audia-tap is a driverless, open-source Swift CLI that extracts raw audio from any specific macOS app. Bypassing the system mixer entirely, it uses a native HAL tap to capture audio by PID or app name and pipes raw PCM/WAV data straight to stdout. No BlackHole or Loopback required. Perfect for feeding isolated app audio directly into local AI models like Whisper or FFmpeg.

Hi Product Hunt! 👋 We are currently building a native macOS audio app. While building the core engine, we realized there was a huge need for a native, driverless way to extract audio from specific apps for AI transcription pipelines. So, we're open-sourcing our foundational extraction engine: audia-tap. It's a standalone Swift CLI that uses a native Hardware Abstraction Layer (HAL) tap to hook into any running app's PID and pipe raw 16-bit PCM audio straight to stdout. Driverless: No need to install BlackHole, Soundflower, or Loopback. App-Specific: Captures exactly what you want by app name or PID without system notification bleeds. UNIX Philosophy: Pipes directly into Whisper, FFmpeg, Parakeet, or any downstream LLM. We’d love for you to clone it, pipe some audio into your local models, and let us know what you think of this implementation!
