I have two 2-D arrays with the same first axis dimensions. In python, I would like to convolve the two matrices along the second axis only. I would like to get C below without computing the convolutio
In their book \"Digital Signal Processing\" Proakis & Manolakis describe a Method for computing the FFT of a real Signal of length 2N using a FFT of length N. This is basically done by splitting t
I have an array of int samples ranging from 32766 to -32767. In part of trying to create an envelope detector I\'ve written a low pass filter, but it doesn\'t seem to开发者_StackOverflow社区 be doing
I have an array of 240 data points sampled at 600hz, representing 400ms.I need to resample this data to 512 data points sampled at 1024hz, representing 500ms.I assume since I\'m starting with 400ms of
Hello kind people of the audio computing world, I have an array of samples that respresent a recording. Let us say that it is 5 seconds at 44100Hz. How would I play this back at an increased pitch? A
I am trying to implement the overlap and add method in oder to apply a filter in a real time context. However, it seems that there is s开发者_如何学编程omething I am doing wrong, as the resulting outp
I have two time series of 3D accelerometer data that have different time bases (clocks started at different times, with some very 开发者_运维百科slight creep during the sampling time), as well as cont
I have two arrays of samples of two different audio clips. If I just programmatically add them together will this be the equivalent of layering one track over another in an audio editing suite? Like i
Are there any good (if possible scientific) resources available (web or books) about overlap processing. I am not that interested in the effects of using overlap processing and windows when analyzing
开发者_开发百科How can we get the amplitude,time values of an audio signal in java. I need to detect the peaks in the signal using these values.Here\'s one web page describing the most common .wav(RIF
