In depth
A closer look at DSPFIL
DSPFIL runs as a free programmable LOW/HIGH/BANDPASS FIR filter in the audio range 0-4kHz and is programmable in the fly in real-time. Sampling rate is 8000 samples/s. Lower/Upper-edge or width and center can be changed by the track bars. The graphic window shows the filter in frequency domain. The filter coefficients are calculated by a hanging windowed impulse response of a prototype Low Pass filter (sin(x)/x) followed by a frequency shift if necessary. Changing the filter is done by moving the track bars. If track bar is activated, the arrow keys allow adjustment by one Hz increment. Any change will update the filter in real-time.
