<p class="MsoNormal">Hi Martin, <o:p></o:p></p>
<div>
<p class="MsoNormal">The ideal burst size is one that fills the receiver buffer as quickly as possible, without being so great as to require the receiver to close their TCP window due to backpressure on the stream from the player.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Most players will begin decoding with ~32-64 KiB of data, and will playback with ~2 seconds of decoded audio. So, if your burst size is set to your bitrate times two seconds, you'll fill that buffer. However, some clients need to do additional
type sniffing and what not before they begin playback. These often have hardcoded buffer sizes that must be filled before playback, and can be as high as 256 KiB (optimized for video, not audio).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">A good tradeoff for a typical quality stream of 192kbit is around 5 seconds, or 120,000 bytes of burst. Most clients will start instantly, will have a plentiful buffer so they won't drop out, but the latency still won't be too high for
most channels.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">Don't forget to check your queue-size as well!<o:p></o:p></p>
