TS3 Codec & Bandwidth Calculator
Choose your codec, quality level, and user counts to see exact bandwidth requirements for your TeamSpeak 3 server. All figures include the 1.25× UDP overhead factor.
Configuration
How many users transmit audio at once (typically 2–5).
All connected users (speakers + listeners).
Bitrate per speaker
35.8 kbps
incl. UDP overhead
Per-user download
107.5 kbps
3 simultaneous speakers
Server upstream
2.15 Mbps
to all 20 users
Server downstream
107.5 kbps
from 3 speakers
Reverse: How many speakers can my connection support?
Max speakers (all listening):
279
Uses selected codec & quality. Each listener receives all simultaneous speaker streams.
