Command Line

Flags

• host defaults to "localhost"
• port defaults to 6980
• streamname defaults to "Command1"

Pass host, port and streamname as flags, for example:

vbantxt-cli -h="gamepc.local" -p=6980 -s=Command1 "strip[0].mute=1 strip[1].mono=1"

You may also store them in a config.toml located in home directory / .vbantxt_cli /

A valid config.toml might look like this:

[connection]
Host="gamepc.local"
Port=6980
Streamname="Command1"

Command line flags will override values in a config.toml.

---

Matrix

Sending commands to VB-Audio Matrix is also possible, for example:

vbantxt-cli -s=streamname "Point(ASIO128.IN[2],ASIO128.OUT[1]).dBGain = -8"

A documentation of all available Matrix instructions can be found on the Voicemeeter forum.

---

Script files

The vbantxt-cli utility accepts a single string request or an array of string requests. This means you can pass scripts stored in files.

For example, in Windows with Powershell you could:

vbantxt-cli $(Get-Content .\script.txt)

Or with Bash:

cat script.txt | xargs vbantxt-cli

to load Voicemeeter commands from a file:

strip[0].mute=1;strip[0].mono=0
strip[1].mute=0;strip[1].mono=1
bus[3].eq.On=0

or for Matrix:

Point(ASIO128.IN[1..4],ASIO128.OUT[1]).dBGain = -3
Point(ASIO128.IN[1..4],ASIO128.OUT[2]).dBGain = -3
Point(ASIO128.IN[1..4],ASIO128.OUT[1]).Mute = 1
Point(ASIO128.IN[1..4],ASIO128.OUT[2]).Mute = 1

---

Logging

Pass the -l flag with an argument from 0 up to 6.

0 = Panic, 1 = Fatal, 2 = Error, 3 = Warning, 4 = Info, 5 = Debug, 6 = Trace

For example, to set the log level to Debug:

vbantxt-cli.exe -l=5 "strip[0].mute=0"
