I'm trying to get the sample rate information of a file before uploading it to server, need to access this for some validation purpose on browser.
What I did so far
let reader = new FileReader();
reader.readAsArrayBuffer(e.files[0]);
reader.onload = function (event) {
let buffer = reader.result;
let AudioContext = window.AudioContext || window.webkitAudioContext;
let context = new AudioContext();
context.decodeAudioData(buffer, function (buffer1) {
console.log(buffer1.sampleRate);
});
}
But this always gives some constant result regardless of file selected. Can anyone suggest what is wrong here or any other idea to achieve the same?
