A Sound Effect is giving away the Krypton sound effects library by SmartsoundFX for free to all current and new subscribers of its Audio Jobs newsletter. The offer launched today and expires in 72 hours, so act fast if you need some free cinematic sounds.
The Audio Jobs newsletter has been running for seven years, highlighting 20 new sound-related job openings every week. So, regardless of the freebie, it’s worth checking out if you’re interested in a job that has a thing or two to do with sound.
But anyway, back to the freebie.
To grab Krypton for free, visit the giveaway page, add the library to your cart, then subscribe to the newsletter (or enter your existing email if you already subscribe) to unlock a 100% discount code. Apply the code in your cart and check out for $0.
Krypton normally sells for $65 and contains 300 cinematic sound effects recorded at 24-bit / 48 kHz, totaling over 3 GB of content. The library covers dark and light atmospheres, hits, braams, risers, glitches, drones, booms, and whooshes.
If you work on film, trailers, or any other cinematic projects, this is an easy addition to your sound collection. But cinematic SFX packs like this one are also useful for other stuff, not just film and video work.
If you produce electronic music or any genre that benefits from dramatic sound design, atmospheres, risers, booms, and whooshes can add a lot of impact to intros, breakdowns, and transitions. These types of SFX work well across EDM, trap, and plenty of other styles.
The library was developed in cooperation with Vamify and is delivered as an instant digital download. The license is royalty-free, and you can select the number of users on checkout.
If you’re looking for more cinematic sounds after picking up Krypton, check out the free Cinematic Sound Effects library by Flame Sound, which also includes braams, risers, booms, glitches, whooshes, and similar material (there’s also a free pack for Riser Sound Effects).
