Ears, rooms, and microphones: perception and sound capture

Every sample you mangle on stage started as air pressure hitting a diaphragm in a real room. Live coders and electronic producers who record their own material — a vocal fragment for a dub techno pad, a struck object for a granular engine, field ambience for a set’s intro — get radically better source material when they understand what happens between the sound source and the recorder. This module builds toward one authentic whole task: planning a complete mic setup for a single source in a small room, the exact scenario of a bedroom studio or improvised recording session.

The arc starts supported: first, sketch how a signal chain converts pressure to voltage, leaning on the condenser and dynamic microphone atoms as just-in-time references for how each transducer works and what that implies (phantom power, robustness, sensitivity). Next, practice choosing a pickup: the polar patterns atom is your pointer for predicting what a cardioid rejects versus what an omni hears, and the mid-side decoding atom shows how a two-mic matrix yields adjustable stereo width. Then the room enters: use the standing-waves atom to predict which low frequencies a given room dimension will exaggerate or null, and the critical-distance atom to reason about how far back you can place a mic before the reverberant field swallows the direct sound. The capstone integrates all of this unsupported.

The six required atoms gate the capstone — each corresponds to a decision you must justify in the plan. The supporting atoms enrich the picture: perceptual thresholds (Haas fusion, binaural cues, the rhythm–pitch continuum) explain why capture choices are audible at all, while the soundsystem-resonance anecdote and analog-character material connect room physics and transducer imperfection to real performance practice.
