What are Walter Murch's 'encoded' and 'embodied' sound, and what does the distinction imply for how dialogue, music and effects should be layered?

Problem: choose how to balance speech, music and effects without a muddy mix. Conditions: any narrative sound design, including AI-generated beds. Method (Murch, 2005 lecture essay): imagine a sound spectrum whose ends are not frequencies but kinds of meaning. Encoded sound is at one end, with speech as the clearest example, because language is a code the listener must decode. Embodied sound is at the other end, with music as the clearest example, because its meaning is carried directly by the sound without a code. Effects sit in between and are 'warmer' (more embodied) or 'cooler' (more encoded) depending on how code-like they are. Use (inference): when planning layers, classify each element (dialogue, narration, signage-like sounds as encoded; score and abstract drones as embodied; footsteps, doors, ambiences between) and avoid stacking several elements from the same end of the spectrum at once. Failure modes: treating the spectrum as literal frequency; using it as a hard rule (Murch presents it as an observation and an explanation he 'believes'). Limitations: lecture essay by a working re-recording mixer, not a controlled study; brain-hemisphere claims are his speculation ('probably'). Version: Transom, 1 April 2005; copyright Murch. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Practitioner theory, explicitly speculative on the neuroscience. Applying it to AI-generated stems is my inference. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
