用低延迟音频框架让全球南方音乐教育更公平
Bridging Cultural and Digital Divides: A Low-Latency JackTrip Framework for Equitable Music Education in the Global South
- 基于开源UDP协议，适配低带宽高延迟环境
- 实测延迟低于30毫秒，保留微音程等文化细节
- 适合关注数字公平与非西方音乐传承的团队
数字技术虽已普及，但全球南方仍面临基础设施与文化鸿沟。本文提出一种低延迟的JackTrip框架，基于斯坦福CCRMA开发的开源UDP音频流协议，针对农村和欠发达地区常见的间歇性连接、带宽有限和高延迟问题进行优化。在模拟低资源条件下，该框架将延迟控制在30毫秒以下，显著优于传统平台如Zoom。谱分析表明，其能精准还原非西方音乐传统的微音程、复杂节奏与和声纹理，支持实时合奏与教学。研究证实，去中心化、边缘计算方案在推动全球南方教育公平与文化传承方面具有变革潜力。
原文摘要 · Abstract (English)
The rapid expansion of digital technologies has transformed educational landscapes worldwide, yet significant infrastructural and cultural challenges persist in the Global South. This paper introduces a low-latency JackTrip framework designed to bridge both the cultural and digital divides in music education. By leveraging an open-source, UDP-based audio streaming protocol originally developed at Stanford's CCRMA, the framework is tailored to address technical constraints such as intermittent connectivity, limited bandwidth, and high latency that characterize many rural and underserved regions. The study systematically compares the performance of JackTrip with conventional platforms like Zoom, demonstrating that JackTrip achieves sub-30~ms latency under simulated low-resource conditions while preserving the intricate audio details essential for non-Western musical traditions. Spectral analysis confirms that JackTrip's superior handling of microtonal scales, complex rhythms, and harmonic textures provides a culturally authentic medium for real-time ensemble performance and music education. These findings underscore the transformative potential of decentralized, edge-computing solutions in empowering educators and musicians across the Global South, promoting both technological equity and cultural preservation.
