Beehive States for MTEB

This artifact contains the two official full-mode Beehive States folds from HEAR release 2021.3. Each fold contains the same 576 ten-minute, mono, 48 kHz PCM16 NU-Hive recordings, but preserves HEAR's released preprocessing output and cross-hive split independently. Fold 0 trains and validates on Hive 1 and tests on Hive 3; fold 1 reverses the hives. Labels are NOQUEEN and QUEEN.

The 576 IDs and labels agree across folds, but none of the corresponding WAV payloads are byte-identical. Consumers must therefore use the audio from the selected configuration instead of treating the two folds as split metadata over one shared audio table.

The source recordings are from NU-Hive Zenodo record 2667806. The exact preprocessed archives are from HEAR Zenodo record 6332517:
