You have a broad royalty-free license for every sample that you download from Splice Sounds. This means you can use, reuse, remix, and otherwise modify and mangle downloaded samples in any of your productions, including commercial projects, from block bangers to movie scores to voicemails.
This excerpt from our Terms of Service sets the tempo:
Sounds are licensed, not sold, to you. We grant you a non-exclusive, non-transferable, perpetual right to use Sounds you obtain through Splice Sounds in combination with other sounds in music productions to create new recordings. This means that you may modify, reproduce, publicly perform, distribute, transmit, communicate to the public and otherwise use Sounds, including for commercial purposes. However, you may not (a) use the Sounds in isolation as sound effects, loops, or as source material for any other form of sample (even if you modify the Sounds), (b) use Sounds in a manner competitive to Company or its licensors, (c), sell, loan, share, lend, broadcast, rent, lease, assign, distribute, or transfer all of the Sounds to a third party except as incorporated into a new music production; or (d) redistribute Sounds in new sample packs. Additionally, for clarity, you may not use the name, image, or likeness of the artist associated with a Sound in any way without that artist’s express written permission.
