Our unique AudioPC Player has been designed in response to requests from analysts to make search and replay simple and easy. The graphically displayed data can be replayed synchronised together to reproduce an incident/scenario. The re-constructed incident/scenario can then be saved, instantly recalled, and burnt to a CD/DVD. Alternatively the data be merged with the recorded audio and exported into industry standard formats for replay in a standard Windows media player. No more time consuming problems associated with data location, synchronisation between data types or the need to re-record data for subsequent investigation.

Audio: AudioPC supports recording of audio data from a wide variety of different analogue interfaces at both conventional audio bandwidths of 3.4KHz and wide bandwidths of up to 37.5KHz. The solution offers support for both analogue and digital telephony inputs including ISDN E1/T1, digital PBX extensions (with D channel decoding) and analogue lines with CLI/DTMF decoding.

Screen Capture: AudioPC records operator’s screens by passively splitting the RGB or DVI video signal to the display. Data storage is minimised through the use of high quality codecs which provide compression ratios of up to 250:1 with no discernable degradation in quality. The recording of the screen is system independent and guarantees a faithful record of screen activity which can then be replayed synchronised with audio on a desktop PC.

Internet Protocol (IP): AudioPC can be used to record all standards-based IP and Voice-over-IP (VoIP) communications within a network and automatically log all call-related information. AudioPC is designed to ensure that no additional load is placed upon the IP network and can record multiple sites and VLAN’s and be scaled to support thousands of concurrent recordings.

Networks (e-mail and data): AudioPC records network data and its associated meta data by matching criteria such as IP addresses or port numbers. If the data is in a format such as RTP, the audio content may be played using AudioPC Player. Alternatively data such as e-mail or fax may be decoded and displayed.

Video - CCTV: AudioPC provides high quality lip synchronised digital CCTV recording for both PAL and NTSC in CIF, DCIF and 4CIF resolutions, with selectable frame rates up to 30 frames p/s. Features are motion detection, superimposition of date, time, logo and watermark information, capture to MPEG-4 format and Picture in Picture (PIP) format support with PTZ control.

Replay: AudioSoft’s unique AudioPC Player allows synchronised replay of all data types on a desktop PC. Secondary surveillance radar data can be replayed to either AudioSoft’s desktop replay console application or back into the radar system. CWP and audio data be selectively merged and exported into industry standard formats for replay in any Windows media player. Alternatively single channel audio data can be replayed through the web player within AudioPC Navigator.

Management: AudioPC Navigator uses Service Orientated Architecture (SOA) to allow all AudioSoft recorders to be remotely configured, controlled, monitored and administered from within a single easy-to-use web browser interface.
