MediaInfo vs Raven Lite

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.

Raven Lite records, saves, and visualizes sounds as spectrograms and waveforms. It is intended for students, educators, and hobbyists, including people learning about sound, recognizing birdsong, or teaching music. Users can combine waveform, spectrogram, spectrogram slice, and selection spectrum views. It opens WAV, AIF, MP3, and FLAC files, supports any number of audio channels, and lets users choose all channels or a subset. Time-frequency selections can be measured in a selection table and annotated; tables can be saved as text, while views and sound windows can be exported as graphics or copied to the clipboard. Paged sound windows support navigation through recordings of any length, and auto-paging enables visual review faster than real time. Raven Lite runs on Linux, macOS, and Windows. The free demo runs for 10 minutes at a time until registered with a free serial number for uninterrupted use. Installation requires administrator privileges.
