Hmmm...perhaps you guessed the primary reason for selecting a relatively expensive processor.

The Teensy 3.6 has a floating point unit and can do FIR filtering and more at that sample rate with the audio library.
So the IIR filters used here, which are at least an order of magnitude more CPU efficient, and should not be an issue for the Teensy 3.6.
One very interesting feature that opens up with this combination of CPU and library is the USB audio device emulation that would allow a computer to connect via USB for digital modes without a digital interface.
Plus the real possibility of on-board decoding and encoding of digital modes as well as built-in SDR.
