Media file encoding in Base64

To upload a media file as an audio it must be properly encoded as a Base64 string, as defined in RFC 4648; without whitespace, line breaks nor any other unsupported characters.

Encoding examples

The following examples read file.mp3 and print it as a valid Base64 string.

Base64 encoding methods vary between environments and programming languages.

Linux

base64 -w 0 {file.mp3}

macOS

base64 --input {file.mp3}

JavaScript

const fs = require("fs");

const content = fs.readFileSync("{file.mp3}");
const encodedString = content.toString("base64");

console.log(encodedString);

Python

from base64 import b64encode

content = open("{file.mp3}", "rb").read()
encoded_string = b64encode(content).decode()

print(encoded_string)
