1-bit 1.7, First Light

1-bit 1.7 is on the App Store. Ask Siri to play your library, a Home screen of automatic mixes your own bridge builds from your listening history, performer credits, and a new DAC profile — plus an optional way to pull richer artwork and artist notes. Bridge 0.1.7 ships alongside with Smart Mixes and on-device audio analysis. Same bit-exact DSD over DoP, no transcoding.

Updated

1-bit 1.7 is on the App Store. Same URL, new build, free update.

The easter-egg card in Settings → About drops back to a single line this release, after the little poems of 1.4 and 1.5. This one just reads “First Light.” Two things in 1.7 earn it: 1-bit can finally hear you — say “play … on 1-bit” and Siri takes it from there — and it wakes up to a Home screen of mixes your own bridge has quietly assembled from what you’ve been listening to.

What’s new

Siri — “play … on 1-bit”Ask for an album, an artist, a playlist, or your downloads by name — at home, on the Lock Screen, or in the car — and 1-bit plays it from your own library. Apple does the listening; the app only ever receives the resolved request (which record you asked for) and starts the music. No voice data comes to me, and nothing about what you play is handed back to Siri.
A Home screen that mixes itselfHeavy Rotation, Drive Mix, Wind Down, an Auto Mix that sequences by musical key, a mix that shifts with the time of day. They’re built by your own bridge, once a day, from the listening history you chose to share back in 1.5 — server-side, on hardware you run, never touching a machine of mine. The Home tab only shows up when there’s something in it.
Performer creditsThe tag parser now reads performer and involved-people frames — the session players, the engineer, the “with” line — not just the headline artist. If your files carry the credits, the people behind the record finally show up in the metadata. All parsed on-device from tags you already have.
CarPlay recents & a new DACCarPlay keeps your recent searches and recently-played albums and playlists on the home screen, so you pick up where you left off without digging — kept on the phone, never uploaded. And the profiled-DAC list gains a Mytek Brooklyn DAC+, with its own curated resync timing and DSD ceiling.

A quieter addition: richer artwork and artist notes

1.7 also adds an optional way to get richer metadata. Turn on Atlas for a bridge and 1-bit can pull higher-resolution square cover art, artist biographies, and short album descriptions for whatever you’re looking at. It’s off by default, you flip it on per bridge, and it only ever fetches public music information.

Let me be straight about it, because it’s a first for this app: Atlas is a small service I run — the first server in the whole 1-bit story that’s actually mine, after two years of the app only ever talking to hardware you own. When it’s on, the app proves it’s a genuine, unmodified install (Apple’s App Attest) and sends nothing but the MusicBrainz ID of the album or artist on screen. To keep it from being abused, Atlas holds a minimal record — an attestation key and the IP it last saw — that isn’t tied to your identity, is never used for tracking, and keeps no log of what you looked up. It’s deletable on request, and the service is self-hostable if you’d rather it never leave your own boxes.

The one visible consequence of all this: because Atlas can be switched on, this release’s App Store privacy card now lists an Identifiers item — used only for app functionality and fraud prevention, not linked to your identity, not used for tracking. With Atlas off, which is how it ships, 1-bit still collects nothing at all. The privacy policy spells out every line of it.

And on the bridge side

Bridge 0.1.7 ships alongside — same v1 wire protocol, with the new endpoints added additively.

Three themes. Smart Mixes are the rotating, server-generated playlists behind that new Home screen — rebuilt once a day from your opt-in listening history and the analysis below, served only to your own paired devices. On-device audio analysis lets the bridge decode your tracks locally (with sox, ffmpeg as a fallback) to compute a peak waveform for the iOS scrubber, R128 loudness, and an estimated key and tempo — all of it on the bridge host, nothing about your audio going anywhere. And the optional Atlas path: by default your app fetches the richer metadata and hands it to the bridge to cache for your other devices, with a bridge-direct bulk-harvest mode for big libraries — both off by default. Full release notes on the bridge releases page.

Same audio path

No transcoding. No resampling. No mixer in the path. DSD goes out as DoP to your USB DAC; PCM goes out at the file’s native sample rate. Siri only tells the app what to play; the mixes are lists of your own tracks; Atlas only ever touches metadata, never the audio. The bytes that reach your DAC are the bytes in your files.

The unromantic version

If you have 1-bit installed: open the App Store and tap update. Your SMB shares, bridge pairings, and Settings carry over. Siri asks permission the first time you use it; the Home mixes appear on their own once you’re running a bridge with Smart Mixes on; Atlas and everything else new stays off until you decide to turn it on.

If you’re new: it’s a free download, iPhone or iPad, iOS 26.1 or later. Bring a NAS or a bridge, a USB DAC for DSD, and music you actually like.
