Audio sharingOne source,a room of speakers.
Whatever your computer is playing, from any app, can play on another computer or a phone. Pick several devices to play together and give each one its channel.
Getting started
- 1
Connect
Open Whisper on the computer and on the devices that will play, and connect them.
- 2
Choose devices
In the computer’s device tools, choose audio sharing, select one or more playback devices, and set each one’s channel.
- 3
Play
Sound from the computer now plays on all of them. Adjust or stop at any time.
More than one speaker.
Everything the computer plays
It shares the system’s output, so music, video, and calls all come through without setting up each app.
Several devices at once
When devices play together, Whisper estimates the clock offset between them to keep them aligned, and shows how well they are in sync.
Left and right channels
Set each device to stereo, left, right, or mono. Two phones can become a makeshift stereo pair.
A phone as a speaker
An Android phone can be a playback device, bringing the computer’s sound to wherever you are.
Volume per device
Each playback device has its own gain for shared audio. It only affects that device, not the computer’s volume.
Local network only
Audio travels directly between devices on your network, never through a server.

Questions
Why does the Mac ask for Screen Recording?
macOS puts capturing system audio under the Screen Recording permission. When sharing audio, Whisper takes only the sound and does not record what is on screen.
Is there a delay? Can I watch video with it?
Audio goes through the network and a buffer, so it plays a little later than on the computer itself, depending on your Wi-Fi. Music and podcasts are fine; where sound must match the picture, as in video or games, you may notice it lagging.
Can I share my phone’s audio to the computer?
Not at the moment. Android only plays; sharing starts from a computer.
