Nowadays, you don't need crazy equipment to broadcast on location. Chances are you have everything you need already in your pocket. We're talking, of course, about your mobile phone.

Certain apps turn mobile phones into neat little broadcasting centres. Ready for you to fire what's happening around you straight to your radio station. Daniel Nöthen (the creator of BUTT) being the helpful guy he is, has made a robust yet low-cost solution for broadcasting from your iPhone (or iPad).

Introducing... iziCast!

iziCast is a client broadcaster for Radio.co broadcasters, as well as Icecast and Shoutcast hosted radio stations that work exclusively on iPhones and iPads.' Many radio stations use client broadcasters like BUTT but this does not work on iPhones or iPads. iziCast is a solution for those devices.

Purchase and Download iziCast

iziCast is an app, so is available from the Apple Store here.

iziCast costs £6.99/€7.99/$7.99. You can also buy some functions to edit audio for as little as £0.89/€0.99/$0.99 each.

What iziCast Offers Broadcasters

iziCast takes the audio from your iPhone or iPad and pushes it out to your Shoutcast or Icecast radio station. So this means you can broadcast via your iPhone. iziCast has 5 key functions:
