I'm a Sound Designer that enjoys uploading and recording newly made and altered/unaltered sounds. Freesound has helped me with hundreds of projects and as such I have decided to make all of my sounds public domain.
Feel free to use all/any of my sounds in your projects for FREE!!! Re-selling of my sounds (outside of projects) is however illegal.
Also feel free to leave a link to your projects in the comments section. Would love to see (hear) how you used my sounds. :D
