MicMixer
MicMixer mixes your microphone, a voice changer and music into one virtual
microphone, and gives each of them its own push-to-talk rule. FiveM, Discord and
other apps that accept a single microphone see an ordinary input. You decide
what goes into it, and you can switch while you play.

What you can do with it
- Play music into a game without holding the game's push-to-talk key.
MicMixer's own push-to-talk gates your voice while the music keeps playing,
and MicMixer can hold the game's talk key for you whenever it sends.
- Switch to a voice changer with a key. Hold the hotkey for the modified voice,
from an app such as Voicemod or from MicMixer's own voices, and release it to
go back.
- Send a separate mix to OBS or Streamlabs. The secondary output plays mic and
music on an extra device with its own push-to-talk rule, so your stream hears
everything while the game hears only what you let through.
There is also a noise gate, music that lowers itself while you talk, an MP3
library with YouTube download, capture from apps such as Spotify, and a status
overlay for your screen and your stream. The manual describes
all of it.

Set up
MicMixer needs a virtual audio cable to play the mix into. The installer offers
to install VB-CABLE. With the zip or winget,
install it yourself.
- Start MicMixer and follow the setup guide that opens. It finds the cable and
helps you pick your microphone and hotkey.
- In FiveM, Discord, or your chat app, select the cable's output end as the
microphone: CABLE Output, or MicMixer Output if the installer named it.
- Click Enable in MicMixer.
