First of all i wanted to say i'm new to Teensy.
Guys please tell me whether below requirements can be successfully achieved by Teensy 3.2 (Also guys keep remember i'm not going to use audio shield because my requirement is to create a small device)
1) I thought to use - " Adafruit AGC Electret Microphone Amplifier - MAX9814 ". It needs to connect for ADC pin and sample at lower sampling rate (Below 44 KHz, Since my ADC picks signals only upto 3KHz maximum. I'm using a technique of PLL to trigger the Teensey 3.2 and when the signal present at that level it should begin to sample. So no point to use higher sampling rate). So is that possible to change the pre-scalar values of ADC at teensy? If so please post the links for the libraries and share threads.
2) I needed to implement a DSP filter inside the MCU. so simply i want to make IIR bandpass filer inside the chip. Is their any libraries for teensy 3.2? or else please provide me the links and libraries to refer on. I already found constant values from MATLAB
3) Next step i want to store all the captured samples on a SD card. (with .wav format) Is that possible ? and what are the libraries which capable of doing that?
4) Final stage again access SD card and convert .wav files into FFT and analyze frequncy bins. What are the libraries and please share links
Guys please tell me whether Teensy 3.2 is capable of doing all this steps. And please share all the links and libraries on each particular steps.
