Fuse Audio Labs


About Fuse Audio Labs

Fuse Audio Labs was founded in 2017 by Reimund Dratwa who has an experience of many years working for different big names in the audio business during which he created dozens of renowned analog modeling titles. It was initially intended as an engineering company that works for various partners, but it soon became apparent that it could also serve as a channel for our own ideas and allow us to pursue our vision. The same expertise that went into the aforementioned products goes into everything that we create.

Our software has to pass a strict and extensive testing cycle to ensure the stability and reliability required for realtime audio DSP. All our plugin titles can be installed and tested for a trial period of 14 days without any restrictions. Our entire line of products is fully compatible with the VST2, VST3, AAX and AudioUnits plugin formats and runs in 32 and 64 bits on Mac OS and Windows. Selected processors will be provided in the inter-app audio format for mobile iOS devices and will be made available via Apple's App Store soon.
