      Good morning. I've been playing around with my SPRESENSE board and have the RECORDER_WAV example up and running perfectly. Now I'm trying to edit the code to be able to perform multiple recordings...

      Ex) Record a 10 second wav file called Audio_000.wav and save to SD Card. Then record another 10 second wav file called Audio_001.wav and save to SD Card. So on and so on.

      Since the Camera example does something similar with its JPG files, I attempted using the same sort of syntax with my new RECORDER_WAV file, but am running into a sleuth of issues...

      My attempt is pasted below, along with the Serial monitor output. Basically I attempted to use an IF statement to record 10 WAV files. I'm thinking I might be approaching this issue incorrectly. Any help or guidance would be greatly appreciated!

      #include <SDHCI.h>
#include <Audio.h>
#include <stdio.h>

#include <arch/board/board.h>

SDClass theSD;
AudioClass *theAudio;

File myFile;
int file_count = 0;

bool ErrEnd = false;

static void audio_attention_cb(const ErrorAttentionParam *atprm)
{
  puts("Attention!");
  
  if (atprm->error_code >= AS_ATTENTION_CODE_WARNING)
    {
      ErrEnd = true;
   }
}

static const uint32_t recoding_sampling_rate = 48000;
static const uint8_t  recoding_cannel_number = 4;
static const uint8_t  recoding_bit_length = 16;
static const uint32_t recoding_time = 10;
static const int32_t recoding_byte_per_second = recoding_sampling_rate *
                                                recoding_cannel_number *
                                                recoding_bit_length / 8;

        Just took a quick look at your code:

        Isn't it so that if this line err = theAudio->readFrames(myFile); is ok you will exit and enter the loop() function again and start the recorder again without ever have stopped it first.

        

void loop() 
{
  if (file_count < 10)
  {
    char filename[16] = {0};
    sprintf(filename, "Test%03d.wav", file_count);
    myFile = theSD.open(filename, FILE_WRITE);
    
  if (!myFile)
    {
      printf("File open error\n");
      exit(1);
    }

  theAudio->writeWavHeader(myFile);
  puts("Write Header!");

  theAudio->startRecorder();
  puts("Recording Start!");

  file_count++;

  err_t err;
  
  if (theAudio->getRecordingSize() > recoding_size)
    {
      theAudio->stopRecorder();
      sleep(1);
      err = theAudio->readFrames(myFile);

      goto exitRecording;
    }

  err = theAudio->readFrames(myFile);

  if (err != AUDIOLIB_ECODE_OK)
    {
      printf("File End! =%d\n",err);
      theAudio->stopRecorder();
      goto exitRecording;
    }

  if (ErrEnd)
    {
      printf("Error End\n");
      theAudio->stopRecorder();
      goto exitRecording;
    }
  }
  
  return;

exitRecording:

  theAudio->closeOutputFile(myFile);
  myFile.close();
  
  theAudio->setReadyMode();
  theAudio->end();
  
  puts("End Recording");
  exit(1);
}

          Thanks for the quick response Karl. I actually ended up rewriting my code once I found Ben Eaton's code in the 'Recording at 192khz freezes' thread below, since he seems to be attempting the same this as me.

          My new program works well...for a random amount of time. Eventually it throws up the following error:

          Attention: module[4][0] attention id[1]/code[6] (objects/media_recorder/audio_recorder_sink.cpp L84)

          I can't seem to find a pattern for what could be causing this issue.

          Here is my code:

          #include <SDHCI.h>
#include <Audio.h>
#include <GNSS.h>

#include <arch/board/board.h>

SDClass theSD;
AudioClass *theAudio;
int file_count = 0;
File myFile;

bool ErrEnd = false;

// When audio internal error occurs, this function will be called back.
static void audio_attention_cb(const ErrorAttentionParam *atprm)
{
  puts("Attention!\n");
  
  if (atprm->error_code >= AS_ATTENTION_CODE_WARNING)
    {
      ErrEnd = true;
   }
}

//Sampling Rate (16000 or 48000)
static const uint32_t recording_sampling_rate = 48000;

