What is the difference in sp spp lp ep slp ho in record mode?

In record mode, "sp" typically refers to standard play, while "spp" indicates a special play mode. "lp" stands for long play, which allows for extended recording time at the expense of quality. "ep" or extended play offers a compromise between quality and recording duration. "slp" is super long play, maximizing recording time but significantly lowering quality, whereas "ho" generally refers to high-output modes that prioritize quality over duration.
