Newcastle, DE - Sep 22, 2009 - Audio Science has received certification from Ibiquity for its ASI8914 four-channel HD Radio tuner adapter. The ASI8914 is a universal PCI card that contains four HD Radio/AM/FM tuners. Each tuner may be set to an independent analog or HD Radio station.

The audio from each tuner is presented to the computer host as a mono or stereo record stream that may be accessed through a 32-bit PCI bus master interface. Each tuner can also decode and stream the HD Radio program-associated data (PAD) data and RDS/RDBS data for analog FM. HD Radio multicast is supported, allowing the audio and PAD stream to be switched between the Main Program Service (MPS) and Secondary Program Services (SPS) under software control.

An F connector feeds RF signal from an external antenna to all tuners on the ASI8914. Each tuner may also be fed from an external antenna input. An HD50 connector makes available the mono or stereo line level audio of each tuner output. Recording formats include PCM, MPEG-1 layer2 and MP3. Using MRX, Audio Science's multi-rate mixing technology, each stream can be recorded at any sample rate between 8kHz and 48kHz.
