Sonifex Features Pro Sound, Radio Capture Cards at IBC

PC-DIG4 Digitorc 4 AES-3 Card

AMSTERDAM�Sonifex will feature a range of professional sound and radio capture cards at IBC 2014. These professional single lane PCIe cards have been precision engineered by Innes Corporation in Australia. Earlier this year, Sonifex bought Innes Corporation and as part of the purchase, a number of products transferred to Sonifex, including these high performance cards.

In the professional sound card series are the PC-DIG4 Digitorc 4 AES-3 Card and the PC-AUR44 Auricon 4.4 Analogue Card. Both offer audio performance and a complete set of drivers for PCs supporting Wave, DirectSound, DirectShow, MCI & Core Audio APIs.

The Digitorc 4 card has four AES-3 stereo input and output channels. 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. Files of any sample rate can be played through automatic software sampling rate conversion. Bit depths of 8, 16, 24 & 32 bits are supported for playback and recording. A 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. Electrostatically shielded transformers are used on all the inputs and outputs. Multiple cards may be installed in a single PC.

The Auricon 4.4 PCIe card is a 4 stereo input and 4 stereo output balanced analog PCIe audio card. The inputs and outputs can be reconfigured as separate mono channels, giving eight inputs and outputs. 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. Windows Wave, DirectSound and DirectShow APIs are supported, as well as Core Audio APIs.

The card uses 24-bit 192kHz sigma-delta converters that 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 card supports extended bit depths to 32 bit and 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 three radio capture cards are able to receive and decode a number of FM, AM and DAB/DAB+ channels simultaneously. They don�t have inputs and outputs, other than an aerial to capture the required signal and allow a PC to record or monitor a number of radio channels.

The PC-DAB1-4 Multi-Ensemble DAB/+ Radcap PCle 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. Since each ensemble can consist of up to 32 channels, a single card can simultaneously receive and decode up to 128 channels.

The PC-FM6-32 FM Radcap PCle is designed for simultaneous recording of up to 32 FM 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.

Similarly, the PC-AM6-32 AM Radcap PCle can simultaneously record up to 32 AM radio stations.
