MPEG Audio ES Viewer Pro – See Inside the MPEG Audio
MPEG Audio ES Viewer Pro solution provides a structural representation of MPEG audio elementary stream compliant with the ISO/IEC 11172-3 and ISO/IEC 13818-3 specifications. The application supports the most popular broadcast MPEG-1 Audio Layer I and MPEG-1 Audio Layer II formats as well as the most popular end-user MPEG-1 Audio Layer III format.
The MPEG audio frames sequence can be investigated along with the most common parameters of each audio frame in the application’s list view. Detailed MPEG audio frame header information is available in the application’s tree view. Hexadecimal representation of the MPEG audio elementary stream file is available in the Hex View module. The solution is useful for detailed MPEG Audio Layer I/II/III elementary streams investigation and error detection.
MPEG Audio ES Viewer Pro also provides MPEG audio stream verification and validation according to the ISO/IEC 11172-3 and ISO/IEC 13818-3 audio format standards.
The currently loaded file in the MPEG Audio ES Viewer Pro can be validated by selecting “Validation” from the “Tools” menu.
Apart from the manual MPEG audio media validation provided in the MPEG Audio ES Viewer Pro solution, Jongbel Media Solutions also provides automated MPEG audio stream media validation in its Media Validator solution.

MPEG Audio ES Viewer Pro’s General Info
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.
Each MPEG audio stream check can be disabled or enabled or set to another report type, such as Info, Warning or Error. The solution can be applied in wide variety of workflows and with many container format deviations due to its flexibility and customization ability.
The validation report output can be exported into XML report file, containing the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.
The validation takes only a few seconds for an average long and complex media file to be processed.
