I got asked the question do I lose out on sound design work because I only have a stereo setup. This would be true if I didn’t collaborate with people that had a 5.1 surround sound setup. Collaboration is an important part in freelance life and especially for bigger projects with tighter deadlines.
You have probably come across the term ISO track in audio as it has now become an industry standard for drama and other location sound work.
ISO is short for isolated. Isolated from all other audio signals. Now with better technology at the start of the 2000’s audio recorders record a Left/Right, Aux and ISO’s.
