Why Mixlet?

Sometimes you just need your audio to behave.

Screen sharing a synth? Teaching a remote lesson? Sending a demo into Slack? Mixlet is designed to make the obvious routing feel obvious: choose your mic, add your Mac audio, send the combined mix to the app you’re using.

🎙️

Mic + Mac audio

Blend your microphone with sounds from your Mac so people can hear both you and what you’re playing.

🟠

Menu bar first

Keep Mixlet out of the way until you need it. Open, route, adjust, close. It stays ready.

🔊

Virtual output

Add Mixlet Piper when you need a virtual device that other apps can select as an audio source.

Fast setup

Designed for the moment before a call, workshop, stream or synth demo — not an afternoon of routing diagrams.

🎚️

Simple levels

Friendly controls for balancing voice and system sound, with meters that tell you what’s happening.

🧡

Small by design

A compact utility with a warm personality: useful, lightweight and not trying to become a full studio.

Typical setup

Three tiny steps.

  1. 1

    Pick your microphone.

  2. 2

    Add your Mac audio.

  3. 3

    Send the mix to your output, or install Mixlet Piper when another app needs to hear it.
