The path to the DAC

Three ways out. Start with Shared.

Audiophile software loves jargon. We don’t. If you are unsure, leave Shared on — that is the daily driver, on every device.

Shared
◇

Everyday listening — recommended

Plays like any other app. Calls, YouTube, speakers, Bluetooth, AirPlay still work. This is the default, and the only honest path for anything that is not a dedicated DAC.

Exclusive
◎

Bit-perfect into a USB DAC

Mac only, with an external DAC. Audio Harbor takes over the DAC so the file’s sample rate stays as-is. Other apps go silent; set the volume on the DAC. DSD files are converted to PCM.

DoP
☾

Exclusive, plus real DSD

Mac only. Everything Exclusive does — and DSF, DFF, and SACD ISO (including DST) reach the DAC as real DSD via DoP. Pick it only if your DAC plays DSD. No separate DSD setting: the output mode decides.

No external DAC connected? Exclusive and DoP grey out and Shared takes over — plug the DAC back in and your choice returns on its own. Pick the device in Settings — music to the DAC, system sounds stay on the Mac speakers — and switch device or mode while the song plays. Effects on the rack keep the DAC exclusive at the file’s rate (Exclusive · FX), but processed sound is not bit-perfect — only the empty rack is, and we will not pretend otherwise. More in the FAQ.


Simple by design

Music in under a minute

No server. No login. Point at the folders you already keep, and play.

01
⌘

Add a directory

Connect the discs, NAS mounts, or iCloud folders that hold your library. Audio Harbor indexes them locally — titles, artwork, search — and stays out of the cloud.

02
▶

Play from the catalogue

Browse by album, artist, or folder. Queue an album onto the Deck. Gapless PCM. The format badge tells you what is actually leaving the app.

03
◎

Exclusive when the DAC is ready

On Mac, with a USB DAC you trust, switch Output to Exclusive. Sample rate follows the file. Built-in speakers stay on Shared — as they should.


The room, not a dashboard

Ink chassis. Walnut. Filament amber.

The player is a listening room, not a mixer. Catalogue, Deck, Settings. Large artwork. Analog VU when the music is moving. Nothing competing for the downbeat.

The music stays on the Mac. Your iPhone or iPad steers.

Deck, Catalogue, and Settings — the same three tabs as on the Mac. Browse and search from the couch, file songs into playlists and labels, change Output on the Mac, and set the DAC's own level with the volume buttons so the file stays bit-perfect. Local network only, no account, free.

One job

Play local high-res audio correctly

Features earn their place. If it does not help you hear the file, it does not sit on the Deck.

▤

Your folders

Security-scoped bookmarks so the library survives a restart. Incremental index, search, rebuild when you ask — not a background circus.

◎

Bit-perfect on Mac

Hog mode, sample-rate match, 24-bit HAL path. Exclusive is for a known DAC. We will not silently resample on that path.

1

DSD without the drama

Output DoP sends DSD as DoP to a DSD DAC. Every other path gets a clean PCM conversion — flat to 25 kHz, with a level setting so it plays as loud as DoP — labelled in the UI. No fake 1-bit into laptop speakers.

◈

AU and AUv3 on the Deck

AU and AUv3 inserts on the Deck. The plugins you already own — EQ, room correction, headphone correction — sit on the player. See the rack.

≡

Catalogue, not a feed

Album, artist, folder, playlists, queue. M3U / M3U8 playlists in from foobar, VLC, Roon, or Music — and back out. Lock screen and media keys. The music is yours; we do not recommend a lifestyle.

○

No account

No streaming services. No DRM Apple Music library. No telemetry of what you play. Privacy is the default, not a setting.

⌁

Network players

On Mac, UPnP / DLNA players such as a Devialet Expert sit under Network Players, separate from This Host. Radios switch with the pick: Shared / Exclusive / DoP for a USB DAC; Wi‑Fi friendly, Full, or DSD, SACD, DoP when the player lists DSD — then those files go untouched. Or share the library, and a DLNA app on your iPhone plays it.


Audio Units

AU plugins. In the player.

