About this plugin
AudioThing's SX1500 is a surgical dynamics processor that approaches compression from first principles, prioritizing transparency and musical control over transparent gain reduction. The plugin models analog circuitry with precision, delivering the subtle colorization typical of vintage British and American compressors without introducing artifacts or latency issues that plague less thoughtful implementations.
The core strength lies in its three-mode topology. The feed-forward design excels at catching transients with minimal overshoot, making it suitable for drums and bass work where timing precision matters. The feedback path introduces the gentle coloration and lag characteristic of transformers and tube stages, ideal for vocal chains and mix bus applications. A hybrid mode bridges these approaches, offering flexible compromise that adapts to material rather than forcing compromise.

What separates SX1500 from crowded competition is the lookahead function coupled with makeup gain automation. Rather than sacrificing attack speed for musical compression, the lookahead mechanism allows faster response times without the audible pumping that betrays heavy compression. The makeup gain curve options accommodate everything from linear compensation to vintage-style soft knee behavior.
The metering is exceptionally clear, displaying gain reduction, input level, and envelope activity simultaneously. This transparency aids in making informed decisions during mixing rather than relying on ear fatigue and guesswork.
SX1500 performs exceptionally on sources requiring nuanced control - vocals, acoustic instruments, and stereo sources benefit most. It's equally effective as a mastering tool where transparency is paramount. Among comparable processors in its price range, it represents a mature, well-engineered approach that rewards careful parameter adjustment with genuinely musical results.
