Recadio is a simple and elegant tool that completely solves a very annoying problem on macOS: audio devices can switch automatically and unexpectedly. If you have to manually reselect your microphone or speakers every time after connecting headphones, this app was built for that purpose.

Whenever you connect Bluetooth headphones to your Mac, the system usually switches both audio output and input (microphone) to the headphones automatically. This leads to two main problems:

• Degraded sound quality: When the system uses the headset’s built-in microphone, the Bluetooth codec may switch to headset call mode, resulting in noticeably lower audio quality.
• Messy audio settings: You may have to open System Settings every time to reselect your preferred microphone, such as an external USB microphone, while still wanting the headphones to be used only for sound output.

Recadio works on a “set it once, and forget it” basis. You simply assign a priority order to your audio devices, and Recadio will automatically choose the highest-priority device that is currently connected. That way, you won’t run into audio devices abruptly switching during important video calls.

Features

• Automatic selection by priority: Set a priority order for different audio devices, and Recadio switches automatically based on which devices are connected.
• Device locking: Temporarily “lock” the device you want to use at the moment, so the system won’t switch even when a new audio device is connected.
• Quick access: Switch devices with one click from the menu bar icon, or use keyboard shortcuts, without having to keep opening System Settings.
• Simple and reliable: The app focuses on the core audio device switching function and handles it in a simple and stable way.

Recadio is perfect for users who frequently use external audio devices such as microphones, headphones, and headsets. It’s especially useful for those who regularly join video conferences, record podcasts, work with audio, or simply want to listen to music without microphone switching hurting the sound quality.
