Focus Bundle — Free Download
A trio of stereo enhancement tools for music and post production, offering natural widening, bass focusing, and precise stereo placement with high mono compatibility.
Purpose and Core Tools
The Focus Bundle by Nugen Audio combines three plug-ins aimed at improving the stereo field of audio material. The core tools are Stereoizer, Monofilter, and Stereoplacer, each addressing a different aspect of stereo image control. The bundle is designed to provide rapid access to professional-level enhancement while preserving the original character of the sound.
All three plug-ins emphasize high mono compatibility, using unique algorithms to avoid phase issues, reverb, or delay-like artifacts. This makes them suitable for situations where mono playback is common, such as broadcast or club systems. The tools work across the full frequency range, offering flexible control over the stereo panorama.
Key Capabilities of Each Tool
Stereoizer provides natural widening or reduction of the stereo image, adding depth and space without artificial effects like chorusing or reverb. It can be used on mono or stereo recordings to increase perceived width while keeping the source intact. The plug-in also features frequency-banded control, allowing users to target specific spectral regions for enhancement.
Monofilter focuses on bass management by anchoring low frequencies in the center of the mix. This helps to eliminate muddiness and phase inconsistencies that can weaken the low end. It aligns and balances low frequencies for a tighter, more defined bass, and is particularly useful for improving playback on systems with separate low-frequency handling, such as club PAs or 2.1 setups.
Workflow and Control Features
Stereoplacer offers precise control over the stereo position of specific frequency bands. Users can solo frequencies to focus on them, then adjust their placement in the stereo field without affecting other regions. This is useful for correcting poor recordings, reconstructing a mono image, or repositioning complex audio elements.
The plug-ins feature dynamic visual feedback to aid in fine-tuning adjustments. Each tool includes parametric balancing controls for detailed tweaking. The combination of these tools allows for a complete stereo correction workflow, from initial widening or narrowing to bass alignment and precise placement, all while maintaining the original sound character.
Practical Applications
In music production, the Focus Bundle can be used to enhance and fix mixes in various ways. For example, Monofilter can be applied to synth lines to correct low-end smear caused by integrated effects, or on reverb returns to tighten low frequencies while preserving spatial sense. Stereoizer can widen sounds needing more polish, and Stereoplacer can add life to mono sources or adjust samples when the original mix is unavailable.
For post and broadcast, the suite proves valuable when re-recording is not possible. Monofilter helps ensure clear low-end power distribution across TV, radio, and internet. Stereoplacer can fix or reposition specific elements, or follow on-screen action by automating stereo position—useful for boom microphones. Stereoizer can subtly enhance ambiences to open space for dialogue or inject life into mono recordings.
