Audia & audia-tap

Highlights

• Built a production macOS menu-bar app for real-time per-app audio routing, alongside audia-tap, an OSS CLI for piping raw PCM audio directly into local AI models (Whisper, MLX).
• Engineered a driver-free Core Audio HAL capture pipeline at <10ms end-to-end latency via PID-level stream hookup and a custom lock-free SPSC ring buffer.
• Cut streaming CPU overhead 30–40% using SIMD-accelerated DSP (Apple Accelerate) for real-time EQ across concurrent high-fidelity pipelines.
• Automated the end-to-end CI/CD release pipeline with GitHub Actions: signed DMG releases, Homebrew updates, and Sparkle OTA auto-updates.
