All iPhones and iPod Touch 2G and above have 2 possible audio input sources, in addition to the integrated mic on iPhones.Jack Input
The headphone jack on your iDevice is a 4 pin one, as seen here
You have 2 options to use this mono input.
Build or buy a custom splitter cable :
That will allow you to plug-in anything on the microphone pin. But beware of this things :
1. The headset microphone input is very sensitive (it expects a low-level microphone signal).
2. A bias voltage is present on the headset input to power electret condenser microphone capsules (used by the afore-mentioned microphone accessories).
3. The headset input expects to see a particular load in order to signal the OS that an external microphone is present.

For example, the PRS GuitarBud
is part of this family of cable. It splits the 4 pin jack into a 3.5mm female stereo jack output and a 6.5mm male mono jack input usually used for electric guitars.Update
: Much better quality cables than the GuitarBud exist now. They have some added circuitry to solve the above-mentioned problems. These are the IK Multimedia iRig
and the Peavey AmpKit LinK
Use an headset microphone :
That's what this input was designed for, so no voltage/load problem here.
You can use any kind of headset, like the Apple official one
. If you want to be able to use any kind of headphones with the mic, you can use accessories like the Philips SHH1610
which simply is a mic + 3.5mm female stereo jack output.Warning
: Micro mics, such as the ThumbTack
are useless with Everyday Looper as they don't allow you to hear your already recorded tracks.Dock Input
Hidden in the dock, there is a stereo line-in input. However Everyday Looper only records in mono, so it will only use one of the two channel.
The accessories have to be certified as "Made For iPod", so you can't build a custom cable yourself.
There is a few accessories that uses the dock connector, like the Alesis ProTrack
. It offers vast input options : XLR, Jack or Mics. However, this device provides input only, that means you will need to plug your headphones in the iPhone to hear your tracks. For iPod Touch users, it's problematic as you can't plug anything in the jack once connected to the ProTrack (jack is at the bottom, next to the dock connector). Be warned.
For more information on this input, you can read this post
from the still excellent faberacoutical blog ^^.Warning
: The stereo line input doesn't work the same way on 4G and above iDevices ! For now there isn't any available dock input accessories compatible with the iPhone 4+ / iPod Touch 4G+ / iPad 1+. Upcoming compatible products are the Sonoma Wire Works GuitarJack 2
and the Apogee Jam
.Camera Connection Kit (iPad only)
The Camera Connection Kit
provides a Dock to USB adapter. This way, you can use a standard USB sound card if it meets the following requirements :
- USB Audio Class 1 compatible (hint : works without drivers on MAC / Windows)
- Doesn't draw much current (use a powered USB hub if it does)
- Sometimes some magic mojo, so better check this list
If you are looking for one of the cheapest working card, there seems to be a consensus around the Behringer UCA 202
