Overview

SPL and Brainworx, the masters of analog modeling, are back with the plugin of SPL BiG. The 2024 TEC Signal Processing Award-winner, this studio stereo expander won praise from the pros for its huge sound and ingenious design. BiG is fun to use. BiG is distinct. BiG offers new imaginative avenues for sound shaping. Make your mixes sound massive with zero phase issues.

Go BiG or go home

Stereo image enhancement is an important tool for winning the loudness wars and bringing depth and immediacy to tracks. But phase issues have always limited the pros and put off the less experienced. SPL BiG solves these issues and lets you do even more. It processes stereo input with a unique filtering network that prevents phase shifts, cancellations, and unwanted artifacts when summing to mono. Now everyone can benefit from the bigness. 

Push your stereo image into new dimensions

SPL BiG is a powerful stereo image processor that offers exceptional control over stereo width and character. Enhance individual tracks by pushing them wider or bringing them to the front of the sonic stage. Add analog tone for fresh, bold mixes. Use it subtly or aggressively to make keyboards, strings, vocals or full mixes as BiG as you need.

Depth and bigness with just five controls 

With its three knobs and two switches, SPL BiG makes radical stereo image enhancement simple, satisfying and free of phase issues.  

Range Control
Adjusts the filter frequency for precise control over the processed range.

Stage Control
Manipulates the slope and bandwidth. Make key elements of your mix feel more present or push them back to shift focus and create a greater sense of depth.

Bigness Control
Bring the “Bigness”. This unique blend knob mixes processed and original audio with SPL's proprietary combining method, delivering dynamic control over stereo expansion and balance.

Simple on the surface but sophisticated at the core

SPL BiG utilizes a unique stereo processing technique that’s distinct from M/S processing. This is how it enhances your stereo image without introducing phase issues or cancellation to individual tracks, stems and mixes, even when summed to mono.  

AirBass EQ plus plugin-exclusive features 

SPL BiG also features a bass boost function, using a passive filter inspired by the AirBass circuit in the SPL IRON Mastering Compressor, to enhance your tracks with low-end warmth. The SPL BiG offers plugin-exclusive features including panorama controls, automatic gain compensation, M/S metering, and Mid/Side solo functionality.
