AudioSDR

A single Teensy Audio Library class object for a complete SDR (software-defined-radio) demodulator/processor.

  • Creates a dual-conversion receiver with an IF at approx. 7kHz
  • Contains demodulators for CW/SSB/AM/SAM and a WSPR mode
  • Contains an impulse noise blanker, AGC, ALS (adaptive-least-squares) automatic notch/peak filters
  • Contains demod mode dependent IF and audio band-pass filters
  • Uses float32 processing throughout.
  • Uses the I2S input and output on the Teensy Audio Board.
