audio streaming

Test and inspect HTML <audio> element behavior with full telemetry — buffering, events, readyState, and playback state — all in the browser.

Settings

rebuild vs live

Settings are tagged rebuild or live:

  • rebuild — changing these requires clicking "Load / Reload" or "Rebuild" to take effect. They are applied when the <audio> element is created. Includes: src, preload, crossorigin, autoplay.
  • live — applied immediately to the existing <audio> element without a rebuild. Includes: loop, muted, controls, disableRemotePlayback, playbackRate, volume, controlsList.

Range bars

Three bars visualize the browser's time ranges for the current audio:

  • buffered — portions of the media that have been downloaded
  • seekable — portions the browser will allow seeking to
  • played — portions that have already been played

The vertical line shows currentTime.

Event log

All standard HTMLMediaElement events are captured. Use quiet mode to suppress noisy timeupdate and progress events (throttled to one every 500 ms). Toggle autoscroll to follow new events automatically.
