Transcribe with local Whisper
Long MP3 recordings are decoded into short sections using local FFmpeg. A multilingual Whisper model is downloaded on first use. On phones, the more compatible CPU engine is selected automatically; on desktops, WebGPU can be faster. Your audio stays on this device. Keep this tab open.
For noisy Dutch, select Dutch and try Base. Cleanup is mild and optional: it cannot remove overlapping voices or recover inaudible speech. Base downloads more model data directly from Hugging Face.
Detailed processing status and errors
Every percentage refers to an individual model file. The engine is only ready when it says Whisper initialized. A stalled engine is stopped and retried on CPU when possible.
Choose a recording to see diagnostic steps.
Partial transcripts remain downloadable after each section, even if the model fails later. Stop or resume in this tab. Do not close or reload before exporting.
Recording and transcript stay on this device. FFmpeg and the ONNX runtime are served by GratisTools; Whisper Tiny/Base model weights come from Hugging Face. CPU works without WebGPU but can be slow, especially with Base. Check transcript and timestamps.
