<div class=indentedbox>
With this enabled, a connecting client will be sent a burst of audio data from the stream. This will have the effect of reducing the startup time for the stream from the perspective of the listener. This is due to the fact that most media players have local buffers that must be filled before the stream begins to play. This may introduce a small latency in the stream (difference in time between when the source plays a clip and the listener hears a clip). If this latency is important to you, then you can disable this feature. The latency is bitrate-dependent, but as an example, for a 128kbps stream, the latency between the source and the player is ~ 1.5 secs WITHOUT burst on connect, and WITH burst on connect the latency is 3 secs.
</div>
<h4>burst-size</h4>
<div class=indentedbox>
The burst size is the amount of data (in bytes) to burst to a client at connection time. Like
burst-on-connect, this is to quickly fill the pre-buffer used by media players. The default
is 64kbytes which is a typical size used by most clients so changing it is not usually required.
This setting applies to all mountpoints.

<h4>authentication</h4>
<div class=indentedbox>
This specifies that the named mount point will require listener authentication. Currently, we only support a file-based authentication scheme (type=htpasswd). Users and encrypted password are placed in this file (separated by a :) and all requests for this mountpoint will require that a user and password be supplied for authentication purposes. These values are passed in via normal HTTP Basic Authentication means (i.e. http://user:password@stream:port/mountpoint.ogg). Users and Passwords are maintained via the web admin interface. A mountpoint configured with an authenticator will display a red key next to the mount point name on the admin screens. You can read more about listener authentication <a href="icecast2_listenerauth.html">here</a>.
