BIFROST is a browser-native audio and DSP workspace for people who want to build a configurable listening environment for focused work, resetting between tasks, or winding down. It generates separate left and right carriers live on the user’s device and makes the signal inspectable instead of hiding it inside a finished audio track. Users can view carrier frequencies, beat frequency, phase, spectrum, signal state, and carrier-to-background S/N while listening. Sessions can be combined with built-in noise, music, and ambience, and FULL ACCESS lets users layer their own music or work audio. BIFROST can run in a modern browser and can also be installed as a PWA; audio processing stays on the device. Every new account receives five days of FULL ACCESS without a card or automatic charge. After that, FREE Mode keeps FOCUS and STUDY available without a time limit. BIFROST does not claim to treat a condition, change brainwaves, or guarantee an outcome.
