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.
