digimata/quill

This system is a cross-platform audio recording utility, now named Quill, that captures simultaneous microphone and system audio tracks on both macOS and Windows. It provides robust, crash-safe recording with automatic recovery from device route changes on macOS and process-tree loopback capture with checkpointing on Windows. The project includes native build scripts for both operating systems and has recently removed its legacy local two-track meeting recorder in favor of these more resilient, platform-specific implementations.

New shell scripts have been added to streamline the macOS development workflow. The \build-macos\ script now allows users to compile the project using Swift in release mode from the repository root. Additionally, the \install-macos\ script enables direct installation of the resulting binary to \/usr/local/bin\ (or a custom directory specified by \QUILL\_INSTALL\_DIR\), handling the necessary directory creation and file permissions automatically.

The new Windows directory adds a console capture probe that records two independent WAV tracks (system audio and microphone) using WASAPI. System audio is captured via a process-tree loopback (targeting a specific app and its children) or a fallback endpoint loopback, while the microphone is captured from the default input device. The probe enumerates candidate processes by inspecting audio render sessions and resolves capture targets to their top-level application boundary. Audio is written to 16-bit mono WAV files with a crash-tolerant checkpointing mechanism that persists headers every ten seconds to ensure data integrity on hard termination. The probe outputs session metadata (meta.json) and reports specific diagnoses such as silent tracks or target process exit.

The local two-track meeting recording capability has been removed. The \MicRecorder\, \SystemAudioRecorder\, and \RecordingSession\ classes, which previously enabled simultaneous capture of microphone and system audio into separate tracks, have been deleted from the codebase.

The macOS recorder now detects and recovers from audio capture interruptions caused by system audio route changes (such as connecting or disconnecting AirPods or switching default devices). A new health-monitoring system watches both the microphone and system-audio tracks; if a track stalls, it automatically restarts capture into a new numbered segment (e.g., mic-002.caf) while preserving previously recorded data. The menu bar indicates recovery status (orange icon), and the final session metadata reports whether each track is complete, recovered, or incomplete.

The Windows build now uses a dedicated Cargo workspace with \Cargo.toml\ and \Cargo.lock\, pinning dependencies such as \clap\ to version 4.6.5, \chrono\ to 0.4.45, and \windows\/\windows-core\ to 0.62. On macOS, the project has been renamed from 'lyrebird' to 'quill' and updated to target macOS 15, introducing a new \FluidAudio\ dependency (version 0.15.5 resolved, 0.7.0 minimum) and adding a \QuillTests\ test target.

• Inconsistent constructor naming convention. LoopbackRecorder uses 'new' while MicRecorder also uses 'new', but the naming pattern is not uniform across all recorders if more are added. More importantly, 'new' is a Rust keyword convention, but in a public API surface review, it's worth noting if other types use 'create' or 'from'. However, looking at WavWriter, it uses 'create'. This is a minor inconsistency in factory method naming.
• Inconsistent factory method naming. 'create' is used for the basic case, while 'with_patch_interval' is used for a variant. This is a common pattern (Builder/With), but 'create' vs 'with_' is slightly inconsistent. Usually, it's either 'new'/'new_with_' or 'create'/'create_with_'.
