Newcastle, DE (April-5,2006) - AudioScience, a leader in professional sound cards for radio broadcast applications, has announced  the world's first broadcast sound cards utilizing the next generation PCI Express (PCIe) bus.

PCI Express is an emerging interface that uses serial data interconnects that run at 2.5Gb/s. The single lane PCI Express interface used in the ASI6600 series provides a peak throughput of over 200MBytes/s, almost double that of the older parallel 32bit PCI bus.

The ASI6600 series of sound cards takes the renowned ASI6000 series to a new level with a faster DSP, short-length PCI format, +24dBu analog levels, 96kHz sample rates and SSX multi-channel support.   All the features of the AudioScience ASI6000 range are also present such as MRX multi-rate mixing, MPEG Layer 2 and 3 encoding and decoding, TSX time scaling and SoundGuard transient voltage protection on all I/O.

Richard Gross, AudioScience President and co-founder said: "Take a look inside any new computer that you have purchased in the past 6 months.  Chances are it will include at least one PCI Express slot. The ASI6600 PCI-Express series can take advantage of these slots and shows our commitment to follow industry standards as they emerge and provide continuing innovation to the radio broadcast industry".

The ASI6644 and ASI6614 are the first products in the ASI6600 PCI Express range and include both balanced analog and AES/EBU digital I/O.  Four stereo inputs and outputs are provided on the ASI6644, while the ASI6614 has one stereo input and four stereo outputs.  Hardware sample rate converters are present on all AES/EBU inputs and a dedicated AES/EBU and Word Clock sync input are also standard.

SSX surround sound extensions (available in Q3'2006) will allow the ASX6600 series to play, record and mix audio streams with as many as 8 channels each, while utilizing the advanced ASI6000 series features of MRX multi-rate mixing and TSX time scaling.

The new series features driver support for Windows WAVE, DirectSound and Linux ALSA.  Developers may additionally use the AudioScience ASX and HPI development environments.

The ASI6644 and ASI6614 will be available in May 2006.  For pricing and further information, contact Richard Gross at +1-302-324-5333.
