The software looked for the exact moment the electrical signal from the tape tape changed from high to low, or low to high (an "edge").
Some copy utilities worked via hardware add-ons (like the Multiface 1 ). Users would load a protected game normally. Right before the game started, they pressed a physical button on the hardware device. This froze the Spectrum’s CPU and transferred control to the copy software, allowing the user to dump the completely decrypted game straight from RAM onto a fresh tape with a standard, unprotected header.

The computer converted digital 1s and 0s into audible frequencies. When saving a program, the Spectrum outputted specific tones: a long "pilot" tone to prepare the computer for incoming data, followed by rapid data pulses. A high-frequency pulse typically represented a binary '1', while a lower frequency represented a '0'. Because tape recorders were prone to speed variations and signal degradation, reading this audio data back into the computer's memory was a fragile process. The Standard ROM Loader and Its Limitations zx copy software work
Standard loading was slow (roughly 1500 baud). Many copiers included "turbo" features to save games in a faster format, speeding up future load times.
Known for their efficiency.
A known issue with zxfer involves the objsetid property being marked as read-only, causing the creation of destination filesystems to fail. The solution is to add objsetid to the list of readonly properties in the script configuration.

If you are looking at specific vintage utilities, I can break down the exact loading instructions for your system. If you want, let me know:
The copy program loaded itself into the highest or lowest lines of the Spectrum’s RAM. It then redirected the computer's cursor to wait for input. Right before the game started, they pressed a
