FM Radcap PCIe – 6, 12, 18, 24 or 32 channels

The FM Radcap PCIe is a radio capture card designed for simultaneous recording of multiple radio stations. The frequency of each station is set in software and its audio appears as a standard Windows audio input device. RDS decoding is also supported.

The card uses a high-speed A/D converter to digitize the entire FM band, with up to 32 individual tuners implemented in a Xilinx Spartan 6 FPGA. Demodulated baseband audio is passed across the PCI Express link to the device driver, where stereo and RDS decoding is performed using the host CPU’s SSE-2 instruction set. This division of labour between the FPGA and driver allows greatest flexibility in catering for future baseband technologies while minimising the CPU overhead of the card.

A WDM driver for Windows XP (SP2 or later), 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. A programming API and DLL for software control and monitoring are also supplied.

The card is factory-configured for 6, 12, 18, 24 or 32 stations, but may be expanded in the field for an additional charge.

DAB+/DAB Radcap PCIe – up to four ensembles

MultiDABThe PCIe DAB+/DAB Radcap receives and decodes the entire contents of up to four DAB+/DAB ensembles, rendering each audio service as a virtual Windows audio capture device for use with multi-channel recording or monitoring software. Broadcast data services, including DLS text and MOT slideshows, are also available through a simple application programming interface.

The card supports both legacy DAB MP2 audio coding as well as the new HE-AAC v2 encoding used with DAB+ broadcasts.

The number of ensembles is factory-set as 1, 2, 3 or 4 but is field-expandable through a purchased expansion key.

Multiple cards can be installed, allowing simultaneous monitoring or recording of more than four ensembles.

A sample application is provided with the card, allowing monitoring of DAB+/DAB audio and data as well as providing diagnostic ensemble spectrum displays, signal quality indicators and an uncorrected error counter.

System Requirements

Platform: Windows Vista, Server 2008, Windows 7, Server 2008 R2, Windows 8, Server 2012 (32-bit and 64-bit versions supported)
(Note: Windows XP and Server 2003 are not supported)
Processor: 2GHz quad-core or better
Memory: 1GB minimum
Motherboard: PCIe socket, single lane or greater
Other: Sound card or motherboard sound port for monitoring

Specifications

Tuning range: Band III (174-240 MHz)
DAB format: Mode 1
RF input: BNC connector
PCIe interface: Single lane PCIe 1.1
Number of ensembles: Factory-configured for 1, 2, 3 or 4 ensembles (field-expandable for an additional fee)
Total number of services: 128
Error correction: Soft-decision Viterbi inner decoder, Reed-Solomon outer decoder
Audio decoding: MP2 and HE-AAC v2
Audio format: 48kHz 16-bit stereo
(other application sampling rates and bit depths supported through the Windows SRC)
(24kHz and 32kHz services are internally up-converted to 48kHz)
Decoding latency: 3 seconds

AM Radcap PCIe (max 32 channels)

The AM Radcap is a radio cature card designed for simultaneous recording of multiple radio stations (minimum of 2, maximum of 32.) The frequency of each individual station may be set in software and its audio appears as a standard Windows audio input device.

The AM Radcap uses a high speed analog-to-digital converter to digitise AM band, and then uses advanced digital signal processing utilising the MMX instruction set of PC’s processor to extract the audio for each individual station. It can be configured to either create a seperate audio stream for each station or to pair stations together as stereo streams.

A WDM driver for Windows 2000, XP and later versions is supplied as well software for setting the tuner frequencies and monitoring the received audio.

The card is factory-configured for 6, 12, 18, 24 or 32 stations, but may be expanded in the field for an additional charge.

Auricon 4.4 PCIe – analog, 8 mono/4 stereo in/out

auricon44
– 4 stereo balanced inputs and outputs configurable as 8 mono inputs and outputs
– 24-bit 192kHz A/D and D/A converters
– Simultaneous Record / Play on each channel
– Full Windows Wave, DirectX and Core Audio API functionality
– Supports Windows – XP, Server 2003, Vista, Server 2008, Windows 7, Server 2008 R2, Windows 8, Server 2012 (32-bit and x64 versions)

The Auricon 4.4 is a professional-quality audio input-output card designed and manufactured in Australia by Corporation Pty Ltd. It is supplied with a Windows WDM driver to provide full sound card functionality under Windows XP, Server 2003, Vista, Server 2008, Windows 7, Server 2008R2, Windows 8 and Server 2012.

The Auricon 4.4 has four stereo outputs and four stereo inputs. The inputs and outputs can be reconfigured as separate mono channels, giving eight inputs and outputs.

The card uses 24-bit 192kHz sigma-delta converters which pass data to and from the PC via a single lane PCI Express interface. An onboard FPGA provides audio buffering, level adjustment and mixing functions. Hardware sampling rates of 48kHz, 96kHz and 192kHz are available, with the Windows sampling rate converter transparently providing support for other rates. The software sampling rate and bit depth (32, 24, 16 or 8 bits PCM) can be set independently for each input and output channel. The Windows Wave, DirectSound and DirectShow API’s are supported, as are a variety of audio compression modes via the Windows Audio Compression Manager or other software compression systems. On Windows Vista / Server 2008 and later systems, the Core Audio API is also fully supported.

XLR Breakout lead

As the card comes standard with a 44-pin high-density D connector, Corporation offers an XLR Breakout lead for the Auricon 4.4. This lead is not automatically supplied with the card but can be purchased as an option. Should you require a breakout lead please specify when ordering.

Digitorc 4 PCIe – AES, 4 stereo in/out

Replacing the Digitorc M, the Digitorc 4 now has four AES 3 stereo channels on a Windows platform and is fully compatible with the Wave, DirectSound, DirectShow, MCI and Core Audio APIs.

At its heart is a Xilinx Spartan 6 FPGA, implementing both a single lane bus-master PCIe interface and four 24-bit AES3 codecs. Independent asynchronous sampling rate conversion on the inputs supports rates from 32kHz to 96kHz, while the output rate can be configured as 96kHz, 88.2kHz, 48kHz, 44.1kHz or 32kHz, either free-running or locked to an AES3 or AES11 reference on any of the inputs.

Software sampling rate conversion is automatically inserted by Windows when the application rate does not match the hardware rate. Software bit depths of 32, 24, 16 and 8 bits are supported on playback and recording. The mixer functions allow inputs to be mixed back into each output, while a digital loopback is available from each playback channel into its corresponding record channel.

High quality electrostatically-shielded transformers from Scientific Conversion are used on all the inputs and outputs.

Multiple cards may be installed in a single PC.
