Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:

Use:

NSURLSessionConfiguration:backgroundSessionConfiguration:
instead of

NSURLSessionConfiguration:defaultSessionConfiguration
From the NSURLSessionConfiguration:backgroundSessionConfiguration: documentation:

Upload and download tasks in background sessions are performed by an external daemon instead of by the app itself. As a result, the transfers continue in the background even if the app is suspended, exits, or crashes.
So in your case, change:

sebmarkbage

var Bar1 = base => class extends base {
  componentWillMount(){
    super.componentWillMount();
    console.log('Bar1');
  }
};

var Bar2 = base => class extends base {
  componentWillMount(){
    super.componentWillMount();

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];
