From Analog to Digital: The Digital Revolution

The transition from analog to digital technology has been a pivotal shift in modern society, driven by the pursuit of enhanced quality, efficiency, and accessibility. Prominent examples of this transformation include:

• Photography: The shift from film to digital cameras has revolutionized image capture and storage. Digital photography offers superior image quality, instant results, and effortless editing capabilities (Hannavy, 2013).
• Music: The music industry has witnessed a dramatic transition from vinyl records and cassette tapes to digital formats like MP3. This shift enabled higher sound quality, portability, and easier distribution (Morozov, 2011).
• Television: The broadcasting industry has moved from analog to digital signals, resulting in improved picture and sound quality, increased channel capacity, and the introduction of interactive features (Federal Communications Commission, 2009).
• Telephony: The traditional analog phone system has been replaced by digital networks, leading to clearer voice quality, higher call capacity, and the integration of data services (ITU, 2008).

A codec, a contraction of "coder-decoder," is a device or software application that compresses data into a format suitable for transmission and then decompresses it for use (ITU-T, 2020). Essentially, codecs bridge the gap between raw data and its practical application. By efficiently compressing data, codecs reduce bandwidth requirements and storage space while maintaining acceptable quality. They are indispensable in various digital technologies, including video conferencing, streaming media, and digital audio broadcasting.
