iZotope Relay is a utility plugin designed to simplify and streamline mixing workflows, especially when used in conjunction with other iZotope plugins like Neutron, Nectar, and VocalSynth. It offers a quick way to adjust gain, pan, stereo width, and filter parameters, and its main strength lies in enabling automated processes for mixing, unmasking, and other tasks.

Here's a more detailed look at what iZotope Relay offers:

• Simplified Mixing: Relay acts as a central hub for adjusting basic mixing parameters like gain, pan, stereo width, and filter parameters directly on individual tracks or busses.
• Automated Processes: When used with other iZotope plugins (Neutron, Nectar, VocalSynth), Relay enables automatic mixing, unmasking, and other tasks by communicating with those plugins.
• Visual Mixer Integration: With Relay on your tracks or busses, you can open Visual Mixer (included with Neutron 4 Advanced) and adjust pan, gain, and width directly within the Visual Mixer plug-in, simplifying your mixing workflow.
• Intelligibility Measurement: Relay can communicate with Insight 2's Intelligibility Meter, allowing you to measure the relative intelligibility of your vocals and visualize how they will be heard in different listening environments.
• Unmasking with Nectar: Relay works with Nectar's Unmask mode to remove masking frequencies from vocal tracks, improving clarity and preventing unwanted interference
