The Radcap FM is a radio capture card designed for simultaneous recording of multiple radio stations. The frequency of each individual station may be set in software and its audio appears as a standard Windows audio input device. The card uses one 6-channel digital-down-converter chip, incorporating an on-chip A/D converter that digitises the entire FM band and digital filtering to extract each channel. The advanced driver software uses the processor's SSE multimedia instruction set to demodulate each channel and perform the stereo decoding. A WDM driver for Windows 2000, Windows XP, Server 2003 and Vista is supplied as well as software for setting the tuner frequencies and monitoring the received audio. RDS decoding is supported in the latest driver and API.