//Input Mic Channels (1, 2, or 4)
static const uint8_t  recording_channel_number = 4;

//Audio Bit Length (16 or 24)
static const uint8_t  recording_bit_length = 16;

//Recording Time (Seconds)
static const uint32_t recording_time = 10;

//Bytes per Second
static const int32_t recording_byte_per_second = recording_sampling_rate *
                                                recording_channel_number *
                                                recording_bit_length / 8;
//Total WAV File Size
static const int32_t recording_size = recording_byte_per_second * recording_time;

void setup()
{ 
  theAudio = AudioClass::getInstance();

  theAudio->begin(audio_attention_cb);

  puts("Initializing the Audio Library...\n");

  /* Select input device as microphone */
    theAudio->setRecorderMode(AS_SETRECDR_STS_INPUTDEVICE_MIC, 210); //210 = 21.0 dB Mic Gain
    theAudio->initRecorder(AS_CODECTYPE_WAV,"/mnt/spif/BIN",recording_sampling_rate,recording_bit_length,recording_channel_number);
  puts("Setting up the Recorder...\n");

  /* Open file for data write on SD card */
  myFile = theSD.open("Sound.wav", FILE_WRITE);

            I added this snippet you mentioned in another thread with the same error:

            static void audio_attention_cb(const ErrorAttentionParam *atprm)
{
  puts("Attention!");

  switch (atprm->error_code) {
    case AS_ATTENTION_CODE_INFORMATION:
    case AS_ATTENTION_CODE_WARNING    :
      ErrEnd = false;
      break;
    case AS_ATTENTION_CODE_ERROR      :
    case AS_ATTENTION_CODE_FATAL      :
    default:
      ErrEnd = true;
  }
}

            Program ran fine until it got to the 7th file and got this error:

            Attention: module[4][0] attention id[1]/code[6] (objects/media_recorder/audio_recorder_sink.cpp L84)
Attention!

            Then the program froze and I had to manually reset it.

            Also, I am using a 64GB SanDisk Ultra microSD Card.

            Thanks!

              So I've been going through documentation and it looks like I may be running into a "FIFO Overflow" issue: AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW

              And the error information states:

              Simple fifo between application and sdk became full. Extraction speed
may be slower than Insertion. Coordinate task priority of application
to avoid queue remain increaseing.

              Also saw recommendations to increase task priority or increase the buffer size.

              I'm a bit lost and am not sure where to go from here. Would really appreciate any guidance anyone can provide...

              Thank you!

                Hi,

                This is a known issue. I have found a temporary solution for now. Unfortunately, this requires that you build the Spresense Arduino package again. You can use this: https://github.com/sonydevworld/spresense-arduino-compatible

                Currently, when an error is detected, the Audio module stops working. However, this can be changed and when FIFO OVERFLOW is detected, samples can be dropped instead.

                As a result, the application does not finish recording, but on the other hand does not guarantee that all samples will be saved.

                Solution:

                • Find function bool AudioRecorderSink::write(const AudioRecSinkData_s &param) in the file sdk/modules/audio/objects/media_recorder/audio_recorder_sink.cpp

                • Comment line number 84.

                • Return true instead of false on line number 85.

                After the changes, the function should look like this:

                bool AudioRecorderSink::write(const AudioRecSinkData_s &param)
{
  if (param.byte_size > 0) {
    if (CMN_SimpleFifoGetVacantSize(static_cast<CMN_SimpleFifoHandle *>
        (m_output_device_hdlr.simple_fifo_handler)) < param.byte_size)
      {
        // MEDIA_RECORDER_WARN(AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW);
        return true;
      }

    if (CMN_SimpleFifoOffer(static_cast<CMN_SimpleFifoHandle *>
        (m_output_device_hdlr.simple_fifo_handler),
        static_cast<const void*>(param.mh.getVa()), param.byte_size) == 0)
      {
        MEDIA_RECORDER_WARN(AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW);
        return false;
      }

    m_output_device_hdlr.callback_function(param.byte_size);
  }
  return true;
}

                This is only a temporary solution. If I find other, I will let you know.
