Someone was throwing out a very large piece of foamcore and, as I’m in K-12 budget world, I grabbed it for re-use. The first purpose I used it for was as a light reflector for video and photography shoots. Then a new need arose. Our English Learning Acquisition (ELA) office asked me to make an audio recording of 4 narrators who would act out a screencast sequence. I already had microphones and a usb audio mixer, but I knew that I needed some separation from each microphone during the live recording. I grabbed the oversize piece of foamcore, cut it in half, and made two slits in the center, just going halfway up the edge.
I then slid them together to form a +plus sign and set it on the table. I placed microphones at each corner and proceeded with the recording of the narration track.
You can take a look/listen here to evaluate the results.
The only thing I would do in the future for this type of setup is to get an even larger piece of foamcore. This one was originally 3′ x 4′ before I cut it into two pieces. I might have even added some sound absorbing material to the sides. But in any case, I’m ready for next time.
I hope this quick tip helps you if you ever need to make a low-budget audio recording of multiple voices.
Always innovating and problem-solving, Paul.
