For the temporal path, we study task<br>accuracy as a function of sequence length with zero-padding<br>and interpolation to 128 samples. Across six SNR bins from<br>\u221210 dB to 20 dB, we demonstrate critical thresholds: spectral<br>performance degrades sharply below 256 bins, while temporal<br>accuracy benefits monotonically from longer sequences up to<br>128 samples.
