Commercial giants like iTunes, Windows Media Player, and later Spotify focused on convenience and streaming. They didn't care about the 16th bit of the 3rd second of the 2nd track. But the community of audiophiles, data hoarders, and music librarians never abandoned EAC. They wrote detailed setup guides, created databases of drive offsets, and shared their perfect log files as proof of their digital virtue.
A CD is not a hard drive. Hard drives have error-checking built-in; if a sector is hard to read, the drive re-reads it until it gets the right answer. Audio CDs, however, were designed for the smooth, continuous playback of a stereo system. They used a simpler, real-time error correction scheme called CIRC (Cross-Interleaved Reed-Solomon Code). This could fix small scratches or dust, but if a section was too damaged, the drive wouldn’t try again—it would simply guess what the missing data should be, a process called . It would "conceal" the error by averaging the sound of the good samples before and after the bad one.
The story of Exact Audio Copy is not a story of sleek marketing or a disruptive startup. It is a proper story of a simple, stubborn question: "What if we just read it again, and again, and again until we got it right?"
