C·03 Control panel 10 features

All the control, in a single window.

Every feature an audiophile would ask for, built into an interface that stays out of your way.

01 eq

Stereo EQ

Equalize each ear separately. If you hear less on one side, or one speaker sits against a wall, you correct only that channel.

one ear at a time
02 ui

3 EQ modes

Start with three knobs. When you want more, move to ten bands or the full curve.

03 dynamics

Volume boost

Go past the macOS ceiling when a video was recorded too quietly. The limiter keeps the sound from breaking up as you push it.

04 plugins

Audio Unit plugins

Use the plugins you already bought outside the studio. Add a compressor and whispered film dialogue becomes audible without riding the volume every scene.

Per-app mixer

Turn the browser down without touching your music. Every app gets its own volume and its own mute.

06 input

Global shortcuts

Change preset or mute everything without dropping what you are doing.

07 window

Floating window

Lives in the menu bar, or stays on top while you work.

09 input

Virtual microphone

Your voice goes out already equalized on video calls. People hear you more clearly without you changing anything.

A local server inside the app so you can automate it. A Stream Deck button that switches to the night preset, a shortcut that mutes everything when a call starts, or the web panel to control the sound from your phone.

Recording and editing

Record your screen with the audio you can actually hear.

QuickTime does not capture system sound: it records your voice and leaves the rest silent. ZonaReq captures it, because it is already in the path. It records what is playing and your microphone at once, and the editor gets it finished without opening anything else.

H.26460 fpsdual audioeditor included
01

Record

A full screen or a single window, at 60 frames per second. System audio and the microphone land on separate tracks.

02

Edit

A timeline to trim, join and reorder clips. Auto zoom follows the cursor so people can see what you are doing.

03

Export

H.264, ready to share. The history keeps every recording in case you want to go back to one.

The free version records up to three minutes and the exported video carries a watermark.

Also in Chrome

ZonaReq Recorder: the same auto zoom, inside the browser.

A Chrome extension that records a tab, a window or the screen and zooms in where you click. Free up to three minutes; Pro with the licence you already have.
