hi i recorded several wave sounds with sampling rate 8000 Fs=8000; y=wavrecord(5*Fs,Fs); i want to apply normalization to Excluding anomalous values from this sound
No products are associated with this question.
Then please take the time to explain any details: There are different methods to normalize a wave sound, e.g. that the rand is -1<=y<1, or -1<=y<=1, or -32768<=y<=32767, etc. You can normalize the frequency power, the loudness, the mean amplitude, the standard deviation, ...
Therefore I suggest to explain exactly what you need. Then post, what you have tried already to get rid of the "doit4me" tag, which reduces the motivation to create an answer.
