    I would love to use the library for that exact reason. I guess I just had a way in my head I was going to do this using just the Teensy, but now with the library that has shifted.

    The general...

    Is there a simple way to read line in through the audio boards through the adc and put the values in a buffer? Or do you have to use queue to create the audio buffer?

    I am looking to do this on a T4.0.

    Do I still jump to pin32 (pad)?
    Do I need to remove the 10K resistor?

    Almost positive the first question is a yes, but not sure about the second.
  4. Yes I almost have the audio board in so when I...

    Yes I almost have the audio board in so when I get that I will likely try both situations. I currently have a pretty good baseline, but will have to mess around with the bandpass filter,sampling...

    Thanks for the information. I am definitely learning about all of this as I go. Like you say this is all fun, but at the same time I would like to try and get this to work with the least amount of...

    I struggle to see how sampling more often will not get me better accuracy. If I sample a 500hz sine wave through 2 different microphones and sample it at 1000hz and then cross correlate them to find...

    How would I create a buffer to do this? It is possible that I could be sampling for minutes before a read which at 400KSPS that would be an insanely larger buffer. Is there a way to get around...

    After lots of research, I've come to the same conclusion you both have for using the ADC and cross correlating each signal. I took a relatively extensive signal processing engineering class 6 years...

    Pedvide ADC library with 4 microphones

    Hello,

    I am using pedvide's ADC library for my project where I am reading in a buffer array from each microphone when one of them receives a signal that is bigger than the background noise...

    Update: I used analogReadContinuous() for 2 channels and got rid of the interrupts. I now have about 880KSPS. Is there anything else I can do to the code to help?


    #include <ADC.h>

  11. Teensy 4 How to increase speed of my sample readings using both ADCs and 4 Mic inputs

    I am working on a project trying to sample 4 analog mics as fast as possible using a Teensy 4.

    I was wondering if there was anyway that I could increase the samples/second I am getting. I am...

    Ah too bad, but thanks for the information it will be very helpful. All of this makes sense. The one thing I still would like to figure out is how to start sampling. If I used all 4 microphones,...

    Hi Juan,

    Thanks for the response. Is there anyway you would be able to share the code you wrote for that? It is seemingly very close to what I would be doing and I am also a bad coder.

    If...
  14. Point Triangulation from Sound with high accuracy

    I am in the middle of a project where I am trying to triangulate the source of a noise. I am going to use a teensy 4 for this project. I do not care about audio quality, I just need quick response...
