Target class: digital audio compression format Context triple: [Dolby AC-4, instanceOf, digital audio compression format]
-
A.
digital audio codec
A digital audio codec is a system or algorithm that encodes and compresses audio signals into a digital format for storage or transmission and decodes them back into audio for playback.
-
B.
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.
-
C.
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.
-
D.
lossy compression standard
chosen
A lossy compression standard is a formally defined method for reducing data size by irreversibly discarding less perceptible information while maintaining acceptable quality for its intended use.
-
E.
MPEG-4 audio profile
An MPEG-4 audio profile is a standardized set of audio coding tools and constraints within the MPEG-4 framework that defines the capabilities, complexity, and interoperability of encoded audio streams.
- F. None of above.
