The AstoundSound Expander is a software application that runs on your Macintosh or PC. Expander is always running in the background processing audio from all applications.

It takes any stereo audio as input and produces a significantly wider stereo image, while preserving center information (e.g. vocals or center staged instruments), in real time.

The result is a wider, fuller and richer listening experience that can be heard while playing music, a movie, a video game or any application that produces audio.

AstoundSound Expander Features:
1. Expander runs on Macintosh and Windows, and activates through any application that produces sound. For Leopard/Snow Leopard/XP/Vista/Win-7
2. Virtual audio device driver capturing & processing all audio in real-time.
3. Optimized processing for better CPU & memory usage.
4. User Interface control allows you to switch listening modes on demand. Meaning you can adjust from settings that are made for music, movies and games, each with its own slider.
5. Keyboard short-cuts allow you to switch between listening modes and are customizable.
6. Preamp increases or decreases input gain, reducing the possibility of distortion without losing any audio quality. So you can enjoy a rich, fuller sound experience, with every part of the sound remaining crisp and clear.

You can hear the AstoundSound effect through your computer's built-in stereo speakers, headphones or external stereo speakers connected to your computer.

Another fun way to hear AstoundSound is to connect the line-out (headphone) jack of your computer to an available input on your home stereo receiver.
