Spazial is a dynamic audio processor plug-in designed to enhance stereo imaging by encoding and decoding stereo signals into mid/side (M/S) formats. This functionality allows precise control over the stereo field, enabling users to widen or manipulate the spatial characteristics of their audio in creative ways. Its ability to seamlessly convert between stereo and M/S signals makes it a valuable tool for mixing and mastering tasks.

The plug-in offers five operational modes, including internal processing, send mid, send side, Spazial mode, and decoder mode, each providing distinct approaches to signal manipulation. Users can adjust encoded signals through five dedicated controls or route pure encoded signals directly to the output, offering flexibility in how the stereo field is shaped. Additional features include a high-pass filter to refine the frequency response and a unique vibrato control to add movement and modulation to the stereo image.

Available as a VST plug-in for Windows, Spazial is offered as free donationware, making it accessible to producers and engineers seeking advanced stereo processing tools without cost barriers. Its intuitive interface and comprehensive feature set make it suitable for a range of audio production scenarios, from subtle stereo enhancement to more pronounced spatial effects.
