I'm in the process of building my own library of field recordings and sounds. I've decided to let most of them loose on my Freesound.org page as a way of giving back to the community there. All sound will be on a Creative Commons license and some of them will be available for commercial projects. Right now there are only a few recordings there but I have quite a few that are waiting on moderators to accept. I'll be adding more and more on a consistent basis.
If you find this sort of project useful to you, please check out my Patreon page and consider pledging your support. Those that do will receive higher quality versions of the sound files that I'm uploading as well as some other benefits. If you need custom sound design done, please visit my website at http://www.pureshift.com. While I am also a composer and a voice actor, I have a passion for recording all the interesting sounds that the world has to offer. My goal is to share that passion with as many people as possible. Please let me know if you have any questions!
