The signal chain.

What happens to the sound between your Mac and your speakers, in the order it happens. Each stage can be switched off on its own.

  1. System audioeverything your Mac plays, captured without a driver
  2. 10-band EQ31.5 Hz to 16 kHz, one band at a time
  3. Tonethree knobs: bass, mid, treble
  4. Deep Bassharmonics your speakers can play, instead of sub-bass they can't
  5. Voice Claritypresence up at 3 kHz, mud out at 300 Hz
  6. Widthmid and side pulled apart, centre left alone
  7. Room Fillingcrosstalk cancelled, so the image steps outside the speakers
  8. Reverba tail behind the sound, as short or as long as you want
  9. Saturationthe curve bends at the edges: harmonics, not volume
  10. Crossfeedeach ear hears a little of the other side, the way speakers work
  11. Auto-gainquiet tracks brought up to meet the loud ones
  12. Limiter1.3 ms of look-ahead holds the ceiling instead of clipping it
  13. Your speakersquit the app and the sound goes back exactly as it was

Three clicks, zero plumbing.

  1. Open the app

    Drag it to Applications and launch. It asks once for the standard System Audio Recording permission.

  2. Pick your output

    Speakers, headphones, AirPods, any device. The original signal is muted while the app runs, so you only hear the processed sound.

  3. Press Start

    Spotify, YouTube, games: everything plays through your tuning. Quit the app and normal sound returns by itself.

On your desk.

One window. The chain on the left, what it's doing to the sound on the right, and a Start button. Nothing is installed; quit and macOS sound returns by itself.

What's inside the chain.

Every effect has its own switch. Use one, use all, or start from a preset.

Correction

10-band parametric EQ

31.5 Hz to 16 kHz, ±18 dB per band, adjustable Q, draggable curve, plus bass / mid / treble knobs.

Psychoacoustic

Deep Bass

Generates harmonics from sub-bass your speakers can't physically reproduce; your brain fills in the fundamental.

Dialog

Voice Clarity

Presence lift at 3 kHz plus a mud cut at 300 Hz, for films with murmured dialog and for podcasts.

Speakers

Room Filling

Crosstalk cancellation that pushes the stereo image outside the physical speakers at the listening position.

Headphones

Crossfeed

Moves the sound out of your head and in front of you, the way speakers present it.

Safety

Look-ahead limiter

Holds the ceiling without clipping the waveform, so boosted EQ can't push the signal into distortion.

Straight answers, before you download.

It adds 30–50 ms of latency.

Fine for music; on lip-sync-critical video you may want to press Stop.

Nothing to break.

No system files, no settings changed: stop or delete the app and your macOS sound is exactly as before.

It needs macOS 14.4 or newer.

The native system-audio capture it's built on doesn't exist in older versions.

Bluetooth speakers work.

The app follows the device's own sample rate, so a 44.1 kHz Bluetooth speaker plays clean. The codec still adds latency you'd notice on video.

It is not room correction software.

No measurement mic, no calibration curves. This is creative tone-shaping.

Boosted EQ won't distort.

A look-ahead limiter sits at the end of the chain and holds the ceiling, so even a heavy bass boost can't clip the signal.

First launch takes one extra step: System Settings → Privacy & Security → Open Anyway.

A speaker can only play what it's handed.

I'm not an engineer and I don't mix. I just listen to a lot of music and I'm particular about how it sounds. Good speakers didn't get me there on their own, nothing was shaping what reached them. So this does.
