About FreqPrism
FreqPrism is a brand of Web apps built around one idea: turn sound into visuals. Just as a prism splits light into a spectrum, our tools pull the frequency and spatial information hidden inside sound out into something you can see.
Oto-e
Oto-e generates a music visualizer video (MP4) that reacts to your audio in real time, from a track and a background image. Built for uploading BGM to YouTube — everything from import to export happens in your browser.
Stemscape
Stemscape plays back multiple stem tracks in sync and visualizes, in real time, where each part sits in the stereo field and which frequency band it occupies. Useful for checking the balance and space in a mix, and just as fun to watch on its own.

Our approach to privacy
Both apps process everything you load — audio and images — entirely in your browser. Nothing is ever uploaded to a server. See our Privacy Policy for details.
