Media Checker
Read what is really inside a media file: container, codec, sample rate, bitrate, dimensions, encoding and measured levels.
Eight inspection tools that parse container headers directly — RIFF chunks, MPEG frame headers, FLAC streaminfo, MP4 sample tables and Matroska EBML — and decode the media to report measured duration and levels rather than claimed values.
