About this app

CastSound — the wireless speaker, microphone and webcam app that connects your Android phone to your Mac or Linux PC. Stream audio and camera between your phone and computer with ultra-low latency, no cable, no Bluetooth pairing.

WIRELESS SPEAKER FOR MAC & LINUX
Stream any audio from your Mac or Linux PC to your Android phone over WiFi: music, movies, games, browser tabs, system sounds — if your computer plays it, your phone plays it. Walk around your home, garden or office while your desktop audio follows you.

WIRELESS MICROPHONE
Use your Android phone as a crystal-clear microphone for your Mac or Linux machine — perfect for video calls, meetings, Discord and gaming. Your voice streams to your computer in real time with echo cancellation.

ANDROID AS WEBCAM — NEW
Turn your Android camera into a high-quality wireless webcam for your Mac or Linux PC. Works with Zoom, Google Meet, Teams, OBS and any app that sees a camera. One tap starts video right alongside your audio.

Why CastSound?

• Speaker, microphone and webcam work at the same time on one connection
• Automatic discovery of your Mac or Linux PC on your WiFi network
• Background playback: use other apps while listening to your computer

Everyday uses:
