Those who enjoy radio but don't like listening to advertisements might want to look at a unit from PopCatcher, a Swedish audio designer. Its FM radio system turns radio broadcasts into MP3s, leaving out talk and advertising. The self-learning PopCatcher software separates music from DJ conversation and commercials, automatically saving songs as separate music tracks. Those tracks are recorded at 192 kbyte/sec and stored in internal memory or a USB-connected MP3 player. The radio/recorder uses a Blackfin processor from Analog Devices for both DSP audio processing and control, eliminating the need for a separate device.
