# Python Wrapper for Voicemeeter API
|
|
|
|
This package offers a Python interface for the Voicemeeter Remote C API.
|
|
|
|
For an outline of past/future changes refer to: [CHANGELOG](CHANGELOG.md)
|
|
|
|
## Tested against
|
|
|
|
- Basic 1.0.8.4
|
|
- Banana 2.0.6.4
|
|
- Potato 3.0.2.4
|
|
|
|
## Requirements
|
|
|
|
- [Voicemeeter](https://voicemeeter.com/)
|
|
- Python 3.10 or greater
|
|
|
|
## Installation
|
|
|
|
`pip install voicemeeter-api`
|
|
|
|
## `Use`
|
|
|
|
Simplest use case, use a context manager to request a Remote class of a kind.
|
|
|
|
Login and logout are handled for you in this scenario.
|
|
|
|
#### `__main__.py`
|
|
|
|
```python
|
|
import voicemeeterlib
|
|
|
|
|
|
class ManyThings:
|
|
def __init__(self, vm):
|
|
self.vm = vm
|
|
|
|
def things(self):
|
|
self.vm.strip[0].label = "podmic"
|
|
self.vm.strip[0].mute = True
|
|
print(
|
|
f"strip 0 ({self.vm.strip[0].label}) mute has been set to {self.vm.strip[0].mute}"
|
|
)

|
|
info = (
|
|
f"bus 3 gain has been set to {self.vm.bus[3].gain}",
|
|
f"bus 4 eq has been set to {self.vm.bus[4].eq.on}",
|

|
|
KIND_ID = "banana"
|

|
|
with voicemeeterlib.api(KIND_ID) as vm:
|
|
do = ManyThings(vm)
|
|
do.things()
|
|

|
|
|

|
|
|
|
```python
|
|
print(vm.midi.get(12))
|
|
```
|
|
|
|
get() may return None if no value for requested key in midi cache
|
|
|
|
### Multiple parameters
|
|
|
|
- `apply`
|
|
Set many strip/bus/macrobutton/vban parameters at once, for example:
|
|
|
|
```python
|
|
vm.apply(
|
|
{
|
|
"strip-2": {"A1": True, "B1": True, "gain": -6.0},
|
|
"bus-2": {"mute": True, "eq": {"on": True}},
|
|
"button-0": {"state": True},
|
|
"vban-in-0": {"on": True},
|
|
"vban-out-1": {"name": "streamname"},
|
|
}
|
|
)
|
|
```
|
|
|
|
Or for each class you may do:
|
|
|
|
```python
|
|
vm.strip[0].apply(mute: True, gain: 3.2, A1: True)
|
|
vm.vban.outstream[0].apply(on: True, name: 'streamname', bit: 24)
|
|
```
|
|
|
|
## Config Files
|
|
|
|
`vm.apply_config(<configname>)`
|
|
|
|
You may load config files in TOML format.
|
|
Three example configs have been included with the package. Remember to save
|
|
current settings before loading a user config. To set one you may do:
|
|
|
|
```python
|
|
import voicemeeterlib
|
|
with voicemeeterlib.api('banana') as vm:
|
|
vm.apply_config('example')
|
|
```
|
|
|
|
will load a user config file at configs/banana/example.toml for Voicemeeter Banana.
|
|
|
|
## Events
|
|
|
|
By default, NO events are listened for. Use events kwargs to enable specific event types.
|
|
|
|
example:
|
|
|
|
```python
|
|
import voicemeeterlib
|
|
# Set event updates to occur every 50ms
|
|
# Listen for level updates only
|
|
with voicemeeterlib.api('banana', ratelimit=0.05, ldirty=True}) as vm:
|
|
...
|
|
```
|
|
|
|
#### `vm.observer`
|
|
|
|
Use the Subject class to register an app as event observer.
|
|
|
|
The following methods are available:
|
|
|
|
- `add`: registers an app as an event observer
|
|
- `remove`: deregisters an app as an event observer
|
|
|
|
example:
|
|
|
|
```python
|
|
# register an app to receive updates
|
|
class App():
|
|
def __init__(self, vm):
|
|
vm.observer.add(self)
|
|
...
|
|
```
|
|
|
|
#### `vm.event`
|
|
|
|
Use the event class to toggle updates as necessary.
|
|
|
|
The following properties are available:
|
|
|
|
- `pdirty`: boolean
|
|
- `mdirty`: boolean
|
|
- `midi`: boolean
|
|
- `ldirty`: boolean
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.event.ldirty = True
|
|
|
|
vm.event.pdirty = False
|
|
```
|
|
|
|
Or add, remove a list of events.
|
|
|
|
The following methods are available:
|
|
|
|
- `add()`
|
|
- `remove()`
|
|
- `get()`
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.event.remove(["pdirty", "mdirty", "midi"])
|
|
|
|
# get a list of currently subscribed
|
|
print(vm.event.get())
|
|
```
|
|
|
|
## Remote class
|
|
|
|
`voicemeeterlib.api(KIND_ID: str)`
|
|
|
|
You may pass the following optional keyword arguments:
|
|
|
|
- `sync`: boolean=False, force the getters to wait for dirty parameters to clear. For most cases leave this as False.
|
|
- `ratelimit`: float=0.033, how often to check for updates in ms.
|
|
- `pdirty`: boolean=False, parameter updates
|
|
- `mdirty`: boolean=False, macrobutton updates
|
|
- `midi`: boolean=False, midi updates
|
|
- `ldirty`: boolean=False, level updates
|
|
|
|
Access to lower level Getters and Setters are provided with these functions:
|
|
|
|
- `vm.get(param, is_string=False)`: For getting the value of any parameter. Set string to True if getting a property value expected to return a string.
|
|
- `vm.set(param, value)`: For setting the value of any parameter.
|
|
|
|
Access to lower level polling functions are provided with these functions:
|
|
|
|
- `vm.pdirty()`: Returns True if a parameter has been updated.
|
|
- `vm.mdirty()`: Returns True if a macrobutton has been updated.
|
|
- `vm.ldirty()`: Returns True if a level has been updated.
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.get('Strip[2].Mute')
|
|
vm.set('Strip[4].Label', 'stripname')
|
|
vm.set('Strip[0].Gain', -3.6)
|
|
```
|
|
|
|
