Best Multiple Audio Output Software for Windows
Compare the best Windows software for playing audio through multiple output devices simultaneously. VoiceMeeter, Soundoper, and more.
The Short Answer
The best multiple audio output software depends on your needs. For simple "play audio through all devices" functionality, Soundoper is purpose-built for the task. For advanced virtual audio routing, VoiceMeeter offers more power. For free and lightweight, VB-Audio Virtual Cable provides a building block.
Why You Need Multiple Output Software
Windows sends audio to one default output device at a time. If you want the same audio on headphones and speakers, or on two Bluetooth speakers, you need software that duplicates your audio stream to multiple physical outputs.

VoiceMeeter
Best for: Advanced audio routing and mixing
