For all of my voice overs i’ve been using an USB microphone, but my laptop already has a stereo mic input so i thought maybe i should free one USB port and use that input, and i couldn’t just go and buy a mic that i may not use for log.
Making a stereo electret microphone is easy especially it needs no power or other components beside the electret microphone capsules.
After i took a look on my junk boxes i found two identical electret capsules, i gathered the needed parts and i made a video of making it.
