    How to use Teensy libraries to do signal processing

    "speed can be any from the ADC_SAMPLING_SPEED class enum: VERY_LOW_SPEED, LOW_SPEED, MED_SPEED, HIGH_SPEED or VERY_HIGH_SPEED. ADC_SAMPLING_SPEED::VERY_LOW_SPEED is the lowest possible sampling speed (+24 ADCK). (ADCK is the ADC clock speed, see below). ADC_SAMPLING_SPEED::LOW_SPEED adds +16...

    How to use Teensy libraries to do signal processing

    "Except for the noise reduction involving unspecified algorithms, you can do all this pretty easily with the audio library." Would you happen to know any open source algorithms fit for teensy that can do the job?

    How to use Teensy libraries to do signal processing

    thanks for the reply! would you happen to know how the StateVariableFilter works? I'm not too sure why it's input says white noise. and where does it gets the input? Would it be safe to say that I could edit the input to make it filter our chosen input signal? /* Example of filtering audio...

    How to use Teensy libraries to do signal processing

    For our project our goal is to acquire body sounds from an acoustic stethoscope and do digital 1) filtering 2) noise reduction (static + heart sounds), and 3) amplifying of signals. The frequencies we're trying to detect ranges from 20 Hz to 2kHz. Here is a block diagram of our plan so far ADC...
