AudioScience Has Broadcast Tuner Adapters

AudioScience Has Broadcast Tuner Adapters

It’s a busy season for product launches. AudioScience Inc. checks in with two new eight-channel broadcast tuner adapters. These are intended for broadcast monitoring and logging, advertising verification and content identification.
The ASI8702 is a universal PCI card that contains eight AM/FM tuners. Each may be set to an independent AM or FM 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 high-speed bus master interface.
The ASI8703 is similar but contains eight FM/TV audio tuners that can access TV channels 2 through 69.
An RF connector on the card bracket supplies the signal to the tuners. Each has software-selectable attenuation of 0 or 20dB. A DB-9 connector supplies a line-level mono version of each tuner audio signal. The stereo signal is available from a 50-pin header on the board. A 225 MHz, 32-bit floating point DSP from Texas Instruments provides audio routing, processing and streaming. Eight stereo streams can be sent to the host PC for recording or analysis.
Driver support includes Windows 2000, Windows XP and Linux. Under Windows, both a low-latency WDM driver and traditional WAVE driver are available. Linux support includes the standard ALSA interface as well as the AudioScience HPI interface. The company said an open source Video4Linux driver is in development. Custom tuner configurations and DSP processing options are available. Info:
