Piano Hammer Voicing
Hello, i'm doing a study on Hammer Voicing and i have 250 Wave files (all of La220) to analyze. The idea is to compare the differences in the Magnitude of each Harmonic to Plot the effects of each voicing procedure. How can i do that? Would it be something like: 1 - FFT of all Wave Files 2 - Pitch Detection 3 ... 22 May 2010 18:12

Discrete math question
Math question: Given 2^n possible arrangements of N 0s and 1s, how many of those are unique under cyclic permutations? For example, with N=3, we have (111,000,100,110), so the answer is 4. I'm not sure such a formula has ever been discovered. It certainly is NOT a trivial one. ... 28 May 2010 13:44

Orthogonal distance regression of parabolic data
Hello Everyone, I'm trying to fit a set of x, y measurements to a parabola. For a conic section: Ax^2+Bxy+Cy^2+Dx+Ey+F=0, most of fitting algorithms has B=0, making the curve symmetrical about the y-axis and which in turn, simplifies the process. In my case, however, B <> 0 which means the parabola is rotated. I ... 22 May 2010 12:44

resolution
Hello Friends, I am studying 2 images. When i use the function imfinfo on both I get more or less the same info(pertaining to bit depth,ColorType,Format,ImageDataOffset and BitmapHeaderSize). But, there are 2 parameters that are different viz - HorzResolution and VertResolution. In the first image the values are 0,0... 22 May 2010 11:38
