dsh-bgm turns system audio into rhythm-game feedback for the official DSH Web UI. It captures the default output device independently of the music player, maps bass/onset to Deep Diving, maps mid/treble changes to the latest reasoning or tool row, and keeps final-answer text readable and still.

The wide-screen layout gains two optional 12-bar RGB spectrum banks in the empty gutters; the banks move as a continuous travelling wave that flows from the outer edges toward the conversation, with a beat crest merging inward on every downbeat. Stable activity text forms a continuous BPM-locked wave surface; predicted notes fly toward a judgement line and build Score, Accuracy and Combo. Score and PERFECT milestones trigger card-game rewards: a light pill card from 1,000–5,000 points, then a full card that tumbles in from the upper-left with a 3D flip, lands on the right and pops like the rank reveal. A completed answer can end with a transparent 3.2-second score roll, rank burst, note rain and staggered statistics reveal.

Install into the official DSH Web profile

Supports legacy DSH 0.1.0-rc.8 and 0.1.1-rc.1/rc.2, and is adapted for the latest 0.1.5-rc.2. The release tarball contains a universal macOS helper and a self-contained Windows x64 helper, so the install does not need a source build:

dsh plugin --profile web add https://github.com/skymecode/dsh-bgm/releases/latest/download/dsh-bgm.tgz
dsh web

Pinned release:

dsh plugin --profile web add https://github.com/skymecode/dsh-bgm/releases/download/v0.1.3/dsh-bgm.tgz

Remove it with:

dsh plugin --profile web remove dsh-bgm

Supported hosts:

• macOS 14.2 or later, Apple Silicon and Intel. The first run requests system-audio recording permission.
• Windows 10/11 x64. No separate .NET installation is required.
• Linux currently has no loopback helper and reports an unsupported state without restart loops.

Privacy and performance

• Raw PCM stays in the local native helper's memory and is never recorded, persisted or uploaded.
• The browser receives only RMS, bass, mid, treble, onset and timestamps.
• Streaming React text is never rebuilt into per-glyph mirrors.
• The 24 atmosphere bars are persistent nodes updated only through GPU-composited transforms and opacity; the travelling wave adds no per-bar filters or layout reads.
• Reduced-motion preferences disable the primary animations.

Development

git clone https://github.com/skymecode/dsh-bgm.git
cd dsh-bgm
pnpm install
pnpm run typecheck
pnpm run build

CI builds Host and Client bundles, produces universal macOS and Windows x64 native helpers, inspects the packed artifact, and mounts it into clean official DSH 0.1.0-rc.8, 0.1.1-rc.2, and 0.1.5-rc.2 Web profiles. A v* tag assembles dsh-bgm.tgz, writes SHA256SUMS.txt, and publishes both through GitHub Releases.
