- Fast Fourier Transform based Homogenization
- License: Shareware

Implementation of Fast Fourier Transform based Homogenization for heterogeneous materials dealing with electric or heat conductiviy. It takes the values of conductivity at regular grid of periodic unit cell that represents the material and produces the distribution of local fields such as electric field and electric current or temperature gradient or heat flux. The effective conductivity matrix is also produced. The algorithm works both in two and three-dimensional case..

- License: Freeware
- Price: 0.00

The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains. Many of our explanations of key aspects of signal processing rely on an understanding of how and why a certain operation is performed in one domain or another. This applet helps students feel comfortable with these explanations, helping to build a strong intuitive grasp of how signals in one domain correspond to signals in the other.
Students can load scanlines from common image patterns and see that scanline's Fourier Transform in real-time. For example, they can load the scanline of a standard test image to note how most of the energy is concentrated at low frequencies -- a key to why low-pass filtering doesn't render an image unintelligible.

Spectrum is a sound visualization effect based on FFT (Fast Fourier Transform) analysis. This effect is not exactly a scientific implementation but very useful to give visual feedback of the frequency components in playing sound in realtime. It is available for Flash (Player 9, ActionScript 3) and has very good performance. There are numerous parameters for easy configuration and simplified usage with your own Flash projects. You can even define new colors for the gradients..

- Xitona Guitar Tuner
- License: Shareware
- Price: 11.80

Pitch measuring accuracy much higher then usual software tuners based on fast Fourier transform (FFT). This software use special algorithm instead of FFT. Acoustic guitar strings tuning. High precession note pitch measuring. This simple software determining exactly pitch of your guitar strings, by using microphone and sound card. You can try it free of charge even without microphone. If you think you can tune your guitar exactly using only reference tones, you are poorly wrong. Theoretically, when you are using reference tones and the frequencies are roughly the same, a great resonance is produced.

- Calculate Wigner distribution

W = mywigner(Ex) W = output Wigner distribution Ex = Input electric field (MUST be a column vector Notes: W = Int(-inf..inf){E(x+y)E(x-y)exp[2ixy]} E(x+y) & E(x-y) are calculated via a FFT (fast Fourier transform) using the shift theorem. The integration is performed via a FFT. Thus it is important for the data to satisfy the sampling theorem: dy = 2*pi/X X = span of all x-values dy = y resolution dx = 2*pi/Y Y = span of all y-values dx = x resolution The data must be completely contained within the range x(0)..x(N-1) & y(0)..y(N-1) (i.e. the function must fall to zero within this range)..
