AAC Audio ES Viewer is an advanced software application that lets you visually analyze Advanced Audio Coding files (AAC format), namely their audio elementary stream (ISO/IEC 13818-7). It supports hex viewing mode, among other practical features.

Installing this program is a speedy job that shouldn't give you any trouble. Once it's over, you are greeted by a common-looking window with a minimalistic structure, where you can get started by opening an AAC file. The tool also supports MPEG, MPG, TS, M2TS, MP4 and MXF file types.

You can examine the offset, length, ID, number of layers, sample rate, profile number, and channel configuration for each frame, as well as click any entry to get detailed information about the headers, in addition to the hexadecimal code.

Edit frames, validate media, and generate reports

It's possible to copy data selections to the Clipboard, edit any frame in hexadecimal form, create plots for stream frames, as well as validate media, configure validation settings (ID, name, report type, enabled or disabled, description), as well as generate and save reports to file.
