There’s been lots of debate about audio input devices of late so you might want to check out Formal’s guide to making a cheap audio in cable here. Clip to Evernote


  1. I made one like this using a $5 ebay cable and it worked like a champ …. probably sounds just as good as the expensive vendor ones, you just have to make sure you don't put too much volume in it. Nice!

  2. I had already made one myself with a videocamera cable! But thanks for the guide nonetheless 🙂
    The main problem is that the iphone expects a mic input so line in signals will clip… I was thinking about adding a small potentiometer to reduce the incoming voltage on too hot signals, but I'm not sure that will do the trick…
