Adds platformConfig struct with platform-specific ffmpeg input flags for macOS (avfoundation), Linux (pulse), and Windows (dshow). Implements ffmpeg subprocess management: start, stop, pause, resume, cancel with appropriate error handling. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implements nextAttemptNumber() that scans for existing attempt-N.mp3 files and auto-increments. Adds --force flag to restart numbering from 1. Command parses QID, validates ffmpeg, and will launch TUI (runRecorderTUI added in next task). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implements recorderModel with bubbletea for audio recording interface. Features: real-time timer (MM:SS), pause/resume (Unix), stop/cancel with file cleanup, platform-aware controls (Windows pause disabled), and styled status display with lipgloss. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds recordCmd to the commands slice in initCommands() after editCmd. Command now appears in help with proper description and --force flag. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds real-time frequency spectrum display during recording using: - Radix-2 Cooley-Tukey FFT (no external deps) - ffmpeg asplit filter: MP3 to file + raw PCM to stdout pipe - Logarithmic band grouping over voice range (80Hz-8kHz) - Colored Unicode block characters with green→red gradient - PCM reader as bubbletea async command for smooth updates Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Removes rainbow colors, uses plain Unicode block characters - Dynamically adjusts number of frequency bands to terminal width via tea.WindowSizeMsg (each band = 2 chars, ~40 bands on 80-col terminal, ~60 on 120-col, etc.) - Logarithmic band grouping still covers voice range (80Hz–8kHz) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Nvm, this is a feature I'm developing on my own fork. I opened this up by accident. I basically want to add functionality to record myself while I solve the leetcode problems, using LeetGo directly. And I even want LeetGo to talk to LLM providers to transcribe my audio recording & generate an analysis summary using any LeetCode problem's description, my solution & my audio transcription. But I'm still prototyping all of this, so I'll create a proper PR after I've built this & used it myself for a while. |
