ASI 6640
Product Description
Built for Broadcast
The Audioscience ASI6640 is a professional grade PCI-Express sound card designed for use in radio broadcast automation and audio production.
Providing 12 play streams that are mixed to 4 balanced stereo outputs and 8 record streams fed from four balanced stereo inputs, the ASI6640 features AudioScience's unique "anything to anywhere" mixing and routing.
A choice of uncompressed PCM, MPEG layer 2 and MP3 is available for both recording and playback. All compression is handled by an on-board floating point DSP, allowing the host computer to focus on other tasks.
ASI6640 functionality includes MRX multi-rate mixing technology which allows streams of different sample-rates and formats to be mixed digitally. TSX time scaling allows compression/expansion of any or all playback streams in real time with no change in pitch.
For emerging surround sound applications, SSX mode allows multichannel streams of up to 8 channels to be played, recorded and mixed.
New computers typically include more than one PCIe slot. Responding to developments in PC Hardware, AudioScience now provide additional product configurations for new PC platforms with the ASI6600 series. The new series features driver support for Windows WAVE, DirectSound and Linux ALSA.
Developers may additionally use the established AudioScience ASX or HPI environments that have proved to be highly sucessful when interfacing previous products.
