this is a continuation of this question here. This is the code I used in order to get the samples: spf = wave.open(speech,\'r\')
I used fft function in numpy which resulted in a complex array. How to开发者_StackOverflow社区 get the exact frequency values?np.fft.fftfreq tells you the frequencies associated with the coefficients:
im trying to implement a gaussian blur with the use of FFT and could find her开发者_开发技巧e the following recipe.
I want to write a program in Java that uses fast Fourier transformation. The program reads data every 5 milliseconds seconds from sensors and is supposed to do something with the data every 200 millis
Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.
Yesterday I finalised the code for detecting the audio energy of a track displayed over time, which I will eventually use as part of my audio thumbnailing project.
Does anybody know what the frequency range of auriotouch is in FFT mode?Also, where is it defined in the code if possible.I\'ve been digging through it, but am not开发者_如何学编程 very familiar with
Has anybody used the Apple FFT for an iPhone app yet or know where I might find a sample application as to how to use it?I know that Apple has some sample code posted, but I\'m not really sure how to
I\'m implementing a face tracker on Android, and as a literature study, would like to identify the underlying technique of Android\'s FaceDetector.
I\'ve been reading a lot about Fast Fourier Transform and am trying to understand the low-level aspect of it. Unfortunately, Google and Wikipedia are not helping much at all.. and I have like 5 differ
