Our contribution presents free guitar samples, their score, and documentation. While the original idea is to provide ecologically valid testing material for virtual auditory environments (VAEs), the use of the guitar samples is not restricted to this application and also permits various other, free, academic, and non-academic applications. In particular, the endeavor is part of a project of the
... [Show full abstract] German Acoustical Society (DEGA) and its TC on Virtual Acoustics that was launched in spring 2016. The project includes establishing suitable models of an extensible database of audio material. It considers public domain licenses, thinkable compensation of and contracts with musicians, and establishing best practice models for free, quotable, technically and musically well-documented, public domain audio content. More information about that project can be found in [1].
The public-domain guitar samples contribution we present here comprises two recording sessions of acoustic and electric guitar pieces. Both sessions were carried out in the same room, using the same recording equipment. They include microphone and direct-input signals of short guitar miniatures with the musical score, transfer functions (impulse responses) from the guitar position to each microphone, room reverberation time and noise floor measurements and recordings, and a detailed description of the used recording equipment including sensitivity information and transfer factors of the microphones and digital-to-analog converters. A brief overview of the first session is given in the following. The full details can be found in the documentation of the recording sessions which can be found here: https://opendata.iem.at/projects/dega_guitar_recordings/ .
