CapSun ProAudio is a boutique sample creation and sound design company based in Brighton, UK. Co-founded in 2015 by producer Jay Pulman (known professionally as Capsun) and Matt Borzoni, the company brings together an international team of producers, musicians, and sound designers who create royalty-free sample packs, drum kits, original compositions, and custom synth presets.

The label is known for its work across electronic genres including trap, hip-hop, grime, house, and bass music. Its catalog of sample packs is distributed primarily through Splice, which acquired CapSun ProAudio in 2018. Pulman went on to serve as Creative Director at Splice Sounds, and the team also operates the vocal-focused sister label 91Vocals.

Beyond their own releases, CapSun ProAudio has produced sound content and presets for major music technology companies, with clients including Native Instruments, Novation, Akai, Propellerhead/Reason Studios, Bitwig, Loopmasters, Plugin Boutique, Producertech, and Retronyms.

CapSun ProAudio has 30 products cataloged on Equipboard, including Chill Trap, Artist Series, and FX.
