  • A. multichannel audio format
    A multichannel audio format is a digital or analog audio configuration that uses more than two discrete channels to reproduce sound from multiple directions, enhancing spatial realism and immersion.
  • B. MPEG-4 AVC
    MPEG-4 AVC (also known as H.264) is a video compression standard that efficiently encodes digital video for storage and transmission while maintaining high visual quality at relatively low bitrates.
  • C. lossless audio codec
    A lossless audio codec is a method of encoding digital audio that compresses data without any loss of quality, allowing the original audio to be perfectly reconstructed during playback or decoding.
  • D. wideband speech codec
    A wideband speech codec is a digital encoding and decoding system that compresses and reconstructs speech signals over an extended frequency range (typically 50 Hz–7 kHz or higher) to improve clarity and naturalness compared to narrowband codecs.
  • E. speech codec
    A speech codec is a system that encodes and compresses spoken audio into a digital format for efficient transmission or storage and then decodes it back into intelligible speech.
  • F. None of above. chosen
