Final answer:
The correct answer is option d) Digital recordings are only available in mono.
Step-by-step explanation:
The main difference between analog recording and digital recording is the way sound is captured and stored. Analog recording involves capturing sound waves in a continuous form, which can vary continuously in amplitude and frequency. In contrast, digital recording captures sound by sampling it at discrete intervals and representing the sound wave in binary form, as a series of zeros and ones.
The key distinction lies in the representation of the sound waves; analog is continuous while digital is discrete, involving a process of quantization where the continuous signals are converted into a discrete digital signal through an analog to digital converter. This conversion usually requires a cut-off value for voltage to determine how to digitize the analog signal.
Digital recordings are highly resistant to noise and degradation over time compared to their analog counterparts. Moreover, digital recordings have a much larger information-storage capacity, allowing for more data to be stored in a smaller physical space. This capacity is exemplified by the fact that an entire encyclopedia can be stored on a single CD, whereas previous analog storage media like vinyl records and audio cassettes had significantly less storage capability.
