Implementierungsnotizen

• The runtime resamples mono Float32 PCM to 16 kHz and handles long recordings in overlapping chunks.
• INT5 is the practical default: on the validated English FLEURS run it used a 1.62 GiB bundle, 2,582 MiB physical footprint, and 0.0150 mean RTF.
• MLX affine quantization supports 2, 3, 4, 5, 6, and 8 bits, not INT7; choose INT8 when prioritizing quality.
• This is a non-streaming engine. The CLI rejects --stream instead of silently changing behavior.
• The published benchmark covers English read speech and does not claim parity with conversational, telephone, noisy, or speaker-heavy benchmarks.
