I was trying to say to a friend of mine "We need to speak in Latin through audio" and I just noticed I have no idea the appropriate word for "audio" in Latin. And it doesn't help the fact that the word "audio" is Latin for "I hear" lol. Is there a word already invented to be used in Latin for the modern concept of "audio" (as in an audio file you send to someone)? If so, how does one go about saying it? Is there any dictionary of Living Latin you guys go through to find words and expressions for our modern needs?
How about sonus, literally "sound", or vox, literally "voice", depending on context?
In other words, I would say "we need to converse by voice" (voce), or "I'm sending an image file and a sound file" (sonī). The latter trick, the genitive of the noun for "a sound", is often used in Modern Greek (ήχου), which seems like a good precedent.
