vban-cli 0.5.0

A command-line interface for Voicemeeter leveraging VBAN.

vban-cli

---

This CLI is still in an early stage of development with many more things that could be implemented. However, the commands that are implemented should be working without issues.

Install

With uv

uv tool install vban-cli

With pipx

pipx install vban-cli

The CLI should now be discoverable as vban-cli

Use

Strip Command

see vban-cli strip eq --help for more info.

Strip EQ Cell Command

Usage: vban-cli strip <index> eq cell <band> COMMAND [ARGS]

vban-cli strip 0 eq cell 0 on false

see vban-cli strip eq cell --help for more info.

Bus Command

Usage: vban-cli bus <index> COMMAND [ARGS]

examples:

vban-cli bus 0 mode tvmix

vban-cli bus 1 mute true

see vban-cli bus --help for more info.

Sendtext Command

Usage: vban-cli sendtext TEXT

To Voicemeeter

examples:

vban-cli sendtext 'Strip[0].Mute=1;Bus[0].Mono=2'

To Matrix

vban-cli sendtext 'Command.Version = ?'

vban-cli sendtext 'Point(ASIO128.IN[1..4],ASIO128.OUT[1]).dBGain = -3.0'

Implementation Notes

1. The VBAN TEXT subprotocol defines two packet structures ident:0 and ident:1. Neither of them contain the data for Bus EQ parameters.
2. Packet structure with ident:1 is emitted by the VBAN server only on pdirty events. This means we do not receive the initial state of those parameters on initial subscription. Therefore any commands which are intended to fetch the value of parameters defined in packet ident:1 will not work in this CLI.
3. Packet structure with ident:1 defines parameteric EQ data only for the first channel.

Further Notes

I've made the effort to set up the basic skeletal structure of the CLI as well as demonstrate how to combine subcommand groups with subcommand groups so more can be implemented, it just needs doing. There may be restrictions on some things however, for example, retrieving values is only possible for parameters defined in the protocol. Setting parameters can be done for anything possible by a string request.

Shell completion scripts are available (for zsh, bash and fish) but they haven't been thoroughly tested.

If there's something missing that you would like to see added the best bet is to submit a PR. You may raise an issue and if it's quick and simple to do I may (or may not) do it.
