-
A.
Modified Discrete Cosine Transform
chosen
Modified Discrete Cosine Transform is a lapped transform widely used in audio coding and compression (e.g., MP3, AAC) to efficiently represent overlapping time-domain signals in the frequency domain with reduced artifacts.
-
B.
Cooley–Tukey Fast Fourier Transform algorithm
The Cooley–Tukey Fast Fourier Transform algorithm is a widely used, efficient method for computing the discrete Fourier transform that revolutionized digital signal processing and numerical analysis.
-
C.
Daubechies wavelets
Daubechies wavelets are a family of compactly supported orthogonal wavelets widely used in signal processing and image compression for their efficient time-frequency localization.
-
D.
Haar wavelet
The Haar wavelet is the simplest and oldest wavelet function, used as a basic building block in wavelet analysis for representing signals with abrupt changes.
-
E.
Subband Codec
Subband Codec (SBC) is an audio compression format commonly used over Bluetooth for efficiently transmitting medium-quality stereo sound with relatively low computational complexity.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
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.
