This is intended to be something between the near real time listening interface broadcast on Twitch and the event search interface. The live state of the process that builds events to store in the DB is made available and the browser gets to make its own decisions about what to play


The Settings button lets you configure the parameters about what's considered playable. The back end still has to make its own decision to declare an event starting, so there is limited utility in setting these really low.

- minConvs: How many "conversations" - a grouping of audio clips without much silence between - are in the event

- minAudio: How much audio the event contains, in seconds
- minAudio: How much time span, in seconds, the event covers

If at least one criteria matches, the conversation will be included.

The checkboxes allow you to pick which localities or other groupings will be included. Events matching unchecked groupings will not be included.


The Play/Pause button starts or stops the audio playback. You may need to click this to start playback, as browsers block attempts to play media until you interact with the page.


Below the current audio playback indicator are three buttons that allow you to skip past uninterestings or otherwise unwanted content. You can skip the current...
- Clip: The player will advance to the next clip in the current conversation
- Conv(ersation): The player will advance to the next conversation in the current event
- Event: The player will mark all conversations in the current event as played, effectively advancing to the next available event


In the Event Timeline list, each event has two buttons before the name...
- 🟢/🔇: Toggle mute status for the event. A muted event continues to show in the display but its conversations will not be played
- ⋙: Mark all of the event's conversations as played. New conversations can still be added and played

You can play a specific event by clicking its group name in the Event Timeline.


In the Conversation Timeline list, each talkgroup has a 🟢/🔇 toggle button to mute/unmute a talkgroup's activity within an event. Conversations for muted talkgroups are still displayed but are not played back.


In the Conversations list, you can click a conversation's talkgroup name to play that conversation immediately. This allows quick forward/back movement within the active event.


You can click the audio graph below the playback progress bars to cycle between waveform, spectrum bars, and spectrograph modes.


Most clickable things have hover text and will change cursor. If you find something I missed lmk, it's not like I use a framework or anything. I just bash this crap out.

Historical Events

Historic events will be added to the event queue as Inactive events and will be given priority over events that are still active in the live data feed. Only events that the back end chose to write to the DB will be available.

This doesn't bother to validate whether you've already loaded historical events, so using this function multiple times will likely result in duplicate events in the queue.
