And mode is taken to multiple FFT results, the accuracy of FFT result can be improved, and then improve the accuracy of parsing result.
The default pointer is continued to move along preset quantity sampled point by step c5, to obtain the frequency of next character
Rate, and so on, until stopping moving forward when the frequency of the character obtained is default end mark frequency, to obtain sound wave frequency
Rate sequence.
The default pointer is continued to move along into preset quantity sampled point, to obtain the frequency of next character, specifically,
(such as away from default pointer current location at the sampled point of the position preset interval behind the position after default pointer is mobile and away from movement
+ 10, -10 ,+20, -20 places) FFT window is respectively created, and FFT transform is carried out, and corresponding multiple FFT results are obtained, it is then right
Multiple FFT results take mode to get the frequency of character is corresponded to at the position after movement.The rest may be inferred, until the character obtained
Frequency stop moving forward when being default end mark frequency, to obtain frequency of sound wave sequence.
