PSP Neon HR — Free Download

Purpose

PSP Neon HR is a fully featured linear phase equalizer plug-in designed for mastering and other critical audio applications. It offers eight bands of equalization, each assignable to one of seven filter types, providing flexible tonal shaping. The plug-in uses frequency-domain fast convolution based linear phase algorithms for a balance between CPU efficiency and phase accuracy.

For CPU-critical tasks, you can toggle off the linear phase mode to use the minimum phase error Infinite Impulse Response (IIR) mode, which leverages the same analog-modeled filters with lower processing demands. This dual-mode capability makes it adaptable to various workflow needs without sacrificing the core equalization power.

Key Capabilities

Version 2 of PSP Neon HR retains compatibility with version 1, ensuring that existing sessions and presets load seamlessly. It offers three spectral resolution levels: high resolution and max resolution modes for demanding mastering tasks, alongside the standard resolution found in the STD edition. The HR variant is engineered for exceptional fidelity, especially when processing complex material.

Independent processing and control of each stereo channel, along with stereo and mid-side operation, give you precise control over the stereo image. Oversampling ensures clean processing at high sample rates up to 192kHz, while PSP’s proprietary FAT mode enhances internal precision. A real-time third-octave spectrum analyzer with adjustable parameters supports visual monitoring, and frequency-hunting and overtone-hunting accelerators help identify problematic frequencies quickly.

Workflow

PSP Neon HR emphasizes an intuitive, user-friendly interface designed for efficient workflow. The response plot auto-zooms to focus on recent edits, and each EQ band can be soloed for isolated listening. The spectrum analyzer not only displays the audio spectrum but also aids in finding resonant or problematic frequencies, with customizable parameters to suit different sources.

The combination of high-resolution modes, mid-side capability, and the option to switch from linear phase to minimum phase processing provides flexibility in various situations. Whether you need transparent correction or more characterful filtering, the interface supports quick adjustments, making it a reliable choice for professional mastering suites.

Practical Applications

PSP Neon HR suits mastering engineers who require transparent, phase-accurate equalization for final mixes. The mid-side processing allows independent EQ of mid and side channels to refine stereo width, while the spectrum analyzer and frequency-hunting tools streamline corrective and creative adjustments. Its high-resolution modes are ideal for surgical cuts or gentle boosts on full mixes without introducing phase artifacts.

When working on demanding material, such as dense orchestral recordings or complex pop productions, the linear phase mode preserves the integrity of transient information. For less critical tasks, switching to minimum phase mode reduces CPU load while retaining the same filter character. The compatibility with version 1 ensures you can recall previous projects with confidence.
