Space without a wandering center
Mid/Side width opens high-side information while mono-bass protection keeps low frequencies anchored.
Native sound shaping for macOS
Listen longer.
Adjust less.
NAGI gently opens the stage, gives existing bass more depth, keeps vocals present and takes the hard edge off bright recordings.
No room simulation. No remote audio processing. Just a calm, reversible DSP between your Mac and the music.

01 / Intention
Easy listening, without the easy-listening cliché
The music can stay vivid.
The presentation can feel calmer.
Long sessions often become tiring before the music becomes uninteresting. The stage feels narrow. Upper bass keeps knocking. Vocals press forward. Sibilance asks for attention.
NAGI changes that presentation conservatively. It reshapes audio already present in the stream; it never claims to create missing fundamentals, separate stems or make unsafe volume safe.
02 / The signature
One signature by design
Open. Deep.
Gently refined.
Nagi is not an empty preset slot. It is the product: one balanced result you can turn on before you learn a single control.
Depth without invented sub-bass
Bass Character and Bass Bloom move attention away from short upper-bass impact toward rounder low-frequency body already in the recording.
Clarity without a blunt boost
Center-only Vocal Focus and a bounded Sibilance Guard protect intelligibility while calming the sharpest moments.
03 / Character
Semantic controls, not an EQ lesson
Choose a feeling.
Keep the music.
Nagi is the free Signature. Warm, Smooth, Deep, Vivid and Wide are NAGI PRO presets: curated trajectories through one coherent sound engine.

NAGI PRO · One sound model, every control in agreement
Move one idea.
See the whole sound respond.
Full Studio is part of NAGI PRO. Sound Space, the tonal Character Field and equalizer stay linked; bass, vocal and sibilance controls refine the same result.
The 10× edge is intentionally dramatic, so you can hear where width helps and where the recording asks you to come back.

Drag the field or a control. Click once to arm precise two-finger trackpad adjustment without accidental scrolling.
Custom when it becomes yours
Change any preset value and NAGI marks the result Custom, ready to save as a local listening profile.
Reference that stays with you
Sample sounds and generated tones continue across Studio tabs, so the comparison survives the adjustment.

Up to 3 outputs Multi-Output Crossover
Let every speaker
do less, better.
Connect up to three compatible outputs to your Mac, choose what each one should reproduce, then balance each selected output independently.
NAGI exposes Full Range, Bass, Mids and Treble roles with adjustable cutoffs. Route availability and achievable synchronization still depend on each device, driver and transport.

Detail above.
Weight below.
When macOS exposes compatible outputs, send Treble to your headphones and Bass to larger desktop drivers. The headphones carry the fine-detail lane; the speakers carry the selected low-frequency lane.
HeadphonesTreble · above 3.2 kHz
Desktop speakersBass · below 120 Hz
With suitable hardware and cutoffs, moving demanding low frequencies away from smaller drivers can leave more usable headroom and a calmer presentation.
02 Use the system you already own
Make the external system
your bass foundation.
Keep mids and highs on the Mac or headphones, then route only the lower band to a connected hi-fi system, powered speaker or subwoofer.
EXTERNAL SYSTEM · OUTPUT LEVEL+2.0 dB
Trim this output without changing the other two routes.
Independent level control helps compensate for devices with different sensitivity, amplifier gain or listening distance.
03 One source, simultaneous outputs
One mix.
Three visible lanes.
NAGI processes the mix locally, splits it into frequency lanes and sends those lanes to as many as three selected devices at the same time.
BAND IN−6
DEVICE OUT−9
BAND IN confirms that the selected frequency range contains energy. DEVICE OUT shows what reaches that output after its own level trim.
07 / NAGI PRO
The signature is the beginning

Precise by choice.
The free Nagi Signature, compact menu controls, truthful Active / Passive control and Sound Check come first. PRO adds five more character presets, Full Studio controls, custom profiles and connected-output routing.

Local by design
Your listening
stays yours.
NAGI processes system audio locally in memory. It does not save recordings, write audio files, upload or share the audio you listen to. Presets and preferences remain on your Mac unless you choose to remove the app’s local data.
Acoustic Sync requests microphone access only when you start calibration. Temporary measurement samples remain in memory and are discarded after the estimate; they are not saved or uploaded.
Purchases are processed by Apple. NAGI receives only StoreKit product and verified entitlement status; it does not receive or store payment-card details. If you contact support, Kodawari uses the information in your message only to respond to that request.
Effective 28 August 2026. Privacy questions: info@kodawari.app.
