lkjb QRange
Key Features
- Provides 12 sortable EQ bands for building detailed corrective or tonal curves in one plug-in window.
- Lets each band operate as a peak, shelf, or cut filter, with 12, 24, and 48 dB/octave options for cut filters.
- Applies stereo, left, right, mid, or side routing independently per band for targeted imaging and balance work.
- Offers linear-phase processing without pre-ringing alongside a latency-free minimal-phase mode for faster sessions.
- Includes a pre/post analyzer that follows the band-routing choices and has an adjustable display range.
- Uses Gain Match to compare input and output short-term EBU loudness while audio is playing.
- Supports a resizable interface plus saved default EQ states and interface sizes for new instances.
Description
lkjb QRange is a 12-band IIR linear-phase EQ for detailed tonal shaping in mixing and mastering. It combines peak, shelf, and high- or low-cut filtering with per-band stereo, left, right, mid, and side routing, so one instance can handle corrective work and focused stereo adjustments.
The analyzer can show the signal before or after EQ using the same routing choices as the bands. Gain Match compares short-term EBU loudness while audio is playing, which makes it easier to judge an EQ move without being misled by level changes.
QRange also offers a selectable latency setting for its linear-phase mode and a latency-free minimal-phase mode when a delay-sensitive session needs a faster option. The resizable interface and default-state controls keep repeated EQ tasks practical without turning the plug-in into a fixed mastering-only tool.
It suits clean, deliberate shaping rather than analog-style coloration. KVR reviewers specifically highlight the broad routing options, zero-latency mode, and usefulness for detailed headphone-correction or mastering-style curves, while one older macOS review notes that high latency settings can be demanding in some sessions.
Frequently Asked Questions
What type of EQ is lkjb QRange?
QRange is an IIR linear-phase EQ with 12 sortable bands. Its bands can be used as peak, shelf, or cut filters, and each can be routed to stereo, left, right, mid, or side processing.
Can QRange run without added latency?
Yes. The official page lists a latency-free minimal-phase mode in addition to its adjustable-latency linear-phase processing, so you can choose the mode that fits the session.
How does QRange help with level-matched EQ decisions?
Its Gain Match feature measures short-term EBU loudness at the input and output and adjusts the gain while audio is playing. That is useful when comparing tonal changes without a simple loudness increase biasing the result.
Which plug-in formats and operating systems are listed for QRange?
The current KVR product listing identifies VST, VST3, and AU support for Windows and macOS. It lists Windows 7 or higher and macOS 10.7 or higher.
