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.
I am implementing MFCC algorithm in Java. There is a sample code here: http://www.ee.columbia.edu/~dpwe/muscontent/practical/mfcc.m at Matlab. However I have some problems with mel filter banking pr
I\'m looking at some image processing algorithms for white balance manipulations. Seems like a previous Stackoverflow question answers the question of automatic white balance algorithms rather well.
Can someone please tell me what is wrong here. delay has a buffer (del) with a pointer *p, but is outputting zero (0) every sample.
I am currently thinking about what I could do to measure the time it takes from the point where the computer gets audio input (t开发者_开发问答hrough a normal audio input on a soundcard) to the point
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical andcannot be reasonably answered in its current form. For help clari
I\'mdeveloping a digital audio synthesizer on a dsPIC. To begin with Im writing and testing the algorithms in matlab.
I am a bit stuck here as I cant seem to find some algorithms in trying to distinguish whether a sound produced is a chord or a single note. I am working on Guitar instrument.
I have a simple EEG signal in MATLAB such as that shown in the figure below. And what I wanted was to extract the components of the EEG according to the following table.
I have created a simple Chebyshev low pass filter based on coefficients generated by this site: http://www-users.cs.york.ac.uk/~fisher/mkfilter/, which I am using to filter out frequencies above 4kHz
