A microphone always form by mic and cable ,mic let your sound source collect into the device and away from it.
Your best choice for the PC is electronic condenser mic KD95 and KD96.No require a battery.the pc will drive almost anything plug them into.to make up the camera and pc’s audio shortcomings.
Use the audio on your DSLR for syncing only, and consider mounting the recorder on a monopod (making a decent ad-hoc boom) rather than on a DSLR (Actually for the DSLR built in mics will pick up lots of camera noise, so you need connect a good quality dslr camera microphone to the camera where the visuals are being recorded). Also, having the recorder well away from your PC again increases audio quality (PCs are actually very noisy when you want to create broadcast audio!).
A mic that plugs into your PC/DSLR is another option, but note that the audio amplifiers in your DSLR are typically garbage.Like a standalone recorder has better visual feedback and specific microphone have more pro audio features (proper limiting, higher dynamic range a every stage of the recording process, recording audio in a non lossy format, easier to match sound sources because you can specify gain better,value better and voice control etc).
You also need choose different mic for different types of audio depending on whether you are recording directional audio (vocals, live streaming,vlogger etc) and ambient, also need according to your device to choose a type of microphone,so better not use one mic for all the device?
