More advanced utilities, often called "bit-copiers," do not try to understand the data. Instead, they sample the incoming audio signal at a very high frequency and replicate the exact timings on the output. This is crucial for copying tapes with "turbo loaders" or non-standard speeds that the default Spectrum ROM cannot read. Popular ZX Copy Software & Utilities
Understanding how these utilities work involves diving into the machine's unique audio-to-data conversion and the clever technical workarounds developed to bypass copy protection. How ZX Spectrum Copy Software Works zx copy software work
Software is encoded as a sequence of pulses. A "zero" is represented by a pulse of roughly 244 microseconds, while a "one" is roughly twice as long. More advanced utilities, often called "bit-copiers," do not
