SPL has been developing and manufacturing analog and digital audio gear for the music, film, multimedia, and broadcasting industries since 1984. SPL products are respected worldwide for their innovative approach and user-friendliness, but most of all for their outstanding performance.

Among SPL's most celebrated developments are the patented Vitalizer® sound-optimization processing, the first-ever level-independent dynamic processor known as the Transient Designer, the 5.1 microphone system Atmos, as well as compact monitor controllers and channel strips.

The development of the SUPRA op amps by SPL allowed analog signal processing to outperform the best digital processing in terms of quality. These op amps, which make use of the unsurpassed 120-volt technology, were first used on the MMC mastering console. Ever since, the 120-volt technology has become a quality trademark of SPL products, including the Phonitor headphone amplifiers. More recently, SPL stormed the USB and MADI audio interface market with the introduction of the Crimson and Madison interfaces.

Its collaboration with German company Brainworx resulted in the Analog Code plugins, which translate to the digital realm the same quality expected from all SPL products. This relationship has led SPL to become a member of the Plugin Alliance.

With the Car Vitalizer app, SPL entered the smartphone market and redefined the concept of audio enhancement inside a car — without the need of any additional hardware or expertise. This know-how has allowed SPL to license its technology to major players in the auto industry.

  This plugin delivers vacuum tube saturation for days, from subtle warmth to dirty grunge, it sounds fantastic on digitally harsh sounds, and absolutely KILLS on vocals and brassy material.

  SPL Transient Designer does exactly what I hoped it would do and lives up to its hardware equivalents famous status . Super useful on the drum buss for increasing bite/impact  , and a great way to quickly tame synth parts that have too much attack.

  Sound is awesome, the original plugin version goes into a lot of my productions. PLUS version: I love the new parallel mix feature. I can crank up attack or sustain and just blend in the amount I like. The built-in limiter is a great tool to tame the added transients.
