The dual‑track nature of 2‑AVI ensures lossless audio preservation (24‑bit PCM) while maintaining high‑definition video. Compared with the MP4 control files, 2‑AVI retained full dynamic range, a crucial factor for future scholarly analysis of vocal timbre (Kumar & Liu, 2020). However, 2‑AVI files are larger (≈ 1.8 GB for a 10‑minute set) and require dedicated playback software, a limitation for congregational streaming that can be mitigated by generating derivative MP4s for public use while keeping 2‑AVI masters for archive.
