New processing and analysis tools accept browser-decodable audio up to 20 MB and 60 seconds per file, with at most two channels. Longer files can be cut into shorter clips. Processed audio exports as 16-bit PCM WAV.
Does my recording leave my device?
The available upload-processing tools decode and process audio in this browser. Microphone tools ask for permission. System text-to-speech may use an online voice provider when an online voice is selected. Available AI tools download models after you start, then process audio locally. Planned tools do not accept files.
What should I know about the results?
Exports 16-bit PCM WAV. Start must precede end.
Try a short clip first and listen before sharing. Processing can introduce artifacts. Analysis describes the recording, not the identity, health or trustworthiness of a person.
