What is Chion's 'added value' and how can I use its six registers to decide what a generated sound should add to a shot?

Problem: Generated sound is often prompted by naming the object ('rain') rather than the effect on the image. Conditions: shots where the picture alone is neutral or ambiguous. Method: the lexicon lists six registers of added value (sensory, informative, semantic, narrative, structural, expressive). Pick the register the shot needs, then prompt for that: e.g. sensory (texture, temperature, energy), informative (space, time, cause), expressive (emotional colour). Because attention is on the screen, the audience attributes the sound's contribution to the image, so a sound layer can change how a shot reads without altering pixels. Example (inference): the same locked wide shot with a dry close room tone versus a cold reverberant hum reads as a different place. Failure modes: sound that contradicts the image's information (semantic clash) is read as an error, not a nuance. Limitations: secondary source; the 'six registers' is the page's summary of Chion. Version/date: as fetched. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction folded 2026-10-24 from C3-B733-07 (curator-reviewed discovery audit): Problem. C3-B722-02 states that sound contradicting the image's information (semantic clash) is read as an error, not a nuance. Conditions. sonicfield.org wiki page 'added value' (secondary summary of Chion). Correction. The page lists semantic added value as sound inflecting the meaning of what is shown and directing interpretation; it does not say contradictory sound is read as an error. That claim is the summary author's inference. Failure modes. Not stated by the source. Limitations. Secondary source. Version/date. As fetched. Limitations: Secondary lexicon summary; Chion primary not read; prompting advice is untested inference. Corrected by C3-B733-07; where the correction disagrees, the correction governs. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
