#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SerialFlash.h>
#include "Arduino.h"...

Dear all,

I successfully created the low frequency sawtooth wave, which is 0.5 Hz, the results is really good, however, I tried to record it by the recorder example, I found out the AC coupling in...

This is the full program I wrote and I cant hear anything. Look like there is somthing wrong with playQueue. However, I tried directly sent to i2s1 from SDWav and heard my song playing.

Hi everyone, I want to used AudioPlayQueue and play the sound from AudioRecordQueue. When looking to the .cpp file, I found the different userblock queue size, I have an question to ask that will...

Hi Paul, thank you for all your work for this example and that was an awesome post. You are my idol.

Based on the result above, the target of creating low freq signal is possible.

I think I...

Dear all, I have a project which based on Teensy 3.2 and the Audio Board. Mainly this project is used to create a waveform analogue signal that has 1 Hz frequency. The waveform can be square or...
