How to find a good sound effect

[Jim Scott]

How about an online search for “free sound effects”?

[Todd Perchert]

Good is relative as is many. There are online sites, some paid, some free with registration – like https://www.freesfx.co.uk/
If you download Media Composer First, they had a free 300 sfx bundle you can download as well. You can Google for others, but be prepared for slim pickens. Best ones are paid.

Free? Hmmm, well expect to spend a LOT of time doing internet searches I suppose. When ya get tired of that & willing to shell out a bit, you might take a look/listen to Mr. Horse’s stuff:

Or you can do what I usually do: Have/find a long time friend & poker buddy who’s a multi acadamy award winning foley editor.
