Abstract

The paper describes the prototype of a broadcast media indexing engine based on a 64-point weighted-overlap-add DFT filter bank implemented in an FPGA. In its present configuration, the device simultaneously demodulates and displays a speech/music flag for 5 FM radio stations, with audio output routed to a loudspeaker via a user-operated switch. Extension to the full FM radio band will be possible using a larger FPGA.
