In order to realize a noise octave analysis by software, a digit weight method based on FFT is proposed.
为了利用软件实现噪声倍频程分析，提出了一种基于FFT的数字计权方法。
A lot of complex functions, such as 1/3 octave analysis, sound power, tonality narrow band analysis, vibration spectrum, have been solved.
解决噪声1/3倍频程、声功率、音调窄带谱，振动频谱等复杂功能的在线分析与处理。
The usual stored information may consist of the 'a' Weighted Leq, LN values, SPL values and perhaps 1:3 Octave Band information for tonal analysis.
通常存储的信息可能包括的'a '加权的Leq,LN的值，声压值，也许1：3倍频为音调分析信息。
That being said, I don't recommend the DWT for music and sound analysis because the analysis bands are fixed at one-octave, which is simply too wide to do anything meaningful with.
也就是说，我不推荐DWT的音乐和声音的分析，因为分析带被固定在一个倍频程，这简直是太宽做任何有意义的。
