Abstract
Denne afhandling undersøger, om mikrofonarrays kan gøres tilgængelige for hjemmebrugere gennem en brugervenlig, open source VST-plugin til beamforming. Med udgangspunkt i en vision om at demokratisere rumlig lyd via software gennemgås de centrale principper for bølgeudbredelse, aperturer, retningskarakteristik og diskrete sensorarrays som teoretisk fundament. En status over eksisterende hardware og software danner baggrund for designmål, kompatibilitet og brugeroplevelse i en JUCE-baseret plugin. Projektet skitserer valgte beamformingtilgange samt planlagt implementering og evaluering, herunder optagelse af prøvespor og vurdering af arrayets ydeevne med mål som array gain, white noise gain og beampattern. Konkrete resultater fremgår ikke af dette uddrag; målet er at sænke adgangsbarrieren for mikrofonarray-optagelser med et gratis og let anvendeligt værktøj.
This thesis investigates whether microphone array recording can be popularized for home users through an easy-to-use, open-source VST beamforming plugin. Motivated by a vision to democratize spatial audio via software, it presents the theoretical foundations of wave propagation, apertures, directivity, and discrete sensor arrays. A survey of current hardware and software informs design goals, compatibility, and user experience for a JUCE-based plugin. The project outlines selected beamforming approaches and the planned implementation and evaluation, including recording sample tracks and assessing array performance with measures such as array gain, white noise gain, and beampattern. Specific findings are not provided in this excerpt; the overall aim is to lower the barrier to microphone array recording with a free and accessible tool.
