Why do my sound effects click when they play in Unity?
A click means the waveform does not start at zero. How to find it, the 5 ms fix, and why a level meter never shows it.
Straight answers on game audio: licensing AI-generated sound effects, the format to ship to Unity and Unreal, how much headroom to leave, and why clips click. Written from the work of preparing and shipping this catalogue, so the numbers in them are measured rather than repeated.

Yes, if the plan you generated on grants commercial rights. What Unity, itch.io, Fab and Steam each require you to declare.
Ship uncompressed WAV and let the engine compress once. Unity and Unreal re-encode on import, so a compressed source is compressed twice.
A file peaking at 0 dBFS can clip after the engine re-encodes it. Why -1.5 dBTP, what true peak measures, and why per-file normalisation hurts.
Each one answers a question that comes up repeatedly from people buying or building game audio, and each is written from something that actually happened here: an Asset Store rejection, an audit of 150 shipped files, a levelling pass that moved a peak back over spec. Where a number appears it was measured on real files.
There are 251 free sounds if you would rather test the conclusions than read them.
