Talk ratio analyzer
Tap to start
Best used to practise a pitch or an answer: record only yourself, and the result tells you how much of the time you were talking.
Detection sensitivity
Raise it for a quiet recording, lower it for a noisy room.
The audio never leaves this tab, and you can check
Recording is reduced to loudness numbers as it arrives and the samples are discarded; a file you pick is read off your disk and decoded locally. There is no upload, no transcription, no account, and no server involved at any point.
Rather than trust that: open developer tools, watch the Network tab, and run an analysis. Nothing carrying audio goes out. The measurement code has no network access in it — that is what makes this free to run at any volume and impossible to abuse.
The honest limit: this is the simple version. Craqly's desktop app does real dual-channel separation — your microphone on one channel, the call on the other — which is how it reports a genuine two-sided talk ratio live during a call. A browser tab handed one mixed recording cannot do that, and a tool that claims otherwise is guessing.
