The speaker recorded themselves singing Do, Re, Mi, Fa, So on a basic school laptop microphone and explains that zooming in reveals the waveform split into two stereo channels. By examining deep zoom levels, they show discrete sample points represented as decibel values (including fractions like 0.5 and 1 decibel). They note that samples are played 44,100 times per second, creating a smooth wave to the ear, and that the gaps between samples represent the sample interval.</description></oembed>
