Target class: perceptual audio coding tool Context triple: [Spectral Band Replication, instanceOf, perceptual audio coding tool]
-
A.
audio coding tool
chosen
An audio coding tool is a software or hardware component that compresses, encodes, and decodes digital audio signals to efficiently store, transmit, and reproduce sound with minimal loss of quality.
-
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.
psychoacoustic model
A psychoacoustic model is a conceptual framework that predicts how humans perceive sound by simulating auditory system characteristics such as masking, loudness, and frequency resolution.
-
D.
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.
-
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.
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.
