Setting up a Chord 2Go with an iPhone
How to play music from an iPhone to a Chord 2Go over your own network — bit-exact, no transcoding — using DLNA and a self-hosted 1-bit bridge. Plus the security caveat nobody mentions.

What I build
Two products live here: 1-bit, a bit-exact DSD & hi-res audio player for iPhone and iPad, and Sonogram, a WebGL visualizer that turns a song into an interactive 3D fingerprint. The blog is where I write about how they — and other things — actually work.
1-bit
Bit-exact DSD and hi-res playback from your NAS or bridge straight to a USB DAC — no transcoding, no account, no tracking. Free on iPhone and iPad.
Sonogram
Upload a track and watch it become an interactive 3D “sonic fingerprint” — DSP analysis rendered with Three.js, right in the browser.

How to play DSD on an iPhone
iPhones don't play DSD out of the box, and most apps quietly convert it to PCM. Here's what actually playing DSD takes — a USB DAC, DoP, the right file, and a player that gets out of the way.

1-bit 1.5, the one with Chord 2Go support
1-bit 1.5 is on the App Store. Play bit-exact to a Chord 2Go or any DLNA renderer on your network, back up your playlists to your own bridge, and keep a private listening history. Bridge 0.1.5 ships alongside with a DLNA MediaServer. Same DSD over DoP, no transcoding.

1-bit 1.4, the one that goes in the car
1-bit 1.4 is on the App Store. CarPlay browse + Now Playing on the head unit, offline downloads, an in-app log viewer, and an optional DSD-domain DSP chain. Bridge 0.1.4 ships alongside with public-mode hosting and CarPlay-optimized variants. Same bit-exact DSD over DoP, no transcoding.

1-bit 1.3, the one where we forgot to change the codename
1-bit 1.3 is on the App Store. Opportunistic background library scans, composer/conductor/work fields for classical, a Listening Tips guide, a refined cellular streaming gate — and an easter-egg card that still calls this version 'Too Late, Too Soon'. Bridge 0.1.3 ships alongside. Same bit-exact DSD over DoP, no transcoding.
