AI Summary

Improves core audio processing with language alias normalization, VAD event handling, and CUDA cache management.

Key Highlights

  • NLLW language aliases normalize Whisper Chinese codes (zh -> zh-CN)
  • VAD event handling preserves short silence boundaries
  • CUDA cache cleanup optimized for lightweight per-step release

New Features

  • Normalize language codes at NLLW boundary
  • Preserve timestamp drift in VAC/VAD chunk processing
  • Keep CUDA cache release on coarse segment boundaries

Full Release Notes

## Core
- **NLLW language aliases** : Normalize Whisper Chinese language codes at the NLLW boundary (`zh` -> `zh-CN`) for transcription and translation configs
- **VAD event handling** : Preserve short silence boundaries and avoid cumulative timestamp drift in VAC/VAD chunk processing
- **CUDA cache cleanup** : Keep per-step decoder cleanup lightweight; CUDA cache release stays on coarse segment boundaries
