MeldaProduction MAnalyzer

MeldaProduction MAnalyzer is a free plug-in for detailed spectrum, sonogram, peak and loudness analysis. It suits music producers, engineers and mastering users who want these measurements inside a compatible DAW, with offline file inspection as well as live monitoring. The broad toolset is compelling at no cost, but users who need the bundle’s expanded sonogram and workflow features will need the professional upgrade.

Overview

MAnalyzer is an advanced normalizing spectral analyzer and sonogram delivered as an audio effect. It can analyze a signal in real time or examine an offline file, so it covers both decisions made during playback and more deliberate post-session checking. Spectrum processing includes smoothing, normalization, super-resolution, prefiltering and deharmonization. Those controls make it more useful than a single fixed spectrum display when you need to isolate detail, tame visual fluctuations or study harmonic content.

Peak metering sits alongside loudness measurement compliant with EBU R128 and ITU-R BS 1770-3. That combination lets one plug-in address frequency balance, transient level and broadcast-oriented loudness checks. It remains an analysis effect rather than an editor or complete mastering environment, so its value is greatest when your host already provides the surrounding production tools.

The effect is part of MFreeFXBundle, a collection of 38 effects categorized for analysis and mastering. The bundle’s professional upgrade unlocks sonogram features in analyzers and equalizers, plus plugin resizing and styling, preset management, modulators and upsampling for most plugins. MAnalyzer’s free core is therefore practical for measurement, while the paid tier is aimed at users who want a broader, more configurable MeldaProduction setup.

Key features

• Flexible spectrum views: Smoothing and normalization can make broad trends easier to read, while super-resolution, prefiltering and deharmonization provide alternative ways to inspect difficult spectral material. These are useful for diagnosing resonances and tonal balance rather than merely watching a generic frequency curve.
• Sonogram and spectrum analysis: Spectrum and sonogram views show frequency behavior over time in different ways. The professional bundle upgrade is relevant if you require the additional sonogram access it unlocks across analyzers and equalizers.
• Peak and loudness meters: Peak readings help identify level excursions; EBU R128 and ITU-R BS 1770-3 compliance gives loudness work a defined standards context. This is a stronger fit for production and mastering checks than a spectrum-only utility.
• Real-time and offline operation: Use it while a track plays or analyze a file away from the transport. That flexibility suits both mixing sessions and later quality-control passes.
• Host integration: The plug-in is offered in VST format and is designed for use in a DAW. MeldaProduction cites compatibility with hosts including FL Studio, Reaper, Cubase, Live, Studio One and Pro Tools.

Pricing

MAnalyzer (included in MFreeFXBundle) — free. The free effect provides the core analyzer at no charge, making it a sensible choice for anyone who needs spectrum, sonogram, peak and loudness views without a software budget. It does not include the professional bundle additions: expanded sonogram access in analyzers and equalizers, plugin resizing and styling, preset management, modulators and upsampling for most plugins. Choose the upgrade when those workflow and customization features matter across the bundle, not merely because you need basic metering.

Platforms

Windows support requires Windows 10 or 11, 64-bit, plus a 64-bit VST, VST3 or AAX-compatible host. On macOS, it requires 10.14 Mojave or newer, a 64-bit VST, VST3, AU or AAX host, and an Intel, AMD or Apple Silicon CPU. Linux is not directly supported, although MeldaProduction says its plug-ins may run through Wine. The maker describes compatibility with almost every host, but the plug-in format and host requirements still determine whether it fits your setup.

Who it's for

MAnalyzer is well suited to producers, mixing engineers and mastering users who want detailed spectral diagnosis plus standards-based loudness readings in one DAW effect. Offline analysis also helps anyone checking finished files after a session. It is less suitable as a standalone audio-analysis workstation, for Linux users seeking native support, or for engineers who specifically need the professional bundle’s expanded sonogram and modulation features.

Pros and cons

• Pro: A wide range of spectrum controls supports more targeted diagnosis than a basic analyzer.
• Pro: Peak metering and EBU R128/ITU-R BS 1770-3 loudness compliance cover important level checks in the same effect.
• Pro: Real-time and offline analysis serve both active mixing and file-quality review.
• Pro: The core effect costs 0.00 USD and is available on current Windows and macOS systems.
• Con: The free bundle omits professional sonogram access and several workflow features, so advanced users may outgrow it.
• Con: Linux has no direct support; Wine is the only route mentioned for running the plug-ins.
• Con: It depends on a compatible 64-bit plug-in host rather than functioning as a general standalone editor.

Alternatives

For a broader directory of choices, see Audio Analysis Software.

• MediaInfo is a free option for users who need digital-media analysis across Android, iOS, Linux, macOS, self-hosted, web and Windows environments rather than a DAW effect.
• Open Audio Analyzer is free on Android, iOS, Linux, macOS and Windows, making it a better fit when cross-platform coverage matters.
• Open Sound Meter offers a free community desktop version and open-source desktop development; choose it when that model and its Linux support appeal more than a plug-in workflow.
• Blue Cat's FreqAnalyst is a free real-time spectrum-analyzer plug-in for macOS and Windows, suited to users who want a narrower spectrum-focused tool.
• Dusk Audio Spectrum Analyzer is another free macOS, Windows and Linux choice for straightforward spectrum analysis.
• Friture is free and open source on Linux, macOS and Windows, preferable when native Linux availability and an open-source application are priorities.
• MiniMeters has a free demo with waveform and loudness modules and a 20.00 USD one-time plan; choose it if those focused meters and a paid desktop application suit you better.
• Praat is free software for Linux, macOS and Windows, offering a different analysis-oriented application approach.

Verdict

Choose MAnalyzer if you want a capable, no-cost analyzer plug-in that combines fine-grained spectrum controls, sonogram viewing, peak metering and standards-based loudness checks in a supported DAW. Its main reason to look elsewhere is the professional bundle boundary: users who need expanded sonogram access and the additional customization, preset, modulation and upsampling features should consider the upgrade or a different tool.
