# 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 local network.
|
||||
|
||||
It may be used standalone or to extend the [Voicemeeter Remote Python API](https://github.com/onyx-and-iris/voicemeeter-api-python)

For sending audio across a network with VBAN you will need to look elsewhere.

## Tested against
|
||||
|
||||
- Basic 1.0.8.1
|
||||
- Banana 2.0.6.1
|
||||
- Potato 3.0.2.1
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Voicemeeter 1 (Basic), 2 (Banana) or 3 (Potato)
|
||||
- Python 3.9+
|
||||
|
||||
## Installation
|
||||
|
||||
```
|
||||
git clone https://github.com/onyx-and-iris/vban-cmd-python
|
||||
cd vban-cmd-python
|
||||
```
|
||||
|
||||
Just the interface:
|
||||
|
||||
```
|
||||
pip install .
|
||||
```
|
||||
|
||||
With development dependencies:
|
||||
|

```
|
||||
pip install -e .['development']

## Usage

#### Use with a context manager:
|

|
||||
Parameter coverage is not as extensive for the RT Packet Service as with the Remote API.

## Profiles
|
||||
|
||||
Profiles through config files are supported.
|
||||
|
||||
Three example profiles are provided with the package, one for each kind of Voicemeeter.
|
||||
To test one first rename _profiles directory to profiles.

||||
To test one first rename \_profiles directory to profiles.
|
||||
They will be loaded into memory but not applied. To apply one you may do:
|
||||
`vmr.apply_profile('config')`, but remember to save your current settings first.
|
||||
|
||||
profiles directory can be safely deleted if you don't wish to load them each time.
|
||||
|
||||
A config can contain any key that `connect.apply()` would accept. Additionally, `extends` can be provided to inherit from another profile. Two profiles are available by default:
|
||||
|
||||
- `blank`, all strip off and all sliders to `0.0`. mono, solo, mute, eq all disabled.
|
||||
- `base`, all physical strip to `A1`, all virtual strip to `B1`, all sliders to `0.0`.
|
||||

||||
