Multiplicity Audio

Multiplicity has the ability to send audio from one or more computers over a network to another computer. Any audio output from the Multiplicity 'sender' is sent over the network to a Multiplicity 'receiver'.

A Multiplicity computer can receive audio from many other Multiplicity computers, however, a sender can only send audio to one other Multiplicity computer.

Example:

The designation of Primary or Secondary is not considered for audio sending or receiving. A Primary or Secondary can be either an audio sender or receiver.

Sending and receiving audio is not available with Windows XP.

Setting up the Multiplicity audio receiver

Alternatively, you can get to the audio settings via the Multiplicity Audio system tray icon.

Check the 'Enable audio sharing' option
Select 'Receive audio from other computers'
Select 'Change receiver passcode' to set one of your choice (at least six characters and does not need to match your Multiplicity connection passcode).

Setting up the Multiplicity audio sender

Open the control panel on the Multiplicity computer you want to send audio from and check the 'Enable audio sharing' option and select 'Send audio to another computer' option.

In the 'Send audio to' field, enter the computer name or the IP address of the receiver. Enter the passcode you set for your receiving computer.

At this point, any audio produced by the sending computer will be heard from the receiving computer's playback device. Please see Troubleshooting section in this document should there be complications.

Advanced Audio Settings

Only receive audio from computers on the same subnet as this computer

This will restrict audio to be received only from computers on the same IP subnet as the receiving computer.

Communicate on port

Enables the port to be specified that audio is sent and received on. It must be the same value for each sender and receiver.

Use lossless compression when sending audio (Will increase delay slightly but reduce bandwidth)

This enables audio compression and can be used to save network bandwidth.

Send audio when the receiver is online (You can toggle this via Ctrl + F12 or the system tray menu)

When the sender sees that the receiver is online, it will automatically send audio to it.

Enable Ctrl+F12 hotkey to toggle sending audio

Use this key combination on the audio sender to turn on and off sending audio to the receiver.

Disable Windows 7/8 jack detection

Windows 7 (or greater) will sometimes not send audio when it detects that there are no playback devices attached (speakers, headphones, etc). Enable this option to bypass that.

Buffering Control

Increasing this option will improve audio quality when network conditions are poor but also increases latency (delay) slightly.

System tray settings (upon right click)

Send audio when receiver is online

When the intended receiver is online, audio is automatically sent to it.

Allow this machine to be unmuted

With this option enabled, audio from the sender will be heard on both the sender PC and the receiver PC.

Configure Multiplicity Audio

This will open the Audio configuration options.
