AudioTools: I2SCodecStream

You can use the I2SCodecStream like the I2SStream but it provides some additional functionality, like setting the volume via the codec. In the constructor you need to provide an audio board object.

#include "AudioTools.h"
#include "AudioLibs/I2SCodecStream.h"

I2SCodecStream i2s(LyratV43);

void setup() {
  // setup i2s and codec
  auto cfg = i2s.defaultConfig();
  cfg.sample_rate = 44100;
  cfg.bits_per_sample = 16;
  cfg.channels = 1;
  i2s.begin();
  // set volume
  i2s.setVolume(0.5);
}
