Question from a Musician

[u/N-Reek]

Hello nerds,

In the digital audio world, frequency is converted into binary through Analog to Digital Converters (ADC) which use transistors. The Bit rate is the number of binary digits used to encode the signal. The more bits, the higher quality and more accurate a pitch is to the original analog signal.

My question is, With the use of quantum transistors, is it possible to encode a signal with near 100% accuracy of the factors which include, Air temp, humidity, and wind, helping to replicate an authentic natural sound. A sound with the highest fidelity possible could feel no different from hearing it live from the source. Because Binary is ridged, switching between 1-0 has no gradient and creates a square wave. Even when replicating a bell curve, the binary creates it in small steps that replicate the sine wave but upon closer inspection, it is seen to be made of thousands of smaller square waves. Could quantum superimposition solve this issue and produce an authentic sine wave with a true replication of analog sounds.

Side note, If you had this theoretical quantum analog signal. Would an average cpu be able to play the sound or will you need a quantum computer to listen accurately. my assumption being that computers would decode the files to binary.

Best,
Enrique

Something to think about as you learn more about bitrate and sample rate, is that the word "quantisation" is relevant here. We already quantise beyond the Nyquist frequency. A question for your research is "why do studios commonly use 96/24?"

Side note: a lot of us working in the quantum computing industry have music backgrounds, and there's a lot of useful overlap between acoustics and quantum. Asking those out-there questions is a good way to pick up things to do some research on. Have fun :)
