Hello Phil, Fatal error: AudioBoard.h: No such file or directory I installed your file “arduino-audio-tools-main.zip” via the Arduino IDE. What am I doing wrong? |

Don't use an AudioBoardStream if you dont have an AudioKit or another Audio Board ! |

I believe FileLoop.h and AudioSourceSD.h do not work together. error: #include expects "FILENAME" or Here is an excerpt from my sketch. #include <SPI.h> //Uncomment and set up if you want to use custom pins for the SPI communication //#define TFT_WIDTH 320 #define I2S_PORT I2S_NUM_0 // MAX98357 // Audio parameters // Channels // Buffer size (frames, not samples) // Stereo buffer: Left, Right #define PATH "/doorbell" //int PIN_AUDIO_KIT_SD_CARD_CS = 10; |

This does not make any sense: AudioSourceSD is for the AudioPlayer! |

And how can I mount the SD card without AudioSourceSD? |

This has nothing to do with my library: just google the topic how to work with SD cards in Arduino or look at the example that I have sent you! |

Hello Phil, I have mountet my sd card, and the player stopped working. This is my output from the serial monitor. FILE: doorbell2-6450.mp3 SIZE: 196800 |

Hello Phil, this is my sketch. In the moment I have no sound :-(. #include "FS.h" Adafruit_VL6180X vl = Adafruit_VL6180X(); //Uncomment and set up if you want to use custom pins for the SPI communication #define I2S_PORT I2S_NUM_0 // MAX98357 // Audio parameters // Channels // Buffer size (frames, not samples) // Stereo buffer: Left, Right I2SStream i2s; void setup() { SPI.begin(sck, miso, mosi, cs); uint8_t cardType = SD.cardType(); if (cardType == CARD_NONE) { Serial.print("SD Card Type: "); uint64_t cardSize = SD.cardSize() / (1024 * 1024); } Serial.println("Adafruit VL6180x test!"); AudioToolsLogger.begin(Serial, AudioToolsLogLevel::Info); // setup I2S based on sampling rate provided by decoder } void loop() { copier.copy(); } |

This is the output of my serial monitor. SD Card Type: SDHC |

I assume that you have many other copy lines after that! If this is the case the overall processing logic is working. If you dont get any audio you need to figure out the root cause:
Here are some more hints |

Hello Phil //I assume that you have many other copy lines after that! If this is the case the overall processing logic is working. Yes, that's right. //If you dont get any audio you need to figure out the root cause: The sound runs through the small MAX98357 amplifier. // Does the Audio Output work: did you test e.g. with a sine tone ? // Does the decoding with the file w/o loop work ? // Does the decoding with another mp3 file work ? //Is your mp3 file really 24000 / channels: 1 ? My first guess would be that this is just one more case which excessive metadata. I have set a sample rate of 44100, which also works with the audio player. When I transfer my MAX98357 pins to the i2s, it crashes. There is no transmission in the loop. Could that possibly be the reason? |

Yes, if the DAC does not get any signal, you will not hear anything... |

Hello Phil, okay it funzt. Thanks for you help :-) |

The AudioPlayer is not designed for this.
Why don't you just use a FileLoop like in this example ?
