Team BTCR | 17 March 2026 | 180.46 MB

Real-time equal-loudness Contour Shaping

APU Loudness Contour is a real-time equal-loudness filter that offers precise control over a wide range of perceptual loudness contours, including ISO 226 (2003 & 2023), Fletcher-Munson, K-weighting, A/C-weighting, ECMA-418, and ITU-R 468. Each contour is normalized to 0 dB at 1 kHz and includes a dedicated contour weight parameter, allowing you to scale the frequency response in both positive and negative directions. A weight of 0% results in a flat response, while negative weights invert the contour. ISO 226 and Fletcher-Munson curves support variable reference levels from 20 dB SPL to 120 dB SPL, with smooth interpolation between phon curves.

Loudness Limiter v5.3.1 WiN MAC

Team BTCR | 17 mARCH 2026 | 87.61MB

PLATFORM: AU/VST2/VST3/AAX

The APU Loudness Limiter is a real-time limiter designed to support multiple loudness types simultaneously. The limiter can be configured to use LUFS, True Peak, RMS, and/or Peak loudness types. This allows you to target multiple requirements simultaneously, such as a specific LUFS target and a specific True Peak target. Internally, the ballistics of the limiter are adjusted to accommodate the different loudness type limiter settings.

Bass Focus v1.0.4 WiN

Team R2R | 15 March 2026 | 19.6 MB

Bass Focus is a low frequency enhancer for mixing and mastering. It helps bass to sound fuller, louder and more powerful, on all speaker systems; without sacrificing headroom. And on smaller speakers, it reveals low-end which would otherwise be lost. Helping your music to sound its best, even on mobile phones and portable devices. The plugin can be used as a channel insert to enhance individual instruments, or applied to theentire mix. It can add power to 808s, solidify kick drums, thicken synths and bass guitars, and much more. At the mastering stage, it can improve mix translation and presence, thicken the low-end, and recover headroom in problem mixes with too much sub.

Maximal 3 v3.0.5 WiN

Team R2R | 23 October 2024 | 10.9 MB

PLATFORM: VST2/VST3/AAX(MOD)

Maximal 3 is a true-peak brickwall limiter, soft clipper, and broadcast standard loudness meter. Maximal 3 is a loudness maximiser, designed to limit and maximise your track. Featuring both a true-peak brickwall limiter and a variable shape soft clipper, Maximal 3 can increase the overall loudness of your track, without destroying the sonic quality. The limiter features true-peak lookahead detection, meaning inter-sample peaks will never overshoot and clip. With four different modes, and controls for attack and release, the shape of the limiter can achieve anything from transparent limiting with transient preservation, to warm bus gluing or pumping.

MH CGII v4 MAC

P2P | 25 May 2025 | 10.8MB

CGII: Make it Good & Loud!

CGII is comprised of two uniquely complementary dynamics enhancement sections, a new True Peak Limiting stage, DC blocking and dither with LUFS/true peak metering via spiffy tube filament displays, all operating at up to 16x over-sampling (or none at all – depending on your tastes). The design prioritizes musical integrity and ease of use, with the ability to add effective loudness, weight and definition without diminishing spatial depth and visceral impact the way traditional dynamics processors often do. Use CGII to make your masters loud without losing the clarity, density and heft of the original mix. Even if you are working with a mix that is already loud, you can give it a little extra, without adding unpleasant distortion and without flattening out the material and sucking the life out of the low end. At the same time you can control the true-peak level of the program to ensure that there are no inter-sample overs.

EBusLim v1.10.0 WiN

Team R2R | 22 September 2024 | 7.2 MB

EBusLim is a brickwall peak limiter and loudness maximization AAX, AudioUnit and VST plugin for professional streaming, sound and music production applications. EBusLim implements a single EL-4-based limiter mode originally designed in Elephant mastering limiter plug-in. This mode is suitable for bus, drum bus, master bus and track processing. The design idea behind EBusLim is to produce an extremely easy-to-use yet effective limiter. Since EBusLim only features a single processing mode the processing latency was reduced down to 0.5 milliseconds permitting the use of this limiter as master bus overload protector for both stereo and multi-channel real-time applications.
