The Fraunhofer MPEG-H decoder (mpeghdec) is a C/C++ implementation of the MPEG-H Audio standard as defined in ISO/IEC 23008-3:2022. MPEG-H Audio is the Next Generation Audio (NGA) codec for personalized and immersive sound. Please visit www.mpegh.com to learn more about MPEG-H Audio.
The mpeghdec software implementation provides 2 modules for the integration of MPEG-H Audio in consumer devices / consumer software:
- MPEG-H decoder
- MPEG-H UI manager
The MPEG-H decoder module, exposed by the include/mpeghdecoder.h API, is used to decode the MPEG-H Audio bitstream. The decoding can be performed to one of the supported MPEG-H Decoder Target Layouts and depends on a set of MPEG-H decoder parameters.
| IMPORTANT |
|---|
| Please make sure to adapt the default target loudness and DRC effect type parameters according to the applicable device class. |
The MPEG-H UI manager module, exposed by the include/mpeghUIManager.h API, is used to implement MPEG-H interactivity handling. To learn about MPEG-H interactivity, please visit the following resources:
| MPEG-H Audio Profile | MPEG-H Audio Level |
|---|---|
| Baseline | Level 4 |
Additional information about the supported transport formats can be found here.
