I am wondering if there is a way to get a high resolution FFT with the teensy. I am trying to find tones that are only 15 or so hz apart.
Not sure what sample rate I will being using because I can't seem to find sampling rate information in the docs for AudioInputAnalog or AudioInputUSB.
(Been General for almost a year and I still have not done any HF.)
I have silly question. Is it be better to use the Arduino IDE with the changes to it or to just use VS Code with PlatformIO that I use for all my other microcontrollers (Arduino,ESP32)?
Can you explain this in more detail? How does the audio output affect the clock generator?to run a SI5351 off the audio output of my computer.
