More detailed explanation of --step and --length flags in stream

[BlackBatA8T]

Hi, I am trying to get whisper.cpp to work on a Raspberry Pi 4B and its going well. However when I use ./stream it cuts off bits of text and takes a while to load. using the -sa flag shows that the audio gets cut off. changing the --step and --length helps but I feel that to get the best settings I would need to better understand what those two flags do. I have read the explanation from using -h but its still unclear.
