Requirements

• Voicemeeter
• Python 3.11 or greater

Installation

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

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
• mc, k: boolean
• comp, gate: float, from 0 to 10
• limit: int, from -40 to 12
• A1 - A5, B1 - B3: boolean
• eq: boolean
• label: string
• device: string
• sr: int

example:

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:

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:

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:

# 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:

vm.command.restart()
vm.command.showvbanchat = true

Multiple parameters

• apply Set many strip/bus/macrobutton/vban parameters at once, for example:

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:

vm.strip[0].apply(mute: true, gain: 3.2, A1: true)
vm.vban.outstream[0].apply(on: true, name: 'streamname', bit: 24)

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:

vm.get('Strip[2].Mute')
vm.set('Strip[4].Label', 'stripname')
vm.set('Strip[0].Gain', -3.6)

Config Files

vm.apply_config('config')

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:

import voicemeeterlib
with voicemeeterlib.api('banana') as vm:
    vm.apply_profile('config')

will load a config file at configs/banana/config.toml for Voicemeeter Banana.

Run tests

To run all tests:

pytest -v
