Arduino Audio Tools – Downloading Files from the Internet to a SD Card

Quite some time ago, I tried to use the functionality of the Arduino Audio Tools to download a file from an URL and store it on a SD card, but I was running into some problems. I finally found the time to investigate the issue and I have the functionality finally working now:

#include "SD.h"
#include "AudioTools.h"

const char *ssid = "SSID";
const char *password = "password";
URLStream url(ssid, password); // Music Stream
StreamCopy copier; //(i2s, music, 1024); // copy music to i2s
File file; // final output stream

// Arduino Setup
void setup(void) {
    Serial.begin(115200);
    AudioLogger::instance().begin(Serial, AudioLogger::Info);

    // intialize SD
    if(!SD.begin()){   
        LOGE("SD failed");
        return;
    }

    // open music stream
    url.begin("https://pschatzmann.github.io/Resources/audio/audio-8000.raw");

    // copy file
    file = SD.open("/audio-8000.raw", FILE_WRITE);
    file.seek(0); // overwrite from beginning
    copier.begin(file, url);
    copier.copyAll();
    file.close();
}

void loop() {}
