FlexASIO: Audio Driver for Multiple App Routing

FlexASIO routes audio signals to multiple applications at once, allowing digital audio workstation software and effects plugins to access your audio interface simultaneously.

What is FlexASIO?

FlexASIO is an audio driver designed for digital audio workstations and effects plugins. It enables multiple audio applications to access an audio interface at the same time, allowing seamless routing of audio signals between software.

Traditional ASIO drivers only allow one program at a time to access an audio interface. FlexASIO gets around this limitation by intercepting the audio streams and routing them to multiple destinations. This eliminates the need to constantly switch between applications when recording and processing audio.

Key features of FlexASIO include:

  • Simultaneous routing of audio interfaces to multiple software applications
  • Support for all major DAWs and plugin formats
  • Low latency monitoring
  • Customizable input and output matrix routing
  • ASIO driver compatibility for older software

FlexASIO makes workflow much faster for tasks like recording into a DAW while monitoring effects from a plugin. It's useful for audio engineers, musicians, podcasters, and anyone needing advanced audio routing capabilities across multiple apps.
