Sometimes we need to get regular analog audio into our machine, and the only way to achieve that is with the help of a USB audio interface. But you need not to worry, as these devices are both becoming more popular, very easy to use and are budget friendly.
Line 6 POD Studio UX2
The Line 6 POD Studio UX2 is the model you will want if you're a musician, have a guitar and work on a Mac. We love the performance in relation to the reasonable price ($159 over at Amazon). The UX2 is primarily geared towards guitarists and singers, and setup can initially be a little overwhelming, but in the end the features span well from beginner to advanced. Despite the plastic casing, in our opinion, the UX2 has the most stylish case design available today. The back panel boasts seven 6.3 mm jacks for line-in, foot switch, monitor and line-thru audio. We also like the dual XLR mic inputs placed on the front of the unit for easy connecting.
Avid Recording Studio
Avid Recording Studio offers a fairly straightforward way to convert your Mac or PC setup into a full-featured studio. The device allows you to capture guitars, other instruments, and vocals in pristine, 24-bit/48 kHz quality; budget minded musicians will like that iPro Tools SE recording software and M-Audio Fast Track audio interface are both thrown in. It's easy to fatten the sound of your instrumentals, deepen the groove, and get clean, pristine tones with Pro Tools SE like a modern day digital Phil Spector. You can also add backing tracks with loops from a huge included library.

It's the portability of this set up and the small footprint that is really it's selling point. Combined with a laptop , the Cakewalk allows easy recording and playback at 24-bit/96 kHz, XLR inputs, alongside an amp simulator, chorus, delay, reverb and enhancer.
