Project: /home/user/Projects/protech-studio Created: 2026-04-15
Built ProTech Digital Studio v2.0 (2026-04-15 05:34)¶
What: Full recording studio web app built on the existing React/Vite/Tailwind shell.
Why: User requested a professional recording studio with audio/video recording, live streaming, AI integration, and a beautiful UI — built on top of the existing protech-studio project.
How: - src/hooks/useMediaRecorder.js — MediaRecorder API hook: getUserMedia, getDisplayMedia, start/stop/pause, file naming (type_YYYY-MM-DD_HH-MM-SS.webm), download, state management - src/hooks/useAudioEffects.js — Web Audio API effects chain: 3-band EQ (bass/mid/treble), dynamics compressor, algorithmic reverb (ConvolverNode with generated impulse), delay with feedback, input/output gain, live parameter updates - src/components/WaveformVisualizer.jsx — Canvas-based real-time audio visualization (bars + waveform modes) via AnalyserNode + requestAnimationFrame - src/components/RecordingStudio.jsx — Main studio UI: mode selector (A+V/Audio/Video/Screen), device selector, quality presets (Low 360p → Ultra 1440p 60fps), live camera preview with CSS video filters (8 presets: Normal/Vintage/Cyberpunk/B&W/Warm/Cold/Neon/Matrix), recording controls with timer - src/components/EffectsRack.jsx — Full effects panel with sliders for all audio params + video filter preset buttons - src/components/StreamingPanel.jsx — Live stream preview, RTMP config (Twitch/YouTube/Custom), simulated stream stats, pre-recorded playback mode, Go Live controls - src/components/MediaLibrary.jsx — Recordings grid with thumbnail preview, type/size/duration info, play modal, download, delete - src/components/AIPanel.jsx — Web Speech API live transcription + Gemini 2.0 Flash chat (API key stored in localStorage), quick actions (generate title/description/show notes/key points), transcript auto-injected as context - src/App.jsx — Main layout: sticky header with tab nav + theme/model switcher, 5 tabs (Studio/Effects/Stream/Library/AI), recording badge, status bar - src/index.css — Full theme-aware CSS: TRON (cyan glow, grid bg), MATRIX (green mono), STANDARD (clean light) — all buttons, inputs, sliders, scrollbars, animations use CSS variables
Files created/modified: - src/App.jsx (modified) - src/index.css (modified) - src/hooks/useMediaRecorder.js (new) - src/hooks/useAudioEffects.js (new) - src/components/WaveformVisualizer.jsx (new) - src/components/RecordingStudio.jsx (new) - src/components/EffectsRack.jsx (new) - src/components/StreamingPanel.jsx (new) - src/components/MediaLibrary.jsx (new) - src/components/AIPanel.jsx (new) - Backups: App.jsx.bak, index.css.bak
Dependencies: Zero new npm packages — uses only existing React 19, Lucide React, Tailwind CSS 4. All media APIs are browser-native (MediaRecorder, Web Audio API, WebSpeech API, WebRTC).
Phase J — AIPanel Gemini preset + CheerpX Terminal + CHACHA Phase J entry (2026-04-16 01:25)¶
What: Added Gemini as a named provider preset in AIPanel.jsx; CheerpX terminal tab wired into App.jsx; CHACHA.md Phase J entry appended with full session summary and twin directives. Why: User said 'we need gemini' — Gemini was missing from provider list. CHACHA needed updating with today's completed work and warning to Gemini about shell commands. How: Added gemini preset to PRESETS object in AIPanel.jsx (generativelanguage.googleapis.com/v1beta/openai — OpenAI-compatible). CHACHA appended using unique anchor line at end of file. Build: clean 262 kB. Files: src/components/AIPanel.jsx (gemini preset added), ~/claude/CHACHA.md (Phase J entry appended)
