Wind and handling

Two enemies, two solutions

Wind and handling noise are not artistic problems — they are mechanical ones, and they have mechanical answers.

Wind ruins a take not by being loud but by being structureless. It couples directly with a capsule, forcing a large, low-frequency pressure wave across the diaphragm that the microphone was never designed to resolve. The result is not a recording of wind but a recording of capsule overload: a low rumble that buries everything, often clipping the input before the signal even reaches the recorder. A foam windshield reduces coupling at moderate speeds. At anything above a light breeze, a blimp — a rigid outer cage holding the microphone in suspension — combined with a fur or synthetic-fur cover (a deadcat or softie) is what works. The outer layer breaks up turbulent airflow before it can reach the cage; the cage isolates the capsule from the remaining vibration; the internal suspension absorbs what is left. The system is layers, not a single fix.

Handling noise enters from the opposite direction — through contact rather than air. A recordist grips a cable, adjusts a hand position, or sets a machine down, and the vibration travels up the body of the microphone to the capsule. The fix is decoupling. An elastic shockmount suspends the microphone in a cradle that absorbs contact vibration before it reaches the body. Coiled or loosely dressed cable also helps: a taut cable is a conduction path. A low-cut filter set at a conservative frequency can reduce what survives both, though filtering is always a last resort — it removes real information from the low end of field recording along with the noise.

The reason both problems matter beyond basic craft: a take contaminated by wind or handling cannot be composited cleanly with other material. The noise does not sit in an isolatable band. It is woven through the recording, and that makes it permanent.
