2nd Sense Audio is a Beijing, China-based audio software developer focused on creating tools for electronic music production and audio editing. The company's flagship product is Wiggle, a dynamic waveshaping synthesizer plugin that features four color-coded FM operators, an FM matrix, two multimode filters, and six built-in effects. Wiggle's distinguishing feature is its snapshot morphing system, which allows users to capture up to four parameter snapshots and smoothly morph between them. The plugin also includes a step sequencer with MIDI drag-and-drop export. Wiggle is available in VST, AU, AAX, and standalone formats for Windows and Mac.

Beyond Wiggle, 2nd Sense Audio developed ReSample, a standalone audio editor with vocal removal, time stretching, pitch shifting, noise reduction, and support for over 20 built-in processors. The company also released the 2S Plugins Bundle, a collection of mixing and mastering utilities including 2S Mixing Analyzer (for detecting frequency collisions across multiple tracks), 2S AlgoReverb (modeled after 1980s hardware reverb units), 2S Engineering Filter, 2S Vocal Remover, and the free 2S Equalizer, a seven-band parametric EQ with a real-time spectrum analyzer.
