<p>Plugging this simple little Apple connector into your iPad or iPhone provides you with a USB input, into which you can plug a myriad of different devices. Some of these (microphones with USB out, guitar inputs) are listed here, but there are hundreds of others available. My daughter&#39;s electric keyboard, for example, can interface with my iPad using this connection kit.</p><p>Requires the Apple Lightning to USB Adapter. A simple little device that converts your analog electric guitar signal to USB, which can then be plugged into your iPad. Just run your standard 1/4&#34; guitar cable directly from your instrument into the UCG102, and you can plug that into your iPad (via the Camera Connection Kit). The device features a high/low gain switch and a clip warning light.</p><p>Requires the Apple Camera Connection Kit. I love this odd-looking and relatively inexpensive little microphone for quickly and easily recording acoustic instruments. You simply plug a USB cable from the microphone into your device and you are ready to record. I&#39;ve used the Blue for recording acoustic guitar, full bands, spoken audio, and some lead vocals, and have been impressed with the capture quality. A three-stop setting on the microphone allows you to control gain.</p><p>The first generations of devices designed to allow you to record electric guitars through your iPhone shared a common flaw - they used the analog audio-in via the phone&#39;s headphone jack. This resulted in low-quality recordings plagued by &#34;crosstalk&#34; and other technical issues. The tiny Apogee Jam, although slightly more expensive than some of these cheaper options, uses the iPhone/iPad&#39;s dock connector for a much higher quality data transfer. In simple terms, this allows for a much higher quality recording. With the Apogee Jam, you can plug your electric instrument in to one end of the unit via a standard connect 1/4&#34; cable, and into the other end plug your iPhone/iPad using the provided adapters. And, as simple as that, you&#39;re rigged to record on your phone or tablet.</p><p>Full disclosure - I haven&#39;t tried the Blue Mikey. But the microphone does look promising - it interacts with the iPhone&#39;s digital port, rather than the inferior analog audio-in accessible through the iPhone&#39;s headphone jack (which is what allows Apple to include a microphone in their headphones). Using this microphone, you&#39;ll be able to record any analog sound on your iPhone - acoustic guitars or other instruments, vocals, etc.</p>Once only available for desktops, Apple&#39;s GarageBand is now available for the iPhone and iPad. The functionality they&#39;ve packed into this low-priced app is truly impressive - for $5 you get multi-track recording, effects pedals, &#34;smart&#34; drum and keyboard tracks, and much more.Although not an essential purchase for those just getting their feet wet in recording on their iDevice, Audiobus is a handy tool that allows different audio apps to interact with each other... for example allowing you to record the guitar sound you&#39;ve dialed in via the AmpliTube app using the GarageBand app.Here is a straightforward, free app that allows guitarists to tune their instruments via their iPhone. Pretty handy stuff.
