The Analyzer Control & Routing window allows you to control SpectraFoo’s global analyzer parameters and
how signal is globally routed through the analysis system. SpectraFoo’s analysis routing model has two layers
for maximum flexibility:
• By selecting an audio device from the Audio I/O menu’s Configure Hardware selection you choose
the audio hardware that SpectraFoo uses to acquire the audio streams to analyze. SpectraFoo uses the
Analyzer Control & Routing matrix to allocate each of the audio device's signals to any of SpectraFoo's
analyzer channels.
• Each of the SpectraFoo instruments has an internal routing control that allows you to select any of the
analyzer channels to feed the instrument. This process is illustrated below:

Analyzer Channels
In SpectraFoo there is a difference between analyzer channels and analysis instruments. In SpectraFoo you can
have many different types of instruments monitoring the same channel as well as many different versions of
the same instrument monitoring the same channel. You can also monitor multiple channels simultaneously.
With the analyzer pop-up in the control and routing window you can set the number of channels you want to
be able to monitor simultaneously. If you set the number of Analyzer Channels to 2 you will be able to actively
monitor two channels from your input hardware at one time. However, the number of analyzer channels
within SpectraFoo and the number of hardware channels are independent. The number of hardware channels
