Decibel vs MeldaProduction MAnalyzer

Decibel provides customizable real-time audio metering for sound engineers and video makers, and can also analyze tracks offline. Its modules measure loudness (LUFS), dynamics (TrueDyn), true peak, RMS, frequency content, and stereo phase. Users can drag a track into the app for offline analysis and export measurement statistics. Available analysis views include LUFS, histogram, spectrum, spectrogram, VU, digital meter, phase scope, stereo cloud, and super meter. Decibel comes as 64-bit AU, VST3, and AAX plugins, plus a standalone version. The product page lists compatibility with Pro Tools, Cubase, Logic Pro X, Ableton, Studio One, and Luna, as well as Premiere Pro; DaVinci Resolve and Final Cut Pro are described as coming soon. It can connect unlimited iOS and Android displays over Wi-Fi or USB for real-time metering. Decibel is listed for Windows, macOS, iOS, and Android. The maker says it complies with ATSC A/85, EBU R128, Netflix, and DVD/Blu-ray broadcast standards. Licenses are perpetual and include free updates, with no subscriptions.

MeldaProduction MAnalyzer is a free audio effect for spectral analysis and sonograms, available on macOS and Windows. It can analyze audio in real time or from offline files, with spectrum, sonogram, peak-meter and loudness-meter views. The loudness meter complies with EBU R128 and ITU-R BS 1770-3. Spectrum tools include smoothing, normalization, super-resolution, prefiltering and deharmonization. MAnalyzer is included in the MFreeFXBundle, which lists it among 38 effects for analysis and mastering. The bundle's professional upgrade adds sonogram access in analyzers and equalizers, along with other features. MAnalyzer runs as a plugin in compatible 64-bit hosts: listed Windows formats are VST, VST3 and AAX, while macOS also lists AU. Linux is not directly supported, though the maker says its plugins may run through Wine. The product page labels MAnalyzer a free effect; the listed bundle plan costs nothing.
