What is generation loss?

Generation loss refers to the degradation of quality that occurs when an analog recording is copied or re-recorded multiple times. Each subsequent copy of the original recording results in a loss of fidelity and detail, leading to a decline in overall sound or image quality. This can manifest as a loss of clarity, increased noise, distortion, or other artifacts.

Generation loss is more common in older analog formats such as cassette tapes, VHS tapes, and film reels, as each copy of the original recording introduces imperfections that accumulate over time. However, digital formats are not immune to generation loss, as compression and re-encoding can also degrade the quality of the original file.

Despite advancements in technology, generation loss can still be an issue when making multiple copies of a recording, which is important to keep in mind when preserving or sharing media. Strategies to minimize generation loss include making high-quality copies, using lossless formats, and avoiding excessive re-recording.
