## Installation
|
|
|
|
### `Pip`

|
|
|
|
`pip install voicemeeter-api`
|

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}) has been set to {self.vm.strip[0].mute}"
|
|
)
|
|
|
|
def other_things(self):
|
|
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}",
|
|
)
|
|
self.vm.bus[3].gain = -6.3
|
|
self.vm.bus[4].eq = True
|
|
print("\n".join(info))
|
|
|
|
|
|
def main():
|
|
with voicemeeterlib.api(kind_id) as vm:
|
|
do = ManyThings(vm)
|
|
do.things()
|
|
do.other_things()
|
|
|
|
# set many parameters at once
|
|
vm.apply(
|
|
{
|
|
"strip-2": {"A1": True, "B1": True, "gain": -6.0},
|
|
"bus-2": {"mute": True},
|
|
"button-0": {"state": True},
|
|
"vban-in-0": {"on": True},
|
|
"vban-out-1": {"name": "streamname"},
|
|
}
|
|
)
|
|
|
|
|
|
if __name__ == "__main__":
|
|
kind_id = "banana"
|
|
|
|
main()
|
|
```
|
|
|
|
Otherwise you must remember to call `vm.login()`, `vm.logout()` at the start/end of your code.
|
|
|
|
## `kind_id`
|
|
|
|
Pass the kind of Voicemeeter as an argument. kind_id may be:
|
|
|
|
- `basic`
|
|
- `banana`
|
|
- `potato`
|
|
|
|
## `Available commands`
|
|
|
|
### Channels (strip/bus)
|
|
|
|
The following properties exist for audio channels.
|
|
|
|
- `mono`: boolean
|
|
- `mute`: boolean
|
|
- `gain`: float, from -60 to 12
|
|

|
|
- `eq`: boolean
|
|
- `label`: string
|
|
- `device`: string
|
|
- `sr`: int
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.strip[3].gain = 3.7
|
|
print(strip[0].label)
|
|
|
|
vm.bus[4].mono = true
|
|
```
|
|
|
|
### Macrobuttons
|
|
|
|
Three modes defined: state, stateonly and trigger.
|
|
|
|
- `state`: boolean
|
|
- `stateonly`: boolean
|
|
- `trigger`: boolean
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.button[37].state = true
|
|
vm.button[55].trigger = false
|
|
```
|
|
|
|
### Recorder
|
|
|
|
The following methods are Available
|
|
|
|
- `play()`
|
|
- `stop()`
|
|
- `pause()`
|
|
- `record()`
|
|
- `ff()`
|
|
- `rew()`
|
|
The following properties accept boolean values.
|
|
- `loop`: boolean
|
|
- `A1 - A5`: boolean
|
|
- `B1 - A3`: boolean
|
|
Load accepts a string:
|
|
- `load`: string
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.recorder.play()
|
|
vm.recorder.stop()
|
|
|
|
# Enable loop play
|
|
vm.recorder.loop = True
|
|
|
|
# Disable recorder out channel B2
|
|
vm.recorder.B2 = False
|
|
|
|
# filepath as raw string
|
|
vm.recorder.load(r'C:\music\mytune.mp3')
|
|
```
|
|
|
|
### VBAN
|
|
|
|
- `vm.vban.enable()` `vm.vban.disable()` Turn VBAN on or off
|
|
|
|
For each vban in/out stream the following properties are defined:
|
|
|
|
- `on`: boolean
|
|
- `name`: string
|
|
- `ip`: string
|
|
- `port`: int, range from 1024 to 65535
|
|
- `sr`: int, (11025, 16000, 22050, 24000, 32000, 44100, 48000, 64000, 88200, 96000)
|
|
- `channel`: int, from 1 to 8
|
|
- `bit`: int, 16 or 24
|
|
- `quality`: int, from 0 to 4
|
|
- `route`: int, from 0 to 8
|
|
|
|
SR, channel and bit are defined as readonly for instreams. Attempting to write to those parameters will throw an error. They are read and write for outstreams.
|
|
|
|
example:
|
|
|
|
```python
|
|
# turn VBAN on
|
|
vm.vban.enable()
|
|
|
|
# turn on vban instream 0
|
|
vm.vban.instream[0].on = True
|
|
|
|
# set bit property for outstream 3 to 24
|
|
vm.vban.outstream[3].bit = 24
|
|
```
|
|
|
|
### Command
|
|
|
|
Certain 'special' commands are defined by the API as performing actions rather than setting values. The following methods are available:
|
|
|
|
- `show()` : Bring Voiceemeter GUI to the front
|
|
- `shutdown()` : Shuts down the GUI
|
|
- `restart()` : Restart the audio engine
|
|
|
|
The following properties are write only and accept boolean values.
|
|
|
|
- `showvbanchat`: boolean
|
|
- `lock`: boolean
|
|
|
|
example:
|
|
|
|
```python
|
|
vm.command.restart()
|
|
vm.command.showvbanchat = true
|
|
```
|
|
|
|
### 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},
|
|
"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 profiles have been included with the package. Remember to save
|
|
current settings before loading a profile. To set one you may do:
|
|
|
|
```python
|
|
import voicemeeterlib
|
|
with voicemeeterlib.api('banana') as vm:
|
|
vm.apply_config('example')
|
|
```
|
|
|
|
will load a config file at configs/banana/config.toml for Voicemeeter Banana.
|
|
|
|
## `Base Module`
|
|
|
|
### Remote class
|
|
|
|
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)
|
|
```
|
|
|
|
### Run tests
|
|
|
|
To run all tests:
