Audio

Find the channels carrying the mix from the meters, pick them under Record, then press Record at the top. It saves a 24-bit WAV at the input's own sample rate, straight to disk in Chrome and Edge. Nothing is played back, so there's no feedback.

Tempo

BPM over each beat, last minute

Tick interval

Gap before each clock tick, last 10 seconds — the spread is the jitter

Clock and active sensing arrive dozens of times a second, so they are counted above and kept out of the list unless shown. Times are when the browser received each message.
