I have a BNC microphone and need to connect it to a PC.

I have found some video BNC computer cards used for CCTV cameras, but I just want audio only.
Is it possible to connect BNC Audio to a PC?

 

Usually pcs have a 3.5mm jack socket on the sound card Blue or Red, if so you could cut off the plug and replace it, or get an adapter.

I actually have 4 microphones with a BNC output signal cable. I need to take the raw signal from each microphone and feed it into Python.
Is it possible to get an audio only BNC input computer card to get the raw signal from the BNC microphones?
Microphone will have a power supply box, I only need a way of getting the signal from the microphone to my PC

 

You can get adapters for Bnc to 3.5mm Jack plugs.

No, it is not possible unless you want an audio card from the 1980s (or 1990s if you find a PC made in Easter Europe). Unfortunately, these will not likely fit a modern motherboard.

You can look for a data acquisition card (ADC) with a BNC connection but Python may not recognize it as an audio card.

 

I doubt you will find an audio card with BNC input connectors. The typical audio card uses a 3.5mm jack. You can find BNC to 3.5 mm adapters. The link being a single example. The average audio card allows for a single stereo input so as to 4 mono channels you are on your own. Depends on exactly what you want to do since you mention 4 microphones.
