Hello all! I am trying to configure two Teensy 3.6 with nRF24L01 modules to transmit wireless audio with CD quality (16 bits @ 44 kHz). The audio will be gathered from the Audio Board in the Tx and then played in another Audio Board in the Rx.
So far, what I get in the other side is lots of noise when playing audio in the Tx. I am not sure if I am sending/receiving the full packets. Can you take a look and let me know if you have any advice, please?

I am copying the variables initialized and the update functions, so I do not mess the post with the full code.

In the Tx side, inside the update() function and after initializing the radio object and its methods, I have:

byte data[32]; 
int8_t datos[32];
  audio_block_t *cosa;

  cosa = receiveReadOnly(0);


  for(int i = 0; i < 32; i++){
    datos[i] = cosa->data[i];  
  for(int i = 0; i < 4; i++){
    radio.writeFast(&(datos[i]), 32, 1);
In the Rx side:

const int payload = 64;
uint16_t audioFull[payload];

if (radio.available())
    for(int i = 0; i < payload; i++){
      radio.read(&audioFull[i*16], sizeof(audioFull));
    int16_t* bfr = queue.getBuffer();
    for(int i = 0; i < payload; i++){
      bfr[i] = audioFull[i];
