Brainworx bx_masterdesk mastering software: features and spec-based rating

The mastering software bx_masterdesk from Brainworx (Plugin Alliance) puts processing modeled on high-end analog mastering gear into a single plug-in. It is designed to make a master in a short time with a few knobs and presets (settings prepared in advance).

Mastering software finishes a completed mix to a loudness and tonal balance that suits streaming and CD.

In this article we compare bx_masterdesk with 8 mastering programs and rate how well it serves its purpose on three criteria. The basis is official manufacturer information.

Summary

Among the 8 mastering programs, bx_masterdesk is rank C. The ranks run S, A, B and C, and C is the lowest. Averaging the scores for each criterion (out of 5, with the one criterion that matters most for the purpose counted double) gives 1.5.

Things to keep in mind

• AI finishing (1 points): its AI finishing is limited.
• Fine adjustment (2 points): there is little room to work in detail.
• Pre-release checks (1 points): it has few checking features before export.

Who it suits: people who want to finish with an analog character using presets and a few knobs rather than AI.

Main features of bx_masterdesk

Analog mastering gear in one

Mastering software is a tool that adjusts the volume and tonal balance of a finished song so that it can go out on streaming or CD. The manufacturer explains that bx_masterdesk puts a chain of models of top-class mastering gear into a single plug-in.

Three-step operation

It is built to work in three steps: “Volume” sets how strongly the processing is applied, and “Foundation” and others set the base of the sound. There are many presets, and you can switch between them to look for a sound close to what you want.

Mid/Side features

The manufacturer explains that Mid/Side features (a method that processes the center and the sides separately) have been newly added.

Where it is useful

• Switching presets to find the direction of the finish quickly
• Moving Volume to see the balance between loudness and dynamics
• Setting the base of an analog-style sound with Foundation

Each criterion is scored from 1 to 5 on how well the product serves one goal: finishing cover songs and your own songs for streaming. Scores follow the conditions in the table above, and the rank is based on an average in which "Fine adjustment" counts double. The basis is official manufacturer information. Sound quality and CPU load are not measured, so they are not scored; reviews from trade magazines are introduced in the articles for reference. Price is not part of the score. Features that cannot be confirmed from the manufacturer's or a retailer's description are scored as if absent. At the moment we compare only the three editions of iZotope Ozone 12 and one product from IK Multimedia. The "OBS (streaming)" column in the table shows whether the official page lists the VST2 format that the streaming software OBS Studio can use (○). OBS does not support the VST3 format. It is not part of the score.
