因为录音质量的标准是由音色、平衡、信噪比、频响及动态范围等一系列主客观评价因素的集合所决定,所以我们今天讨论的响度仅限于唱片在商业运作中的考虑,而不会也永远不会成为评价唱片录音质量的标准。并且响度作为一个心理声学研究成果,运用到今天的制作或出版业当中,大概已经违背了当初无论是罗宾逊还是弗莱舍的初衷。 响度首先取决于声波振幅,所以在数字录音领域首先考虑的是信号存储系统的峰值储备。我们知道目前Peak表的最大解析度为OdBFs,所以区别于模拟录音中VU表头的使用,在这里,我们必须保
Because the standard of recording quality is determined by a set of subjective and objective factors such as tone, balance, signal-to-noise ratio, frequency response, and dynamic range, the loudness we discuss today is limited to the consideration of the recording in commercial operations, Will never be a standard for evaluating the quality of recordings. And loudness as a psychoacoustic research, applied to today’s production or publishing industry, has probably violated the original intention of both Robinson or Fleischer. The loudness first depends on the sound wave amplitude, so the first consideration in the field of digital recording is the peak reserve of the signal storage system. We know that the maximum resolution of the Peak table is OdBFs, so different from the use of VU header in analog recording, here we must protect
