Software
Since the researchers want to study digital effects that are easily accessible for post processing audio from an electric guitar, they decided to use Garageband. GarageBand is a software application for OS X and iOS that allows users to create music or podcasts. It is developed byApple Inc. as a part of the iLife software package on OS X. It is easily accessible because it comes along with OS X, so anyone with access to a mac will have access to garageband. The researcher will be using the OS X version of garageband for mac computers as opposed to the iOS version for Apple’s mobile devices. The researchers used Garageband ‘9 (version 5.1) for this study.
In addition to the standard tracks, Garageband allows for guitar-specific tracks. Guitar tracks can utilize a variety of simulated amplifiers, stomp boxes, and effects processors. These imitate popular hardware from companies known in the guitar and amplification industry, although there is no mention of which specific manufacturers and models by Apple.
Up to five simulated effects can be layered on top of the virtual amplifiers, which feature adjustable parameters including tone, reverb, and volume. Guitars can be connected to Macs using the built-in input (requires hardware that can produce a standard stereo signal using a 3.5mm output) or a USB interface. All digital audio effects used were taken from Garageband’s built-in library.
