Magnitude Values within Fast Fourier Transformation FFT are different by constant input signal?
Within my Beat-Detection, I'm using a Fast Fourier Transformation to detect the bass within an audio Signal. Im recording a solo basedrum, not moving the sound or volume. After plotting the values over time. I get non constant values. They differ…

Finding magnitude of vector in given direction
I am writing a tool in Unity3D which allows dragging points to resize shapes:
The drag points can only be moved along the surface normal (i.e. the example cube could not become deformed, only elongated).
Naturally the mouse can be dragged in any…

How can i detect amplitude from FFT on Time-Domain signal
I have a signal of wave song and I have a problem with amplitudes.
%graph 1 time domain
song2 = song(1:size(song));
fs = 44100;
dt = 1/fs;
t = 0:dt:(length(song2)*dt)-dt;
figure();
plot(t,abs(song2)); xlabel('Seconds'); ylabel('Amplitude');
Then I…

Same magnitude on different axes?
Is it possible to take the magnitude of an object on one axis and put it inside of a variable and give it to a separate object on a different axis? Does magnitude not work that way?

How to fix y scale to include different magnitude orders to a barplot
I have several troubles plotting my data frame with ggplot2.
I haven't problems with the plotting itself. I have exactly the same distribution that I want. However, the plot shows only one part of the magnitude orders. The dataframe shows data at…
