Target class: audio compression format Context triple: [HE-AAC v2, instanceOf, audio compression format]
-
A.
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.
-
B.
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.
-
C.
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.
-
D.
video compression standard
A video compression standard is a defined set of algorithms and rules that specify how digital video is encoded, transmitted, stored, and decoded to reduce file size while maintaining acceptable visual quality.
-
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.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
