MeldaProduction MAnalyzer vs MiniMeters

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.

MiniMeters is an audio metering application and plug-in suite for Windows, macOS, and Linux. The standalone app can monitor stereo input or supported system output, or receive audio from its Audio Server plug-in. Its modules display VU, waveform, spectrogram, spectrum, stereometer, loudness, and oscilloscope measurements. Users can arrange meters in a horizontal bar, separate them into windows, or use Quad Layout. MiniMeters can record audio directly and clip the previous 10 or 60 seconds of received audio. Individual plug-ins come in VST3, CLAP, and Audio Unit formats, and require a compatible host. The maker describes it as a display tool for measurements, not an audio processor. The no-time-limit demo is limited to Waveform and Loudness modules and places demo text on screen. The paid product costs 20.00 USD once, with a minimum price of $20 USD, and includes the standalone app, Audio Server plug-in, and meter plug-ins. Minimum requirements include Windows 10, macOS 10.15, or Linux kernel 5.4.0-174; macOS 14.2 is required for audio output capture.
