BRIMSTONE CORE · BETA 1

Your music.
One library. One Core.

A private music system built around the collection you actually own — local media, Meridian/Sooloos, services, multiple editions and multiple rooms — without turning your library into a pile of duplicate folders.

Beta 1 is real software, not a mock-up. Core and Control are running today, with the architecture feature-frozen while we polish, validate hardware and close the remaining defects.

THE LIBRARY, DONE PROPERLY

One album should still be one album.

Core separates the music from where it happens to be stored. A second copy does not become a second album. A genuine remix, remaster or alternate release stays a real edition.

01

Albums, editions & copies

Multi-disc sets stay together. Alternate mixes and remasters remain distinct. Identical copies across Core and Sooloos are counted as copies, not clutter.

02

Artwork that stays put

Selected artwork is stored locally against stable album identity. Metadata edits, rescans and restarts do not throw your covers away.

03

Your metadata, your call

MusicBrainz, Cover Art Archive, Discogs and source metadata help; manual choices remain authoritative when a database gets it wrong.

CONTROL

One interface for the whole system.

Control is the native Brimstone app for browsing the unified library, choosing rooms and outputs, managing metadata, importing media and controlling playback.

  • macOS Beta 1 available now
  • Shared iPhone/iPad Swift build compiling from the same source family
  • Standalone, Sooloos and Core capability modes without maintaining three different apps
  • Core Web provides the same system from a browser

Your Music

SOURCE TO DAC, WITHOUT THE FAIRY DUST

Core tracks what actually happens to the audio.

Every playback path is resolved as a complete capability chain. If a transport or DAC limits the source, Core reports the conversion and the component that caused it instead of claiming the source format reached the speakers unchanged.

01SourceMaster / stream
02CorePolicy / processing
03TransportUSB / HDMI / network
04EndpointRenderer / room
05DACActual negotiated output
AUTOMATIC / BEST

Keep native playback where the full path supports it; otherwise perform only the conversion needed for the highest-quality valid route.

NATIVE / BIT-PERFECT

No resampling or downmixing. If the whole path cannot carry the source unchanged, Core says so and refuses the path.

COMPATIBILITY

Allow the transformations needed to make playback work while preserving the original master and exposing the conversion chain.

TECHNICAL SPECIFICATIONS

Audio-first. Preservation-first.

Beta 1 is deliberately broad about the audio it will accept, but conservative about what it claims to have verified.

TREV PRODUCTION HARDWARE TARGET

Built with headroom rather than a tiny audio budget.

The production hardware platform is a target under validation, separate from what Beta 1 software has already proved.

16PCM output channels
8 × stereo I²S TX lanes
8PCM capture channels
4 × stereo I²S RX lanes
2×25GbE SFP28
production network target
DSDNative clock/data paths
8 DSD TX lines target

Extreme-rate target: PCM 1536 kHz and DSD1024 remain architectural targets pending physical DAC/interface validation. Beta 1 does not present them as hardware-certified capability.

CHOOSE HOW FAR YOU GO

One Control family. Three ways to use it.

STANDALONE

Your Mac. Your music.

A local persistent library and stereo playback without needing a Core appliance or Sooloos system.

SOOLOOS

Meridian, without leaving it behind.

Bring an existing Meridian/Sooloos library and zones into the modern Control experience while keeping the system useful in its own right.

BRING THE COLLECTION WITH YOU

Built around real libraries, not a blank streaming account.

Provider availability and playback capabilities vary by service, account, platform and endpoint. Beta 1 reports capability truth rather than pretending an unavailable integration is working.

BETA 1 · SEPTEMBER 2026

Built to be used. Still being finished.

Beta 1 marks the first Brimstone release baseline: the architecture is locked, Core and Control are being polished as a product, and remaining work is focused on defects, validation, packaging and production hardware rather than endless feature churn.
