SoundPin

Pins your microphone.

When you connect AirPods or a Bluetooth headset, macOS switches your microphone. SoundPin switches it straight back – and can make it louder, too.

For macOS 14 or later · €5.99

You’re recording. Your AirPods connect, and from now on macOS records through their microphone instead. Muffled, quiet, mid-sentence. SoundPin won’t let that happen.

What you get.

One click in the menu bar.

Choose your microphone from the pin menu – and your speakers, if you like. Checkmarks show what SoundPin keeps. No window, no Dock icon.

Back in under a second.

When AirPods or a headset connect, SoundPin switches straight back to your microphone. If you unplug it, macOS chooses – until it’s back.

  1. AirPods Pro connected
  2. macOS switches to AirPods Pro
  3. SoundPin switches back to RØDE PodMic USB

Your headphones keep sounding great.

When macOS uses the microphone of Bluetooth headphones, it drops them into a muffled headset mode. With SoundPin, the microphone stays on your desk and your headphones keep full sound quality.

Louder, without clipping.

Too quiet even at full input level? SoundPin boosts your microphone by up to 18 dB and passes it on to any app as “SoundPin Mic”. A limiter keeps every peak below −1 dBFS.

Boost +12 dB Loudest peak −1.0 dBFS

Example: a quiet voice recording. Purple = caught by the limiter.

Pin your speakers, too.

Want sound to stay on your speakers when headphones connect? Pin them as well. Otherwise sound follows your headphones as usual.

Questions.

How do I stop my Mac from switching to the AirPods microphone?

macOS has no setting that keeps your microphone when headphones connect – it switches to their microphone every time. With SoundPin, you choose your microphone once in the menu bar. When AirPods or a headset connect, SoundPin switches straight back.

How can I make my Mac’s microphone louder?

If the input volume in System Settings is already at maximum, SoundPin boosts your microphone by up to 18 dB and passes it on to any app as “SoundPin Mic”. A limiter keeps every peak below −1 dBFS, so nothing clips.

Does SoundPin work with my app?

SoundPin sets the default microphone in macOS, and most apps follow it. If an app has a fixed microphone selected, choose your microphone there – or “SoundPin Mic” if you use boost.

Why does SoundPin ask for my password?

Only for boost. “SoundPin Mic” is a virtual microphone – an audio driver – and macOS installs drivers only with an administrator password. Sound drops out for a moment while the audio system restarts.

Why isn’t SoundPin on the Mac App Store?

Apple doesn’t allow apps with a virtual microphone there. That’s why you get SoundPin directly from this site.

How do I uninstall SoundPin?

If you used boost, choose “Remove Virtual Microphone…” from the menu first. Then quit SoundPin and move it to the Trash.
