I wan\'t 开发者_如何学Pythonto try some beat detection algorithms from here in Java. My problem: How do I get the current audio mix from the soundcard as datasource for the algorithms?Check out the Ja
Rebuilding original signal from frequencies, amplitude, and phase obtained after doing an fft. Greetings
I\'m using: http://introcs.cs.princeton.edu/java/97data/FFT.java.html to implement my own low-pass filter.
I\'d like to be able to recognise a specific sound in an iOS application. I guess it would basically work like speech recognition in that it\'s fairly fuzzy, but it would only have to be for 1 specifi
can anyone tell me what is correct result after Fast Furier Transform, if input array is {0,1,2,3,4,5,6,7}.
I have been spending quite a bit of time studying FFT\'s.I am in particular interesting in using KISSFFT because it is a very portable C implementation.
I\'m currently working on a program that analyses a wav file of a solo musician playing an instrument and detects the notes within it.To do this it performs an FFT and then looks at the data produced.
I am currently studying image processing. In Scipy, I know there is one median filter in Scipy.signal. Can any开发者_JS百科one tell me if there is one filter similar to high pass filter?
I have written some code to try to swap quadrants of a 2D matrix for FFT purposes,that is stored in a flat array.
I\'m an engineering student and I have to solve an academic problem regarding signal processing. Basically, given an DTMF signal in wav format, I have to identify the number sequence it has encoded.
