...you need to calculate the square root of the sum of the square of its real and imaginary components. That is, if your coefficient is a + b*j, then its magnitude is sqrt(a^2 + b^2). Once you have calculated the magnitude of each FFT coefficient, you need to figure out which audio frequency each FFT ...

... we can do about that now though. But the important thing is it does work, and it works in all browsers (even IE6/7), so use it if you like it. The additional markup for clearing may not be necessary if you use the :after selector to clear the floats, but this isn't an option if you want to suppor...

... One is an array of arrays, and one is a 2d array. The former can be jagged, the latter is uniform. That is, a double[][] can validly be: double[][] x = new double[5][]; x[0] = new double[10]; x[1] = new double[5]; x[2] = new double[3]; x[3] = new d...

...e its inner loop can be efficiently implemented on most architectures, and in most real-world data, it is possible to make design choices which minimize the probability of requiring quadratic time. Note that the very low memory requirement is a big plus as well. ...

... Your code is idiomatic and in my opinion it is the best practice available. Some would disagree for sure, but I would argue that this is the style seen all over the standard libraries in Golang. In other words, Go authors write error handling in th...

...to the source. If the changes affect functionality of the overall module, and may be useful to others, you may want to contribute to the original source on github and look for the change to be implemented. If this is proprietary functionality that is needed, and would not help the development of t...

... The function declaration is magic and causes its identifier to be bound before anything in its code-block* is executed. This differs from an assignment with a function expression, which is evaluated in normal top-down order. If you changed the example to sa...
