Free SFX
One of the largest and most popular community-driven sound libraries. Thousands of user-uploaded recordings covering every sound imaginable.
The largest community-driven Creative Commons sound library on the internet. Over 720,000 sounds uploaded by users worldwide. Everything from field recordings to synthesized sounds to foley to musical samples. All under Creative Commons licenses (CC0, CC-BY, CC-BY-NC).
The power of Freesound is the sheer volume and diversity. Need a specific sound? Someone has probably recorded it and uploaded it here. The search works well, you can filter by license type, and the community adds new sounds daily. Quality ranges from amateur phone recordings to professional field recording work.
Created by the Music Technology Group at Pompeu Fabra University. Been running since 2005.
Massive resource for game audio. The CC0 filter gives you sounds with zero attribution requirements — use them commercially without any restrictions. For CC-BY sounds, you just need to credit the author. The volume means you can find almost any sound you need, but budget time for auditioning since quality varies widely.
