Mastering The Mix EXPOSE 2 analysis app: features and spec-based rating

Mastering The Mix’s EXPOSE 2 is an app (a standalone app, not a DAW plug-in) that analyzes loudness (how loud a person perceives the sound), peak, stereo width and phase, and dynamic range just by dropping a song file onto the screen. You can choose where you will release it, such as Spotify or YouTube, compare the balance of the sound with a reference track and see advice on how to fix problems.

A loudness meter measures how loud a song sounds. You use it to check that a track fits the loudness guidelines of streaming services such as YouTube and Spotify.

In this article we compare EXPOSE 2 with 10 loudness meters and rate how well it serves its purpose on three criteria. The basis is official manufacturer information.

Summary

Among the 10 loudness meters, EXPOSE 2 is rank S. The ranks run S, A, B and C, and S is the top. Averaging the scores for each criterion (out of 5, with the one criterion that matters most for the purpose counted double) gives 4.5.

Strengths

• Streaming checks (4 points): you can quickly check that a track fits the targets of each streaming service.
• Measurable values (5 points): it can measure a wide range of values about volume.
• Finding problems (5 points): it finds and tells you about problems other than volume.

Who it suits: people who want to check exported songs all at once before releasing them to streaming.

Main features of EXPOSE 2

A standalone app that checks the files you give it

EXPOSE 2 is not a plug-in for your DAW but a standalone app that checks finished audio files. Drag a file in and it examines loudness, true peak, dynamics, the balance of the sound, stereo width and phase, and points out what to watch for. It suits the last check before you release.

Streaming targets and the balance of the sound

On screen you can choose where people will listen to the music, such as Spotify, YouTube or CD, and check against it. Load a reference song or choose a genre preset, and it shows how different the balance of your sound is from it.

Advice on how to fix problems

Problems it finds come with advice on how to fix them. It can find true-peak clipping, over-crushed dynamics, harsh or muddy sounds, phase and mono problems, and level outside the target.

Where it is useful

• Doing a last check of a finished song before releasing it to streaming
• Comparing with a reference song to check differences in the balance of the sound
• Checking several songs together to even out the volume of an album

Rating by criterion

Streaming checks: 4 / 5

We check whether you can confirm that a track fits the targets of each streaming service.

You can choose where you will release, such as Spotify, YouTube or CD, and check against it.

Measurable values: 5 / 5

We check how many values it can measure, such as loudness, loudness range and the risk of clipping (true peak).

It analyzes loudness (overall and short-term), true peak, dynamic range and loudness range (the spread of volume within a song).

Finding problems: 5 / 5

We check whether it finds and tells you about problems other than volume (such as the balance of the sound).

It analyzes stereo width and phase, dynamic range and the balance of the sound against a reference song, and shows advice on how to fix problems.

How we score (Loudness meters)

Criterion	Basis	5 pt	4 pt	3 pt	2 pt	1 pt
Streaming checks	Whether you can check against the targets of streaming services	Streaming-service targets, plus automatic loudness adjustment and a preview of how it sounds after audio compression	Targets for each streaming service (presets)	Presets for standards such as broadcast	It only measures numbers	—
Measurable values	How many of loudness, loudness range, true peak and PLR or dynamic range it can measure	All four	Three	Two	One	—
Finding problems	Analysis and advice beyond volume	Three or more kinds of analysis, plus advice on how to fix problems	Three or more kinds (stereo width, frequency distribution, dynamics and so on)	One or two kinds	No analysis beyond volume	—

Each criterion is scored from 1 to 5 on how well the product serves one goal: checking that a song can be released at a volume suited to streaming services. Scores follow the conditions in the table above, and the rank is based on an average in which "Streaming checks" counts double. The basis is official manufacturer information, and features that could not be confirmed on the official page are treated as absent. Measurement accuracy has not been tested, so it is not part of the score. 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. 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.
