Best Sites to Download Sound Effects From Legally
You can download sound effects legally by choosing options that are available publicly and don’t have a license, options that are available under Creative Commons (CC) licenses, or royalty-free options.
There are some sites where you can download unlicensed sound effects for free. Typically, these are not particularly high quality.
Other sound effects are under a CC license, which often do not cost to use as long as you credit the creator.
Sound effects that are professionally created can be obtained through a royalty-free license. You can download and use these legally with a subscription to a service or for a one-time fee.
Most sound effects are protected through some form of license, and you will need to obtain the license to download them for legal use in your project.
