High performance Digital Signal ProcessorThe high performance Digital Signal Processor technique, realized with the SHARC® ADSP21369 from Analog Devices, offers a unique filtering used in the High End audio world for the first time. Using the „Fast Convolution” arbitrary frequency slopes can be generated for multi channel too and in real time. |
Digital filtering using „Fast Convolution“
Handling the „Fast Convolution” is done by converting the audio signal from time to frequency domain (FFT), processing the wanted filter function and converting back to the time domain again (IFFT). This processing allows filter functions never to be achieved by any analogue technique and with digital filtering only at low sampling rates.
