The word "trans-muted" is not a recognized term in the English language, therefore, there cannot be any specific antonyms. However, we can look at the two separate words "trans" and "muted". "Trans" is a prefix meaning "across" or "beyond", while "muted" refers to a sound that has been softened or made less intense.
Antonyms for "trans" could be "in" or "non", while antonyms for "muted" could be "loud" or "intense". Therefore, we could conclude that potential antonyms for "trans-muted" could be "non-muted" or "intensely audible", but again, it is important to note that "trans-muted" is not a recognized word in the English language.