Audio Harbor is a host. Load the AU and AUv3 effects you already use in Logic, GarageBand, or AUM — as inserts on the Deck, while the record plays.

Mac

AU and AUv3

Any stereo Audio Unit effect — AUv3 extensions and classic AU components. The same units other Apple hosts see. Add from the rack, open the plugin’s own editor, keep the settings after quit.

Out of process

Crash-safe

AUv3 effects run outside the player. Classic AUs that are not sandbox-safe — most commercial ones — run in macOS’s own Audio Unit host, not inside Audio Harbor. A plugin that misbehaves takes itself down, not your listening.

Honest path

Exclusive · FX

With Exclusive or DoP on a DAC, a loaded rack keeps the DAC to itself at the file’s sample rate — no system mixer, no macOS resampling. Only the plugin changes the sound. Clear the inserts when you want the DAC bit-perfect or DSD via DoP again.

+

Add from the Deck

The rack sits under Now Playing. Search the installed units, drop one in, reorder, bypass. No separate “FX app.”

◻

The plugin’s own UI

Edit opens the AU view — knobs, graphs, whatever the vendor shipped. Not a generic parameter list unless that is all the unit has.

◎

Settings stay

Chain, bypass, and plugin state are stored with the app. Quit and reopen: the same EQ, the same room correction.

Stereo inserts only. Some vendor AUs expect a DAW host and will refuse a player graph — we drop those rather than crash. Waves-class units are the usual example.


Formats

What it will play

The files on your disks — not a converter suite in the main path.

PCM, as written

FLAC · ALAC · WAV · AIFF · AAC/M4A · MP3. Gapless where the format allows. Exclusive keeps 24-bit PCM bit-perfect on Mac.

DSD, with a label

DSF, DFF, and SACD ISO stereo — including DST-compressed discs. Output DoP sends real DSD; Shared and Exclusive convert to PCM. The path says which one you are on.

Not in the main path

No converter suite, no 768 kHz upsampling theatre, no Qobuz/Tidal. Those dilute the local-first promise.

What the badge is for

The Deck shows the format and the path — Shared, Exclusive, DoP, Exclusive · FX, or Shared · FX — so you are never guessing what left the app.


One product

Mac leads. The pocket follows.

The Mac ships first, with a free remote for iPhone and iPad. An iPad player is planned. None of it is available yet — we say that on the box, not in a footnote.

Lead platform

Mac

Daily driver. Folder watch, Exclusive hog + rate match, DoP into a USB DAC, AUv3 on the Deck, keyboard, media keys.

Planned, not yet released

iPad

The same Deck and library, laid out for a larger canvas. Shared playback, AUv3 inserts on the rack. Not in the first release — until then the iPad works as the remote.

Next, free · not yet released

iPhone & iPad remote

The music stays on the Mac and its DAC; your iPhone or iPad steers with Deck · Catalogue · Settings. Browse, search, queue, play, add to playlists and labels, change Mac Output — and set the DAC’s own volume with its volume buttons, still bit-perfect. Local network only, no account.

Your folders. Your files. No cloud required.

What it costs

Free to install. One payment, once.

No subscription, no account, no tier above this one. You try the whole app first and decide afterwards.

Download

Free

Anyone with an Apple Account can install Audio Harbor. Nothing to buy at the door, no voucher, no unlock before the download.

First seven days

The whole app

Every feature, from the first time you open it. No watermark, no nag screen, nothing held back. Settings shows the days you have left.

After that

€17.90 once

A one-time unlock to keep playing. It follows your Apple Account, so Restore Purchases brings it back on another Mac. Browsing the catalogue stays free either way.

Price shown for the euro storefront. Apple sets the equivalent in other regions, and the app always shows the real price from the App Store rather than a number typed into this page. Audio Harbor is not on the Mac App Store yet — the listing is in progress.

Put the library in harbor.

macOS first — with a remote for iPhone and iPad, and an iPad player later. Local files, AUv3 on the Deck, no account. Source is on GitHub while we finish the Mac App Store listing.
