Your HyperX mic,
properly on the Mac.

MicDeck gives HyperX USB microphones the controls macOS leaves out: gain, mute, headphone level, polar pattern, low cut and QuadCast S lighting. It also tunes your voice in about fifteen seconds.

MicDeck's main window: a mixer with mic gain and headphone faders, a device card, QuadCast S lighting controls with top and bottom colours, and a Voice card with an Optimise voice button.

What it does

Everything on the mic, from your menu bar.

MicDeck sits in the menu bar and only shows the controls your mic actually has. Change the mic and the window changes with it.

Gain and mute

A proper fader with a live level meter, and one-click mute. On newer mics it follows the mic's own knob and tap-to-mute.

Headphones and monitoring

Set headphone volume, and on mics that support it, the balance between hearing yourself and hearing your Mac.

Polar pattern

Switch between cardioid, stereo, omni and bidirectional on the QuadCast 2 S without reaching for the knob.

Low cut

Turn on the mic's built-in high-pass filter to take out desk thumps, fans and rumble.

QuadCast S lighting

Pick separate top and bottom colours and brightness. Your colours stay on for as long as MicDeck is in the menu bar.

Voice optimiser

Record a short test and MicDeck sets EQ, compression and noise reduction for your voice. Every app can use the result.

Optimise voice

Sound like you, only better.

Read one sentence and MicDeck listens for pops, harsh S sounds, mud, room noise and peaks, then builds a voice chain for you. It explains each choice, and you can A/B the result before you apply it.

The Optimise voice window: three steps (stay quiet, read the sentence, then say it loud), the test sentence, and a Start recording button.

Privacy

Your voice stays on your Mac.

MicDeck collects no data and makes no network connections. Microphone access drives the level meter and the voice optimiser. The test recording is kept in memory while you tune and is never saved or sent anywhere.
