I'd like to write a simple program(preferably in C#) to which I sing a pitch using a mic and the program identifies to which musical note that pitch corresponds. Thank you very much for your prompt responses. I clarify: I'd like a (preferably .NET) library that would identify the notes I sing. I'd like that such a library: Identifi...

I am working a school project to implement a Huffman code on text. The first part of course requires a frequency analysis on the text. Is there a better way aside from a giant switch and an array of counters to do it? ie: int[] counters for(int i = 0; i <inString.length(); i++) { switch(inString[i]) case 'A': counters[0]++; ...

So for example, I have a recording of a friend reciting a poem with a few percussion instruments in the background. Could I write a C program that goes through the entir...
This gives me a frequency of words in a text: fullWords = re.findall(r'\w+', allText) d = defaultdict(int) for word in fullWords : d[word] += 1 finalFreq = sorted(d.iteritems(), key = operator.itemgetter(1), reverse=True) self.response.out.write(finalFreq) This also gives me useless words like "the" "an" "a" My qu...
I need to count frequencies in the 0.1Hz to 1.99GHz range. At my disposal is a 16bit counter with an additional overflow bit, a timer accurate to 1uS, frequency dividers and a microcontroller to glue all these together. The logic I have decided to use is so: Condition the input signal to give a 50% duty cycle 5Vpp square wave Feed th...

My aim is to have a set of frequencies like 2 frequencies that represent the bits (0 and 1). I want to send those frequencies to the audio out through sound card. At the other end I connect the cord to mike in of the sound card. I like to sense that signal (generated series of 2 fixed frequencies) from other computer and re-form the data...
I was asked to make a software that will encrypt and decrypt a "normal English" text based on letter frequencies. The question is where do I find some text samples where the official frequencies will match? So far, I have tried "War and Peace" by Lev Tolstoy, it didn't work well.. LE: I don't need just a list of words, I need a text s...
