There’s no argument that the best acoustic guitar sound reproduction comes from placing a high-end condenser studio microphone in just the right position in front of the guitar. iRig Acoustic, when used with AmpliTube Acoustic, is designed to perfectly replicate that ideal mic placement and accurately capture the full frequency range, tonal character and complex harmonics and overtones of acoustic guitars. It's able to do this thanks to the combination of its uniquely designed microphone enclosure, which combines the latest MEMS (MicroElectrical-Mechanical System) microphone technology with an omnidirectional polar pattern, placement of the microphone just inside the sound hole where the output is optimal and the sound is very detailed and focused, and the “calibration” process that optimizes the guitar sound like it is being miked externally with a high quality studio microphone. These technologies combine to capture the "complete picture" of an acoustic guitar — every vibration and sonic interaction — unlike piezo-electric pickups or magnetics that just capture the vibrations of the body top or strings. Simply put, iRig Acoustic delivers a pure and full representation of an acoustic guitar's tonal characteristics.
