- Save every completed generation to SQLite (generation_store.py) with
WAV and waveform peaks written to data/generations/<id>/
- Deferred DB write until success — cancelled/errored generations never
touch the DB and never appear in the library
- Fixed cancel+regenerate IndexError: _reset_scheduler_caches() now
directly zeros scheduler._step_index and running state in addition to
clearing VibePod cache dicts; same explicit resets added in the fresh
path of prepare_noise_scheduler as belt-and-suspenders
- Added /library page with GenerationCard, WaveformPreview, waveform
fetch, play/pause, download, delete, pagination, empty + error states
- Added generation API routes (list, single, audio stream, waveform,
delete) proxying to Python server
- Added Library nav link to Header with active state
- Persist script/speaker/CFG to localStorage so generate page state
survives navigation
- Updated build plan: Phase 0+1 ticked off, better-sqlite3 moved to
Phase 2, architectural note on Python owning all persistence
- Extract WAV assembly (buildWav, mergeFloat32Arrays, decodeFloat32Chunk,
SAMPLE_RATE) into web/lib/audio/wav.ts so it can be reused by the
Studio playback engine and library waveform previews
- Add server/waveform.py with compute_peaks() / write_peaks() — reads
any WAV, mixes to mono, returns min/max peak arrays matching the
WaveformPeaks TypeScript type
- Add server/ids.py with prefixed URL-safe ID helpers (gen_id, proj_id,
asset_id, etc.) using stdlib secrets — no new dependency
- Add docs/studio-build-plan.md — full execution spec covering stack
decisions, data models, API contract, component hierarchy, phase
breakdown and acceptance criteria
- Ignore data/ directory (generated audio, waveforms, SQLite DB)
Keep CPU async decode enabled without CFG parallelism, expand CPU buffering defaults for smooth playback, prevent CPU startup from mutating the lockfile during thread autodetection, and document runtime tuning variables in the example environment file.
* Improve CPU Inference Stability: Implement Adaptive Buffering and Chunk Accumulation
This change addresses audio stuttering issues when running on CPU-only hardware by:
- Implementing server-side audio chunk accumulation to reduce SSE overhead.
- Introducing device-aware default configurations for buffering and inference steps.
- Exposing key performance parameters as environment variables.
- Enabling the frontend to adaptively adjust its buffering thresholds based on the server's configuration.
Changes:
- Modified `server/vibevoice_server.py` to support accumulation and provide config via `/health`.
- Updated `web/hooks/useStreamingGeneration.ts` to accept configurable buffering parameters.
- Updated `web/app/page.tsx` to fetch and apply server-side configuration.
Verified on CPU mode in the development environment.

* Improve CPU Inference Stability: Adaptive Buffering UI & Logic
This change enhances the initial CPU stability fix by:
- Exposing adaptive buffering settings (Pre-buffer, Re-buffer Threshold, Resume Threshold) in a new "Advanced Buffering" UI section.
- Managing buffering settings in the application state to allow for manual overrides.
- Implementing robust re-initialization of buffering and inference defaults whenever the server's device (CPU/CUDA) changes.
- Including the active device in the server's config object for reliable client-side detection.
Verified with frontend screenshots and full build. Responds to PR feedback regarding actioning the adaptive logic.

* Refine adaptive buffering: env helpers, threshold validation, a11y fixes
- Extract _env_int/_env_float helpers in server to validate env-var config
with graceful fallback instead of bare int/float casts
- Fix inference_steps falsy-check (0 is valid) to use explicit None guard
- Enforce rebufferThresholdSecs < resumeThresholdSecs in both the hook
(with console.warn + clamp) and the GenerationControls UI (sliders block
invalid states by auto-bumping or ignoring the drag)
- Add type="button", aria-expanded, aria-controls, htmlFor, and input id
attributes to GenerationControls for accessibility
- Add .vscode/settings.json to .gitignore; sort package.json scripts

- Replaced multiple named event handler functions with inline state setters.
- Used an AbortController to cleanly remove all event listeners with a single `controller.abort()` call in the cleanup hook.
- This improves maintainability and readability by reducing verbosity without changing functionality.
- Formatted inline callbacks across multiple lines for better readability as requested.

Extract the duplicated offline response payload and common headers into
constants to improve maintainability and readability.
- Define OFFLINE_RESPONSE for { status: "offline" }
- Define COMMON_OPTIONS for { headers: { "Cache-Control": "no-store" } }
- Use these constants across all response paths in the route.
