通过中国唱片总公司举行的盒式音带音质评比(主要是与高质量盒座普通速度复录盒带的对比)的结果和分析,揭示了高速复制给盒带音质带来的变化。结果表明,当复制系统技术指标高于(至少应达到)ZB M71002—89标准的规定时,高复的音质可以相当接近于普通高质量复录音质。通过不同类型节目音质变化的详细分析,可知高复较易损失的是丰满度和力度,而保持最好的是空间感和清晰度。
The result of analyzing the quality of the cassette tapes (mainly compared with the ordinary cassette tapes of high quality cassette) held by China Record Corporation revealed the changes brought by high speed copying to the sound quality of the cassettes. The results show that when the copy system specifications above (at least to meet) ZB M71002-89 standards, high complex sound quality can be quite close to the ordinary high-quality sound reproduction. Through the detailed analysis of the changes in the sound quality of different types of programs, it can be seen that the high recovery is more likely to lose fullness and intensity, while maintaining the best sense of space and clarity.
