How do I route audio playing on my computer back into EMU?

There are two main methods for routing audio between 3rd party applications and EMU that are running on the same computer. Routing audio can be used for things like, sampling audio being played back from DAW (Digital Audio Workstation) or audio from a video stream.

Virtual Routing

Various virtual 3rd party audio-routing applications exist for macOS and Windows. Some the most popular options are listed below:

  • iShowU Audio Capture (macOS only)
  • Soundflower (macOS only)
  • Black Hole (macOS only)
  • Rogue Amoeba Loopback (macOS only)
  • Jack (Windows and macOS)
  • VoiceMeeter (Windows)

Follow the 3rd party instructions for installation. Once installed, these will show up as audio drivers in EMU’s Preferences>Audio dropdown preferences (as well as the preferences of other audio-enabled applications).

Analog Routing

If you are using a physical sound card or and have a spare output on your audio interface, connect a cable (or set of cables) from there to an input on the same interface.

Configure the audio interface preferences so that one Program is outputting via the analog out, and the other is set to receive the analog input. This option is by far the simplest.

Can I send multiple audio inputs into EMU at once?

EMU supports a maximum of one stereo input at a time which is averaged before each band and sampled at 48KHz. To input multiple inputs to virtual mixer software capable of mixing all audio sources to a single stereo feed or using a physical mixer to combine all audio sources to a single stereo feed to be received by EMU.

Can I define different EQ settings per Program? 

You can set different Sound Tracker settings on a Per Program basis but not the Global EQ settings.
