SOUND4 processing engines function as libraries, serving as the main processing components in all virtualized versions. These libraries are natively used to integrate our virtualized products as third-party solutions for software editors, ISPs, streaming companies, and broadcasting companies. Naturally, several of our esteemed manufacturing partners also recognize the immense potential of integrating SOUND4 products into their own offerings…
These libraries are intended for advanced users. Help files are integrated with all versions to support SOUND4 processing engine integrations.
