Miles Sound System

RSX 3D Audio

What is RSX 3D Audio?

RSX 3D is an audio technology that allows two speakers or a set of headphones to produce true 3D positioning of audio samples. RAD acquired the RSX 3D audio technology from Intel Corporation in January 1999. It is now built into the Miles Sound System.

With RSX 3D Audio support, you can perceive sound from all possible directions -- not only the front and sides, but also above, below and behind. No additional hardware required!

The latest version of RSX 3D Audio is built directly into the Miles Sound System. You can now use all of RSX's 3D spatialization effects through the same Miles API that you've always used! The standalone version of RSX is no longer available.

New Features!

  • RSX 3D is now part of Miles!

    RSX has been built directly into the Miles Sound System. RSX 3D audio will be enhanced, updated, and supported inside Miles. Want to know more? Check out the Miles Sound System page!

  • True 3D Sound

    RSX 3D Audio features true 3D interactive audio using sophisticated, positional sound. Sounds actually seem to be positioned in 3D space. You can hear and distinguish sounds above you, behind you, to the left, and to the right.

  • Hardware Support

    Miles fully supports DirectSound 3D audio hardware accelerators.

  • Mixed 3D Audio

    Define your 3D effects on a per-emitter basis! Create sounds behind and in front of the listener simultaneously!

  • Scalability

    As your processor gets faster -- RSX 3D Audio sounds better! It detects the speed of your computer and tunes itself accordingly.

  • Open Speaker Cross-Cancellation

    Feel the audio pressing on your ears as truly realistic 3D sound comes to your speakers. RSX 3D Audio features transaural cross-cancellation technology. You can now get the same realistic 3D sound from your speakers that you hear with your headphones.

  • Doppler Effects and Pitch

    RSX 3D Audio will automatically calculate the change in frequency of a sound wave resulting from the relative motion of the sound source and the listener. Miles (with the integrated RSX 3D Audio) lets you alter the pitch of a tone to create effects like acceleration or fadeout.

  • Peripheral Optimization

    Headphones or speakers? It doesn't matter with RSX 3D Audio! Once you select your favorite audio peripheral, RSX 3D audio automatically tunes itself to sound its best.

Technical Support

RSX is built into other multimedia applications and games. If you are having trouble, then the first thing to do is contact the manufacturer of your application. RAD has never even seen 99.9% of the games that shipped with RSX - contacting the application vendor will almost always get you better and faster support.

If you are experiencing trouble with the sound specifically, try the suggestions in the next section. One of these suggestions will usually take care of sound problems.

If you are still having trouble, contact the application vendor and they should be able to get you going.

Sound Improvement Suggestions

There are three things you can try to improve your sound playback under Legacy RSX:

  • If you are running Windows 98, the problem may be corrected by reducing the amount of hardware acceleration. From Control Panel, select Multimedia | Audio | Advanced Properties (Playback) | Performance. A good starting suggestion is to change the hardware acceleration from Full to Basic.

  • Try changing your default device type from "directsound" to "wave". Do this by using REGEDIT.EXE to edit the registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Realistic Sound Experience\2.0\Device Type.

    Double-clicking on the device type field will open a dialog box that will allow you to change the value.

  • Try turning off MMX to enable higher-quality floating point spatialization. Do this by using REGEDIT.EXE to edit the registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Intel\Realistic Sound Experience\2.0\NOMMX.

    Double-clicking on the device type field will open a dialog box that will allow you to change the value. To turn off MMX, set this value to "1".

Uninstallation

If you want to uninstall RSX, the best way is to run the uninstaller from the "Add/Remove Program" icon in the Windows Control Panel. If you can't find the RSX uninstaller, then just delete " RSX*.* " from your \Windows\System directory to manually uninstall.
