PC Audio + Tuner Cards

AudioScience DSP based digital audio peripherals for the broadcast, installed sound and entertainment markets.

We offer a complete range of high performance PC audio cards for professional audio applications. In addition, a number of special purpose cards have been developed for radio logging, TV reception and store-casting. Drivers are available for Windows®, Linux and Mac OS, plus test applications for waveform mixing and signal generation.


One of the primary missions of AudioScience is to provide leading-edge digital audio solutions at the lowest possible cost. When designing its soundcards for increased flexibility, AudioScience uses the latest, most cost-effective DSP technology and compression algorithms to solve specific customer problems, such as how to provide multi-stream digital audio I/O on a PC platform.


In the professional environment, the digital audio files stored on hard drive come from an amazing variety of digital and analog sources including DAT, CD, the Internet, telephone patches, digital mixers and microphones and analogue sources, to name a few. AudioScience developed exclusive MRX Multi-Rate Streaming technology to create maximum flexibility in digital audio capture and playback.

This advanced technology allows the playback and mixing of stereo streams of MPEG Layer II & MP3 audio with different sample rates, while recording another stereo stream at a different sample rate. This AudioScience innovation offers more flexibility in the use of disk space while giving users increased performance in digital audio capture, playback and mixing.


AudioScience’s TSX time scaling technology can be used independently on any or all audio playback streams to expand or compress audio in real-time by up to 20%*, while preserving pitch and clarity. TSX can also be used in conjunction with any of the compression formats supported by ASI6000 adapters, including MPEG-1 Layer2 and MP3.

The algorithm is available to Windows software developers through the AudioScience wavX extensions to the Microsoft WAVE API, the AudioScience HPI interface. Linux developers are able to access it through the AudioScience HPI interface.

* While the settings range from ±20 percent, the extremes of that range will generally work with speech but not as well with music. ±10% should be used for music.


AudioScience offers easy-to-integrate products that provide enhanced digital audio functionality to users. In steering product development in new directions, AudioScience has created unique new technologies and processes that give its products increased functionality and compatibility.

Another benefit to users is the powerful mixing capability of AudioScience digital audio products. The ability to mix multiple streams to a variety of signal paths even if the streams have different sample rates brings heightened functionality to facilities that need more virtual mixing capability for on-air programming and broadcast production.

With field-proven drivers and Standards-Based Technology, AudioScience soundcards integrate seamlessly into nearly any computer-driven professional audio environment, and are compatible with the most popular broadcast software and hardware.
