When it comes to packing the release build for your shiny new game, you will realize that graphics and audio contribute the most to its final size. Sound effects and music definitely get the first prize in the race to make your download heavier.
As long as you only care about desktop, this should not be a problem. Nowadays, Internet connections are decent enough for people not to mind about moderately big downloads. However, if you plan on releasing for iOS, Android, and/or browsers, you should seriously stop and think about your package size. People are getting progressively more used to instantaneous experiences, but at the moment, not everyone has an unlimited data plan. Even if they do, their speed is usually far from great.
Take a look at how big your package is. In case you think it is over what you deem to be good enough, go through the collection of audio files and try to reduce their weight while ensuring your quality standards.
How?...
