Frequently asked questions

Do I need an internet connection?
No. Your iPhone and PC just need to be on the same Wi-Fi network. Audio travels over your local network only — it never touches the internet.
Can someone else send audio to my PC?
No. Connecting requires the PIN (or QR code) shown on your PC's screen. With the wrong PIN, audio is rejected.
How much delay is there?
Roughly 50–150 ms depending on the mode. Balanced (~100 ms) is plenty for video calls; pick low-latency mode when timing matters most.
Which OS versions are supported?
On desktop, macOS 13 or later (Apple Silicon and Intel) and Windows 10/11 (64-bit, beta). On mobile, iOS 16 or later.
How do I connect my iPhone to my PC?

Make sure your iPhone and PC are on the same Wi‑Fi network, then:

1. Install and open Microphone Link on your PC (Mac or Windows). It shows a QR code, a PIN, and the PC's IP address.
2. Install Microphone Link on your iPhone and open it.
3. On the iPhone, tap Scan QR and point it at the code on your PC — or pick your PC from the nearby list and type the PIN, or enter the IP manually.
4. Tap Start and allow microphone access. Your iPhone is now a wireless mic for the PC.

The PC app shows a live input level, so you can watch it move as you speak to confirm the connection.

After connecting, how do I use it as my microphone?

Once your iPhone is connected, a microphone called "Microphone Link" appears on your PC. Select it wherever you'd pick a mic:

In your app (Zoom, Discord, Teams, OBS, Google Meet, …): open its audio/mic settings and choose Microphone Link from the input list. This is usually all you need — each app remembers its own mic choice.

Or make it the system default so every app uses it automatically:

• Windows: Settings → System → Sound → Input → choose Microphone Link.
• macOS: System Settings → Sound → Input → choose Microphone Link.

The PC app shows a live input level so you can confirm your voice is coming through. Tip: use the Test button in the PC app to hear yourself before a call.

"Microphone Link" doesn't appear, or there's no sound — what should I check?

Run through these in order:

1. Same Wi‑Fi? Both devices must be on the same network. Guest networks and some office/hotel Wi‑Fi block device‑to‑device traffic — try a home network or a phone hotspot.
2. PC app running and connected? The engine must be running (the app shows "Engine running") and the iPhone must show Connected.
3. Right PIN? The PIN changes each time the PC app launches — use the one currently shown, or re‑scan the QR code.
4. Selected the right mic? Make sure your app (or Windows/macOS Sound settings) has Microphone Link chosen as the input.
5. Started streaming? Tap Start on the iPhone and grant microphone permission; check it isn't muted.
6. Switched Wi‑Fi? If your PC changed networks, its IP changed too — re‑scan the QR code or re‑pick the PC from the nearby list.

Which quality mode should I pick?

The iPhone app offers three modes — pick based on what matters most:

• Low latency — the fastest, lowest delay. Best for gaming, live monitoring, or anything where timing is critical.
• Balanced (default) — the everyday sweet spot. Great for video calls and meetings.
• High quality — the richest audio for recording or streaming, at a slightly higher delay.

You can switch modes anytime; the change takes effect immediately.

How do I uninstall it on macOS?

Microphone Link installs a system audio driver, so dragging the app to the Trash leaves the virtual microphone behind. To remove it completely, do one of these:

Easiest — from the app: click the microphone icon in the menu bar and choose Uninstall Microphone Link…. It removes the driver and the app in one step.

Already trashed the app? Paste this into Terminal and enter your Mac password:

sudo rm -rf /Library/Audio/Plug-Ins/HAL/MicLink.driver && sudo killall coreaudiod

Or download Uninstall Microphone Link, unzip it, and double-click the app. It's notarized by Apple, so it opens without a security warning.

How do I uninstall it on Windows?

Open Settings → Apps → Installed apps, find Microphone Link, and choose Uninstall (or use the uninstaller in the Start menu folder). This removes the app and its background engine.

The installer also adds a virtual audio device (built on VB‑Cable) that provides the "Microphone Link" microphone. If you want that removed too, uninstall VB‑Cable the same way from Settings → Apps.

Is my audio private?

Yes. Audio streams directly from your iPhone to your PC over your local Wi‑Fi — it never leaves your network and never touches our servers (we don't run any). There are no accounts and no sign‑in. Pairing requires the PIN or QR code shown on your PC, so a stranger on the same network can't send audio to your PC.
