 # VBAN CMD
-This package offers a Python interface for [Voicemeeter VBAN TEXT](https://vb-audio.com/Voicemeeter/VBANProtocol_Specifications.pdf#page=19) as well as the [Voicemeeter RT Packet Service](https://vb-audio.com/Voicemeeter/VBANProtocol_Specifications.pdf#page=27) which allows a client to send and receive parameter values over a network.

-For sending a text command several configuration options are available:
-- `ip`: remote address
-- `streamname`: default 'Command1'
-- `port`: default 6990
-- `channel`: from 0 to 255
-- `bps`: bitrate of stream, default 0 should be safe for most cases.

 It is advised to use this code with a context manager.
