LANDR Mastering Plugin AI mastering software: features and spec-based rating

LANDR’s mastering software LANDR Mastering Plugin is a plug-in for your DAW (the software you make music in) in which AI analyzes a song and builds the mastering settings. You can choose a finishing style, and it has controls such as EQ, de-esser, stereo width and dynamics, and a loudness meter.

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

In this article we compare LANDR Mastering Plugin 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, LANDR Mastering Plugin 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 2.5.

Things to keep in mind

• Pre-release checks (1 points): it has few checking features before export.

Who it suits: people who want to finish quickly by leaving it to AI, even without knowledge of mastering.

Main features of LANDR Mastering Plugin

AI analyzes the song

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. LANDR Mastering Plugin analyzes a song with what the manufacturer calls an “AI mastering engine”, and lets you work while listening to the finished sound inside your DAW.

Styles and adjustment controls

The official page lists controls such as Mastering Styles, EQ, Presence, De-Esser, Stereo Width, Dynamics and Loudness. After choosing the direction of the finish, you can adjust several of the controls yourself.

Meters and gain comparison

It lists a loudness meter, an output meter, an input trim and gain matching (a feature that evens out the volume so you can compare). The manufacturer explains that because you can work while listening inside the DAW, it saves the trouble of redoing exports.

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.
