IPA: /ʌnˈmɒdʒʊleɪtɪd/
KK: /ʌnˈmɒdʒʊleɪtɪd/
Describing something that has not been changed or adjusted in any way.
The sound remained unmodulated throughout the entire performance.
Unmodulated → It is formed from "un-" (meaning not) and "modulatus" (from Latin, meaning measured or adjusted). The word "unmodulated" means not measured or adjusted, indicating a lack of variation or control in tone or frequency.
Think of 'not' ('un-') having any 'measured' ('modulatus') changes — that's why unmodulated means lacking variation.
