Nectar 4 Standard is a comprehensive vocal mixing suite with AI-assisted tools for layering harmonies, creating backup singers, and tone-matching references, plus dynamic EQ and pitch correction.

Purpose and Core Concept
Nectar 4 Standard is a dedicated vocal mixing and production tool designed to streamline the entire vocal chain. It combines traditional processors with AI-driven modules to help you achieve polished results quickly. The suite covers everything from basic equalization and dynamics to advanced harmonic layering and reference matching.
The core workflow centers on the Vocal Assistant, which uses machine learning to analyze your vocal and create a custom preset tailored to your mix. You can choose from built-in targets or import your own reference track to guide the sound. This makes it suitable for both beginners seeking guidance and experienced engineers wanting a fast starting point.
Key Capabilities and Modules
The Voices Module allows you to generate automatic harmony layers based on your lead vocal. You can select from a variety of preset harmony styles, enable MIDI mode for precise note control, and adjust the number of voices and their range. The Mixer View gives you individual control over each voice’s level and position.
The Backer Module creates artificial background singers from your main vocal. You can shift the vocal into different style presets or import your own acapella for a custom sound. Tone, Pitch, and Formant controls let you blend these backing vocals behind your lead, and automation allows for evolving arrangements.
Workflow Integration and Processing
Nectar 4 Standard integrates with iZotope’s Audiolens for reference-based mixing. You can capture audio from any source, separate the vocal, and use that tone as a target for the Vocal Assistant. This creates a clear starting point for matching a reference sound in your session.
The included Dynamic EQ features a Follow EQ mode that tracks the pitch of the vocal, automatically adjusting frequency nodes to tame resonances and shape tone. Two such EQs are provided, each with adaptive nodes and pitch tracking. This reduces manual editing and helps maintain a clear, controlled vocal sound.
Practical Applications and Extras
This tool is well-suited for music production, demo creation, and creative sound design. You can quickly add harmonies to a chorus, generate backing vocals for a full arrangement, or experiment with different vocal styles. The Vocal Assistant’s unmasking feature helps your vocal sit clearly in a busy mix.
The suite also includes Melodyne 5 essential for detailed pitch and time correction, plus iZotope Relay for inter-plugin communication. Hundreds of presets cover music and dialogue scenarios. The combination of AI assistance and manual controls makes it flexible for both rapid workflows and detailed tweaking.
