# \&activespeakerdelay

To understand the effect of setting \&activespeakerdelay (`activeSpeakerTimeout)` to 2000 in the `activeSpeaker=1` mode, let's analyze the relevant parts of the code:

When `activeSpeaker` is 1 (or 3), the code aims to show only one speaker at a time - the loudest or last-loud speaker. The `activeSpeakerTimeout` affects how quickly the system switches from one active speaker to another. Here's what happens:

1. Without `activeSpeakerTimeout` (or when it's set to 0):
   * The system immediately switches to the new loudest speaker.
   * As soon as a speaker is no longer the loudest, their `defaultSpeaker` status is set to `false` immediately.
2. With `activeSpeakerTimeout` set to 2000 (2 seconds):
   * When a speaker is no longer the loudest, instead of immediately setting their `defaultSpeaker` status to `false`, the system sets a timeout.
   * If the speaker doesn't become the loudest again within 2 seconds, their `defaultSpeaker` status is then set to `false`.

The key difference is in these lines:

```javascript
if (!session.activeSpeakerTimeout) {
    session.rpcs[loudestActive].defaultSpeaker = false;
    changed = true;
} else {
    session.rpcs[loudestActive].defaultSpeaker = setTimeout(
        function (uuid) {
            session.rpcs[uuid].defaultSpeaker = false;
            updateMixer();
        },
        session.activeSpeakerTimeout,
        loudestActive
    );
}
```

This creates a "grace period" of 2 seconds, which has several effects:

1. It prevents rapid switching between speakers if multiple people are speaking with similar volume levels.
2. It allows for brief pauses in speech without immediately switching to another speaker.
3. It creates a smoother transition between speakers, especially in scenarios with multiple active participants.

In essence, setting `activeSpeakerTimeout` to 2000 makes the system more "patient" before switching speakers, which can lead to a more stable and less distracting visual experience for participants in the call, especially in active discussions where speaker dominance might fluctuate rapidly.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vdo.ninja/advanced-settings/mixer-scene-parameters/and-activespeakerdelay.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
