  • My novice take: the waveforms on the right are sufficient to recreate analog stereo.

    Digital audio signals are fundamentally represented by a series of numbers with a frequency corresponding to a fixed sample rate. For example: 16-bit unsigned integers at 44.1kHz. Each number is a sample and represents only a magnitude/intensity in time, forming a time domain waveform. Tones and pitches, and everything else one can hear are represented by these numbers in varying arrangements. Check out the waveform for a sine or triangle tone: the waveforms literally depict those shapes.

    The optical analog waveform is encoding the same information as the sampled digital one described above. I’m not sure of the mechanism by which an optical system translates the analog waveform into sound, however.

    While I’m sure there are plenty of boomers with shitty opinions, it’s the same situation for millennials. Who do we think is bolstering crypto and Fintech?

    Keep in mind we’re fighting a class war, not a generational war.
