"I obfuscated our conversation with loud music to avoid recording."
The linked definition says:
The action of making something obscure, unclear, or unintelligible.
‘when confronted with sharp questions they resort to obfuscation’
[count noun] ‘ministers put up mealy-mouthed denials and obfuscations’
Origin: Late Middle English: from late Latin obfuscatio(n-), from obfuscare ‘to darken or obscure’ (see obfuscate).
The most up voted answer there (and the one I like) is mask. When I think of obfuscate, I think of manipulating information to confuse or misdirect someone's interpretation of a situation or a communication, so I was surprised to see this use.
Yes, sound is information in some sense, but the information we extract from the sound of speech is not the same as the initial waveforms and vibrations in the air.
Can one obfuscate a conversation by masking it acoustically? Is this a proper use of obfuscate, or is it a bit of a stretch?
