Play base64 audio string from Azure Blob service REST api with Javascript/Phonegap
Date : March 29 2020, 07:55 AM
I wish this helpful for you I have solved this by uploading the file as a byte[] instead of base64 encoded string. The file get's stored as an .aac audio file in blob storage and can be played directly from storage. For uploading i used the following code: var reader = new FileReader();
reader.onloadend = function (evt) {
if (evt.target.readyState === FileReader.DONE) { // DONE == 2
var RETRY_TIMEOUT_SECONDS = 5;
var NUMBER_OF_RETRIES = 3;
var requestData = new Uint8Array(evt.target.result);
$.ajax({
url: url,
type: "PUT",
data: requestData,
processData: false,
beforeSend: function (xhr) {
xhr.setRequestHeader('x-ms-blob-type', 'BlockBlob');
},
tryCount: 0,
retryLimit: NUMBER_OF_RETRIES,
success: function (data, status) {
console.log(status);
},
error: function (xhr, desc, err) {
if (xhr.status === 403) {
console.log("Access denied, the assigned upload time has been exeeded");
} else {
this.tryCount += 1;
if (this.tryCount <= this.retryLimit) {
console.log("Retrying transmission");
setTimeout($.ajax(this), RETRY_TIMEOUT_SECONDS * 1000);
return;
}
}
console.log(desc);
console.log(err);
}
});
}
};
// Read the file as a byte[]
reader.readAsArrayBuffer(dbFile);

Using AudioTrack to play base64 encoded audio String (converted to byte array) just produces white noise
Date : March 29 2020, 07:55 AM
this will help Your audio data is encoded with Opus codec with a sample rate of 48000 Hz (detected by FFmpeg). You have given wrong sample rate as a parameter to the AudioTrack constructor (given 44100 but it's 48000) and also it's encoded with a codec, and AudioTrack expects raw/decoded PCM audio so it could be the reason for the white noise you are hearing. In order to play the audio correctly, first convert it to raw PCM audio data then encode it with Base64.
