Examples
Simple FFT demo
This demo shows how to work with FFT component. The program
generates the signal and fills the FFT buffer with the data. Then the
program calculates FFT and spectrum of signal. And finally, it displays
the input signal and spectrum using TChart component.
Simple IIR Filter demo
This demo shows how to work with IIR Filter component to
process realtime signal. The program generates a signal. The every
value of signal is passed through the filter. The input and output
values are displayed on the screen. Change the parameters of the filter
and you will see the changes of filtered signal on the chart.
IIR
Plot demo - Plot the frequency response of IIR filter
This
demo shows how to plot the frequency response of IIR filter. You can
change the parameters of filter and plot the frequency respomse on a
chart.
Perfomance
This demo calculates the perfomance of IIR Filter and FFT.
Simple spectrum analyzer
This demo shows how to calculate the spectrum of recorded
signal in realtime.
Simple player
This demo is simple sound player. This demo shows how to build a timbre
block, graphical equalizer and spectrum analyzer. The timbre block uses
IIR Filter components. The graphical equalizer uses FFT components and
FFT convolution method to filter signal. The spectrum analyzer uses FFT
components. Please see the source code of demos for more details.
