Viewers will often accept a simple picture more readily than unclear dialogue. Clean interview sound begins before the record button: with the room, microphone position, clothing, crew movement and monitoring. A short sound check can prevent an otherwise strong interview from becoming difficult to use.
Listen to the space before setting up
Stand quietly in the intended recording position and listen. Air-conditioning, traffic, phones, lights, nearby conversations and moving chairs can all become more noticeable through a microphone. Identify what can be switched off, moved or scheduled around.
Also listen for the character of the room. Hard, empty spaces reflect more sound, while soft surfaces and acoustic treatment can reduce unwanted reflections. The objective is not always a completely dry recording, but speech should remain clear and consistent.
Put the microphone close enough
Distance is one of the biggest influences on dialogue quality. A microphone positioned close to the speaker usually captures more voice and less room. Whether the production uses a lavalier, boom or another approach, placement should remain consistent as the guest moves naturally.
Check lavalier placement for clothing rustle, jewellery and hair contact. With a boom, keep the microphone close without entering the frame or creating a shadow. Placement should be checked again after wardrobe or camera changes.
Monitor the actual recording
Meters show level, but headphones reveal hum, distortion, interference and handling noise. Someone should listen throughout the interview, not only during the initial test. If a problem appears, stop and fix it while the speaker is still available.
Set conservative levels that leave room for laughter or a louder answer. A clean recording with headroom is more useful than one that clips at its strongest moment.
Capture room tone and useful redundancy
Record a short period of silence with everyone in position. This room tone can help an editor smooth gaps between answers. Where the production allows it, a second recording path can provide protection against a cable, battery or placement problem.
Before the guest leaves, review a representative section with both picture and sound. Do not rely only on the fact that the recorder was running.
