What this audio tool does

Play an episode, mark chapter times, and download a clean timestamp list. Everything stays on this device while the page is open.

The page uses browser-native audio APIs and derives every displayed result from the current input or interaction.

Browser codec and microphone support varies. Unsupported operations stop with a specific message instead of creating a mislabeled file.

Supported formats and limits

Files must be decodable by the current browser. WAV is used for sample-accurate edited output; reports use plain text or CSV.
