What Soundiron is
Soundiron develops virtual instruments and sample libraries for songwriters, composers and sound designers working in music production and media composition. Its catalog spans deeply sampled instruments and sound effects, with most products made for Native Instruments Kontakt. Many libraries require the full retail version of Kontakt; some are also offered in Decent Sampler or SFZ, with formats listed on each product page. Kontakt libraries run in compatible VST, AU, RTAS or AAX host sequencers. The free Rainsong library includes rain recordings, one-shots, 58 ambience patches and 20 sound-designed FX and ambient presets. Other listed examples include Iron Pack Bundle at $39 one-time and Hyperion Strings Micro at $49 one-time. Purchased sounds may be used in finished commercial and noncommercial productions, but raw or unmixed content cannot be redistributed. Products arrive electronically, with an installer and download code sent by email. Soundiron serves creators from beginners to professionals across film, television, advertising, games and recording.
