DISCONTINUED AND REPLACED BY FM RADCAP PCI
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 four 6-channel digital-down-converter chips, each incorporating an on-chip A/D converter that digitises the entire FM band and digital filtering to extract each channel. A lower cost 6-channel version of the card, using only a single digital-down-converter is also available.
A WDM driver for Windows 2000, Windows XP, Server 2003, Vista, Server 2008, Windows 7, Server 2008-R2, Windows 8 and Server 2012 is supplied as well as software for setting the tuner frequencies and monitoring the received audio. The advanced driver software uses the processor’s SSE multimedia instruction set to demodulate each channel and perform the stereo decoding.
RDS decoding is supported in the latest driver and API.
