Relab Sonsig ACE is a versatile dimensional expander plug-in with a dual-engine, multi-voice design. It offers hand-tuned LFOs, COLOR modes, and ENRICH delay processing for creating wide, immersive stereo textures while preserving mono compatibility.
Purpose and Core Design
Sonsig ACE is a modulation plug-in engineered to add width and depth to mixes. Its dual-engine, multi-voice architecture moves beyond basic chorus effects, providing a 12-in-1 dimensional expander that suits various audio sources. The plug-in aims to reduce center-channel congestion and spread sounds naturally across the stereo field.
ACE uses proprietary ACE modulation technology and six hand-tuned, waveshaped LFOs to generate lush movement without muddying the mix. These LFOs remain stable even at extreme settings, minimizing traditional phase issues and sync hassles. This core design supports transparent stereo thickening or complex, swirling textures as needed.
Key Capabilities
A key feature is ENRICH, a delay line design that expands sound while preserving its core character. It eliminates artifacts like comb filtering, allowing pristine depth and a luxurious stereo image at higher settings. The COLOR section injects character directly into the modulation, offering modes such as NATURAL, THICK, and FAT.
Each COLOR mode tailors modulation across frequencies, giving precise control over texture and spatial depth. This lets users shape the feel from soft warmth to edgy bite, avoiding the flat sound of typical chorus effects. The plug-in supports exceptional mono compatibility, ensuring mix integrity across playback formats.
Workflow and Texture Sculpting
In practice, ACE can be inserted on individual tracks or buses. For subtle enhancement, lower LFO rates and ENRICH values create gentle width. For dramatic effects, increase modulation depth and experiment with different COLOR modes to achieve thick, complex textures. The hand-tuned LFOs keep modulation focused, preventing muddiness.
The plug-in is designed for immediate results, allowing engineers to dial in a wide range of dimensional effects without complex routing. The ENRICH parameter can be automated to evolve a sound over time, from narrow to expansive. COLOR modes offer quick tonal shifts, making it easy to match the texture to the mix context.
Practical Applications
Sonsig ACE is suited for mix engineers working on music genres that benefit from rich, immersive stereo fields, such as pop, rock, electronic, and cinematic scores. It can thicken vocals, guitars, synths, or pads, adding depth without sacrificing clarity. The mono compatibility makes it reliable for broadcast or club playback.
It also serves as a creative tool for sound design, generating evolving textures for ambient passages. By combining ENRICH and COLOR, users can craft unique dimensional effects that stand out. The plug-in’s flexibility makes it a valuable addition to any mixing or production setup, offering both corrective and creative applications.
