Feeds your reversed audio directly into Whisper — the backward clip is the input, nothing is re-reversed. Whisper is OpenAI's open-source speech recognition AI, running entirely in your browser via WebAssembly — no audio ever leaves your device. It reports any words or phonemes it hears in the backward speech, surfacing hidden sounds your ear might miss.
