The Dutch company Sound Performance Lab (SPL) has been producing professional audio equipment for radio, film, music, multimedia and hi-fi for more than 30 years. One of the milestones in the company's history is the patented Vitalize sound optimisation, the invention of level-independent envelope processing, the development of the auto-dynamic de-esser with S-sound reduction via phase cancellation, the first discrete 5.1 surround microphone system (Atmos 5.1) 120V operational amplifier and the invention of the phonitor matrix for loudspeaker-equivalent hearing and mixing over headphones. Sound Performance Lab stands for innovative products based on the classical musical qualities of analog technology, which are also the starting point for digital audio products.
