MiniMeters vs Room EQ Wizard

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.

Room EQ Wizard (REW) is measurement and analysis software for working on listening-room, studio, and home-theater acoustics, speaker and subwoofer placement, audio-chain performance, and EQ. It measures frequency response and distortion with logarithmic swept sine signals and supports USB or analog measurement microphones and SPL meters. Its views include impulse and step responses, energy-time curves, spectral decay, waterfalls, spectrograms, reverberation times, distortion, phase, group delay, and real-time analysis. REW's signal generator produces tones, sweeps, bursts, and noise, among other signal types, with WAV export. Its EQ tools identify response peaks, assign filters, optimize filter parameters, and display predicted EQ waterfalls live. The Room Simulator supports up to eight subwoofers. The free plan includes single-channel capture, measurement, real-time analysis, and EQ tools. REW runs on Linux, macOS, and Windows.
