AAC Audio ES Viewer Pro – The Audio Elementary Stream Revealed

AAC Audio ES Viewer solution provides a structural representation of Advanced Audio Coding (AAC) audio elementary stream compliant with the ISO/IEC 13818-7 specification. The AAC audio frames sequence can be investigated along with the most common parameters of each audio frame in the application’s list view. Detailed AAC audio frame headers information is available in the application’s tree view. Hexadecimal representation of the AAC audio elementary stream file is available in the Hex View module.

AAC Audio ES Viewer Pro additionally provides ADTS AAC audio stream verification and validation according to the ISO/IEC 13818-7 audio format standard.

All stream errors, such as incorrect audio stream structure or invalid header values, pointed as mandatory in the corresponding specification are output as Error Report. All audio stream irregularities, which are not pointed as mandatory in the corresponding specification, but have unusual content are output as Warning Reports. Additionally there is a set of Informational Reports, which deliver more detailed information about the file being examined, such as the stream format, media duration, etc.
