What Split Audio is for
A two-hour recording is awkward everywhere: too long to upload, too long to find anything in, too long to send. This cuts it into parts either at a fixed length or at the gaps between speakers, and does it by copying, so a long tape splits in seconds rather than being re-encoded end to end.

Questions
Should I split by length or at the gaps?
By length when something has a limit — an upload cap or a platform maximum. At the gaps when the recording has structure worth keeping: separate takes, tracks off a tape, or speakers taking turns.
Where exactly does it cut when splitting at gaps?
In the middle of each silence. Cutting where the pause ends leaves every part with its trailing silence attached; cutting where it starts moves that silence to the front of the next part. Halfway gives both sides a little air.
It found no gaps. What now?
Either the recording has no pauses long enough, or the threshold is wrong. Shorten the gap length, or raise the threshold so quieter passages count as silence — a noisy room floor can sit well above the default.
Does splitting reduce the quality?
No. The parts are copied out of the original, so each one is exactly the audio it was.
