MediaInfo vs Room EQ Wizard

MediaInfo displays technical and tag information for video and audio files. It reports details about the container, video and audio streams, text, and chapters, and reads formats including MPEG-4, Matroska, AVI, MXF, H.264/AVC, H.265/HEVC, MP3, AAC, FLAC, SRT, and ASS. Results can be viewed in text, sheet, tree, or HTML form and exported as text, CSV, or HTML. The software is available as a graphical interface, command-line tool, and library, with operating-system shell integration through drag and drop and context menus. MediaInfo is open-source under a BSD-style license; its listed software price is free. MediaInfoOnline offers a browser-based option and states that files remain on the user's machine rather than being uploaded to MediaArea servers, though it is described as a technology preview. Downloads are listed for Windows, macOS, iOS, Android, and Linux distributions, as well as a JavaScript module and source builds. MediaArea separately offers integration, maintenance, development, and support services at unlisted prices.

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.
