I'm working on a group project where we need to send an audio signal between two computers without using the internet or a local area network. We're considering using an auxiliary jack connector since it can function as both an emitter and a receptor. However, I'm not sure how to connect them correctly. Just plugging them in doesn't seem like it would work because each computer needs to process the signal in different ways. How can we set this up so that the sending computer recognizes the cable as a speaker and the receiving computer sees it as a mic?

It sounds like an interesting idea to transfer audio. If the goal is just to get audio from one machine to another, you can connect the audio out of one PC to the mic in of another. Just keep in mind that this will only send analog signals, so it won’t work for digital files.
If your goal is purely to send audio, just play the sound file on one PC through the speakers and use the other PC’s mic to record it. Simple, though not the most efficient way to transfer digital files without any other equipment.
Just a heads up, the output level from the sender is line level, which is higher than what the mic input can handle. You may need to build a small circuit to adjust the input level. If done properly, you can use encoding to send data, similar to how modems work. Though it sounds complicated, it’s definitely doable!
You'll want to ensure that both PCs have separate jacks for input and output. You can use a TRS cable: connect the sender's audio output to the receiver's mic. However, you’ll need to check the sound settings to set one as output and the other as input. This approach might be hard for transferring data since it's mainly for audio playback.
You might want to check out Virtual Audio Cable! It simulates an audio cable, which could help you establish a connection, but it might not work with your desire for a physical setup since you’re looking to actually use cables. You’d need to be sure it can translate your signals correctly.
I see, so it’s more about achieving a physical connection? Would Virtual Audio Cable even help with that?
Does that mean we’d have to play the audio on one PC and record it on the other? That sounds impractical!
