MeldaProduction’s MLoudnessAnalyzer is a loudness meter that follows EBU R128 and ITU-R BS.1770-3. It can display a peak meter, momentary, short-term and integrated loudness (how loud a person perceives the sound) and loudness range (the spread of volume within a song).
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 MLoudnessAnalyzer 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, MLoudnessAnalyzer 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 2.3.
Things to keep in mind
- Streaming checks (2 points): it has few functions for checking against each streaming service.
- Finding problems (2 points): it is mainly for measuring volume.
Who it suits: people who only need to check basic loudness numbers, for free.

Rating by criterion
Streaming checks: 2 / 5
We check whether you can confirm that a track fits the targets of each streaming service.
It measures numbers following EBU R128 and ITU-R BS.1770-3.
If “streaming checks” matters most to you, MasterCheck (5 points) is a better fit.
Measurable values: 3 / 5
We check how many values it can measure, such as loudness, loudness range and the risk of clipping (true peak).
It can measure momentary, short-term and integrated loudness, and loudness range. A peak meter is also included.
Finding problems: 2 / 5
We check whether it finds and tells you about problems other than volume (such as the balance of the sound).

If “finding problems” matters most to you, EXPOSE 2 (5 points) is a better fit.
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.
