7.2. Software Loopback Solution (Windows)
The Software Loopback Solution (SLS) is an extension of the Loopback function described
above. It gives you a great deal of flexibility in recording and playing back audio, within an
easy-to-understand user interface.
SLS is currently available only for Windows PCs with the MiniFuse 1 and 2. A macOS version is
forthcoming, as is a version that works with the MiniFuse 4.
Even though your MiniFuse has only one or two physical inputs and two physical outputs,
to your recording and playback software it appears as an interface with eight inputs and
eight outputs! These four stereo pairs allow you to route audio to and from multiple apps, in
addition to listening to your audio from the MiniFuse.
Here's how it works.
All of the images shown here will be from a MiniFuse 2, but the exact same features apply to the
MiniFuse 1.
7.2.1. Physical vs. Virtual Inputs and Outputs
In addition to the physical inputs and outputs on your MiniFuse, there are three sets of
stereo virtual inputs and virtual outputs. They don't exist in physical form... but your software
doesn't know that!
With these virtual channels, you can get your various apps to share audio smoothly. You can
easily create workflows that are great for podcasts, live streaming, and more. It's all done
in SLS inside your computer, so your MiniFuse just has to deal with what's actually going in
and out of the box.
Imagine a typical livestreaming setup, where you may be:
•
recording yourself and a guest on two mics (panned left and right to put some
space between you), while also
•
running OBS Streamlabs to send the video and audio out to the world, while also
•
talking with an interviewee via Zoom or Skype, while also
•
playing back a music bed, while also
•
recording music to and from a DAW or other app
...and have it all happen live, rather than mixing it all together later in post-production. Thanks
to SLS, you can do all these things at once, sending different mixes to video, chat, and your
DAW.
