This recording session was quite a rare, novel experience for Li Wei.
Technology in this era had yet to advance to the point of modern recording studios, with piles of sound-absorbing material and dedicated soundproof booths.
But as long as you kept your thinking on track, there were always more solutions than problems. Ovelia's solution to this particular difficulty was simple.
Just build the radio station somewhere nobody lived.
And so the radio station had been built in a rather remote, uninhabited area.
The recording studio was even underground. Of course, to Li Wei, it felt more like one of those cheap modern karaoke rooms... Oh well, this would have to do for now.
Naturally, a microphone was used to capture the sound, but Li Wei could make neither head nor tail of this era's recording machines. Had they used records or magnetic tapes, he could at least have understood something of how they worked. But turning recordings into Punched Cards went a little beyond his understanding.
"By the way, how exactly does this recording machine make Music Cards?"
Li Wei studied the recording machine in front of him with puzzlement. In this era, an ordinary recording machine was about the size of a water-cooler jug and usually sat on a table. This one was larger, taking up almost half a wall, with numerous buttons and keyboards on its front. If not for the steam pipes and exhaust vents beside it, it would have looked very high-tech.
Although, by this era's standards, it certainly was high-tech.
"Oh, that's very simple, Mr. Li Wei."
Kia was also quite interested in the recording machine, and when she heard Li Wei's question, she hurried to explain.
"Sound consists of vibrations, so the recording machine captures their frequencies through the microphone, then converts them
