consumer devices — a simple tool for exploring sound visualization and audiovisual perception.
