分析30个流派音频数据，发现母带阶段音量问题最严重但压缩效果更好
Exploring trends in audio mixes and masters: Insights from a dataset analysis
- 基于MixCheck平台30个流派的混音与母带数据，量化评估音量、相位、压缩等指标
- 母带阶段虽音量问题更突出，但动态范围控制和压缩处理优于混音阶段
- 母带音频相位与立体声场问题更少，说明后期优化有效提升音频质量
我们对MixCheck Studio平台提供的音频指标与美学考量数据集进行了分析。该平台面向业余音乐制作人，用于发布前评估其录音。分析涵盖30个用户指定流派的集成响度、单声道兼容性、削波与相位问题、压缩程度及频谱轮廓。研究对象包括混音（tracks的初始组合与平衡）与母带（为发行优化的最终版本）。结果显示，母带音频中响度相关问题及动态范围问题最为普遍；然而，母带在压缩处理上优于混音；同时，母带音频的立体声场与相位问题比例更低。
原文摘要 · Abstract (English)
We present an analysis of a dataset of audio metrics and aesthetic considerations about mixes and masters provided by the web platform MixCheck studio. The platform is designed for educational purposes, primarily targeting amateur music producers, and aimed at analysing their recordings prior to them being released. The analysis focuses on the following data points: integrated loudness, mono compatibility, presence of clipping and phase issues, compression and tonal profile across 30 user-specified genres. Both mixed (mixes) and mastered audio (masters) are included in the analysis, where mixes refer to the initial combination and balance of individual tracks, and masters refer to the final refined version optimized for distribution. Results show that loudness-related issues along with dynamics issues are the most prevalent, particularly in mastered audio. However mastered audio presents better results in compression than just mixed audio. Additionally, results show that mastered audio has a lower percentage of stereo field and phase issues.
