I built Oreja after getting tired of reaching for Apple Music every time a ChatGPT voice reply started. It watches the selected app's output level locally, pauses Music while the reply is active, then brings it back after the quiet interval. There is also a lower-volume mode.
The whole thing is intentionally small. No OpenAI API, account, recording, transcript, analytics, or network service. The repository is open source, and the audio path feeds transient levels into a deterministic coordinator.
