Go Reference

A Go Wrapper for the Voicemeeter API

For an outline of past/future changes refer to: CHANGELOG

Tested against

  • Basic 1.1.1.1
  • Banana 2.1.1.1
  • Potato 3.1.1.1

Requirements

Installation

Initialize your own module then go get

go mod init github.com/x/y
go get github.com/onyx-and-iris/voicemeeter/v2

Use

main.go

package main

import (
	"fmt"
	"log"

	"github.com/onyx-and-iris/voicemeeter/v2"
)

func main() {
	vm, err := vmConnect()
	if err != nil {
		log.Fatal(err)
	}
	defer vm.Logout()

	vm.Strip[0].SetLabel("rode podmic")
	vm.Strip[0].SetMute(true)
	fmt.Printf("Strip 0 (%s) mute was set to %v\n", vm.Strip[0].Label(), vm.Strip[0].Mute())
}

func vmConnect() (*voicemeeter.Remote, error) {
	vm, err := voicemeeter.NewRemote("banana", 20)
	if err != nil {
		return nil, err
	}

	err = vm.Login()
	if err != nil {
		return nil, err
	}

	return vm, nil
}

voicemeeter.NewRemote(<kindId>, <delay>, opts ...Option)

kindId

Pass the kind of Voicemeeter as an argument. kindId may be:

  • basic
  • banana
  • potato

delay

Pass a delay in milliseconds to force the getters to wait for dirty parameters to clear.

Useful if not listening for event updates.

voicemeeter.WithTimeout(timeout int)

Set a login timeout, defaults to 2 seconds. For example to set it to 1s:

voicemeeter.NewRemote("banana", 20, voicemeeter.WithTimeout(1))

voicemeeter.WithBits(bits int)

Override the type of Voicemeeter GUI to launch on 64 bit systems. For example, to force 32 bit GUI:

voicemeeter.NewRemote("banana", 20, voicemeeter.WithBits(32))

Remote Type
