Target entity: MPEG-2 AAC Context triple: [MPEG-1 Layer II audio, successorFormat, MPEG-2 AAC]
-
A.
HE-AAC v2
HE-AAC v2 is an advanced audio codec profile that combines AAC with spectral band replication and parametric stereo to deliver high-quality sound at very low bitrates, commonly used in streaming and broadcasting.
-
B.
ER-AAC
ER-AAC is an error-resilient variant of the Advanced Audio Coding (AAC) audio compression format designed to provide robust audio transmission over unreliable or lossy channels.
-
C.
MPEG-1 Layer II audio
MPEG-1 Layer II audio is a lossy audio compression format widely used in digital broadcasting and early digital media for efficient, good-quality stereo sound.
-
D.
MPEG-H
MPEG-H is a family of ISO/IEC standards developed by MPEG for advanced audio and multimedia coding, including immersive and 3D audio applications.
-
E.
MPEG-1 Audio Layer III
MPEG-1 Audio Layer III, commonly known as MP3, is a widely used digital audio encoding format that compresses sound data to significantly reduce file size while maintaining acceptable sound quality.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
