PSP EasyVerb

PSP EasyVerb is a highly efficient algorithmic reverb plugin developed by PSPAudioware designed to deliver complex, professional spatial sounds through a streamlined, low-CPU workflow. An audio engineer’s guide to this plugin focuses on maximizing its “sonically complex but operationally simple” architecture to sit elements perfectly in a mix without wasting CPU resources or getting bogged down in endless parameter tweaking. Core Architecture & Algorithms

The modern iteration (PSP EasyVerb 2) expands on the classic version by organizing its engine into an easily switchable grid of acoustic options:

10 Diverse Algorithms: Features physical spaces (Ambience, Room, Chamber, Club, Hall, Arena, Cathedral), vintage hardware models (Plate, Spring), and creative sound design processing (Reverse).

90 Total Variations: Each of the 10 algorithms can be scaled into Small, Medium, or Large sizes and toggled between three distinct algorithmic tunings: Legacy (the original version 1 sound), Alt1, and Alt2 (richer, modern tonalities).

True Stereo Engine: Supports sample rates up to 96 kHz without summing the input signal before processing, ensuring early reflections maintain accurate spatial positioning. Key Parameter Controls

Instead of overwhelming the engineer with dozens of micro-parameters, EasyVerb distills primary acoustic shaping into five intuitive macro-controls:

Pre-delay: Separates the dry transient from the onset of the reverb. This keeps elements like lead vocals or drums sharp and present rather than buried in the tail.

Decay: Adjusts the overall tail time and size character of the simulated space.

Damp: Controls high-frequency reduction over time. It simulates absorption by softer materials (like wood or fabric) to create a darker, warmer tail that goes deeper than a standard low-pass filter.

Width: Dynamically opens or narrows the stereo image of the reverb return.

Mix & Out: Allows for precise wet/dry balancing (use 100% wet when setting it up on an auxiliary send/return track). Internal Tonal Sculpting (The Built-In EQ)

One of the most critical features for an audio engineer is the integrated 3-Band Semi-Parametric Equalizer. It allows you to clean up the reverb return instantly without needing to insert a separate EQ plugin:

Low-Shelf / High-Pass Filter: Crucial for rolling off low-end frequencies (typically below 200 Hz) to clear out “mud” and low-end rumble.

Parametric Mid-Band: Ideal for dipping harsh frequencies (around 2 kHz–4 kHz) where vocal resonances or harsh guitar frequencies can accumulate in the reverb.

High-Shelf / Low-Pass Filter: Used to tame excessive “splash” or brightness above 6 kHz, ensuring the reverb remains smooth and unnoticeable rather than metallic. Tactical Mixing Guide Audio Source Recommended Setting Engineering Strategy Snare Drum Room Algorithm + Medium Size + 10ms Pre-delay

Creates an authentic acoustic space that emphasizes the groove while the pre-delay preserves the initial stick transient. Lead Vocals Plate or Hall + Alt1 + 25ms Pre-delay

Alt1 provides a lush, modern sheen. A longer pre-delay lets the vocal sit up front, followed by a wide, expensive-sounding tail. Acoustic Guitars Ambience Algorithm + Legacy Tuning

Employs a tight, fixed 1-second decay where the “Time” knob acts as an envelope curve. It glues dry instruments into a cohesive space without washing them out. Synths & SFX Reverse Algorithm + Large Size

Perfect for sound design, creating swelling risers and otherworldly pads that defy natural gravity. Pro-Engineering Summary

PSP EasyVerb shines because its reverb tails do not repeat or loop mechanistically, meaning the space feels organic and blends natively into the mix rather than sounding “grafted on”. Because it is intentionally conservative on CPU usage, engineers frequently use it across dozens of individual tracks simultaneously as a “spot reverb” rather than saving it strictly for shared global aux busses.
