Field recording is any audio visual (AV) recording that is captured or produced outside a traditional recording studio. Field recording occurs in multiple industries, including broadcast, film and television and research. Field recordists must overcome challenges not found in a purpose built facility, such as lack of power, limited microphone resources and on-sight noise. Specialist AV euipment includes portable digital recorders, which negates the need for laptops with audio recording software, and video microphones, which are highly directional and lightweight. Respected audio recorder expert brands are Zoom and Tascam, which are both proudly carried at Swamp!
