 
          ADVANCED SIGNAL PROCESSOR UPGRADE LATEST INFORMATION
          ====================================================

This file contains information not available during the printing  of
the manual.  Please read them before you proceed with any installation 
procedure.


This file contains the following sections:

  1. Software Installation
  2. Advanced Signal Processor
  3. Introducing QSound


1. SOFTWARE INSTALLATION

   The installation program, INSTALL.EXE will modify your CONFIG.SYS 
   file.  The original file will be renamed with a B~K extension.
   The original  file  WINSETUP.INF in your \SB16  directory will be
   renamed with a I~F extension.
   
   The procedure for installation is as follows :
   
   a.  Run the program INSTALL.EXE from DOS prompt and follow the
       instructions on the screen.
   
   b.  REBOOT YOUR SYSTEM.
   
   You will now be able to make use of the Advanced Signal Processor
   chip to perform various digital signal processing functions like
   data compression and decompression in real-time without making
   heavy demands on your system's CPU.

   Note : For those files that are being updated, the original copies
          can be found in the \SB16\BACKUP directory.

2. ADVANCED SIGNAL PROCESSOR

   All the CSP files (*.CSP) MUST be located in the Sound Blaster 16
   \CSP sub directory (example C:\SB16\CSP) when using any 
   compression technology.


3. INTRODUCING QSOUND

   QSound is a revolutionary sound placement technology that generates
   realistic and accurate sound spatial distribution.  With QSound,
   you can generate a 180-degree soundscape.  It is incorporated into
   the SB 16-Advanced Signal Processor audio card without any hardware
   addition or modification.  QSound requires only a traditional
   stereo playback system for reproduction.


   Setting Up Your Speakers for QSound

   To achieve optimum QSound imaging, you must take note of the
   following setup instruction.

   1.  Place the speakers on the same plane.  They must be placed at
       the same height and face you at the same angle.

   2.  Make sure that the speakers separation is between 16" and 72".
       When the speaker separation is 16", the listener should be at
       the center, about 20" away from the speaker plane.  As the
       speaker separation increases, the listener's distance from the
       speaker plane should also be increased proportionally.

       You may run QSALIGN.EXE to locate the optimum distance.

       If you are setting up your system in a small enclosed room,
       make sure that you place the speakers 3 feet away from side
       walls.

   3.  If you are using a hi-fi system, make sure that for both
       speakers you connect the red (positive) and black (negative)
       speaker wires to the respective positive and negative
       connectors of your amplifier.

   4.  If the speakers have separate volume control, set the left and
       right speakers volume level as equally as possible.  If your
       system has a single balance control, set it to the center or
       balanced position.

   5.  Adjust the speaker volume to a reasonable level.  If the volume
       is too high or loud, the reflected signal may neutralize the
       QSound effect.


   QSALIGN

   QSALIGN helps you align your speakers correctly.  To execute this
   program,

     - go to the QSOUND sub-directory (eg. C:\SB16\QSOUND ).
     - type QSALIGN, then press [ENTER].

   This program pans a sound source at the extreme left and the
   extreme right.

   To listen to the left playback, press the left arrow key. To
   listen to the right playback, press the right arrow key.

   After pressing each key, you should hear the sound source coming
   from a position outside the range of the two speakers.  With the
   speakers separation within the range of 16" to 72", you can
   continue to press the left or right arrow key, and adjust your
   distance from the speaker plane to find the sweet spot to achieve
   an optimum QSound image.

   Press the [ESC] key to quit from the alignment program.

   Note:   If you have set up QSound properly but are not able to
           hear the QSound effect, your speakers may be receiving
           out-of-phase signals.  Try again with another pair of
           speakers. If you are using a hi-fi system, make sure you
           have connected the speakers correctly.  (see Setting Up
           Your Speakers for QSound step 3)


   QSound in DOS

   Within the DOS environment, we have provided an auto running demo
     - QSDEMO.EXE.

   To execute this demo program,
     - go to the QSOUND sub-directory.
     - type QSDEMO, the press [ENTER].

   The demo program will first introduce QSound and then display a
   background picture.  Next, you will see an object appear randomly
   at different positions on the screen.  As the object appears at
   each position, you will hear the sound coming from that position.

   When the sound source is at the extreme left and right position,
   you will not see the object on your screen.

   Press [ESC] to end the demo.


   QSound in Windows

   In the Windows environment, we have provided a QSound Control
   Panel which allows you to use and experiment with QSound effects.

   To activate the QSound Control panel,
     - double click the QSound icon in the Sound Blaster 16 group.

   By default, the QSound effect is on (enabled) as indicated by a x
   in the QSound On check box.  Click on the check box to disable
   QSound. The x will disappear indicating that QSound is off or
   disabled.

   Note:   The QSound effect cannot be enabled or disabled during a
           wave playback.  Then enabling or disabling of QSound effect
           will only affect the next wave playback.

   The QSound Control panel is divided into two sections:
     - Left Output Channel to control QSound settings for the Left
       channel.
     - Right Output Channel to control QSound settings for the Right
       channel.

   Note:   For mono sound sources, use the Left Output Channel only.

   When using QSound Control Panel, you have the choice of manually
   setting the position of the sound source by dragging the respective
   Position Slider to the desired position.  Or, you can also use the
   Automatic Panning feature.

   To use Automatic Pan
     - click on the Automatic Pan drop-down list box.

   You have the choice of panning from Left to Right (L -> R), Right
   to Left (L <- R), sweep between Left and Right ( L <-> R) or switch
   off the automatic panning (click on None).

   You may change the automatic pan duration by clicking on the secs
   spin-button to increase or decrease the time.  Pan duration is the
   time taken to move from one end to the other.  If the time set for
   the automatic pan is less than the playback time of the sound
   source, the sound source will be at the final position of the
   automatic pan for the remaining time.

   Click the Quit button to close the QSound Control window.

   The QSound Control panel has a set of factory default settings
   when you first activate it.  All subsequent changes to the QSound
   Control panel will be saved as the new default upon your exiting
   the QSound Control panel.

   The QSound Control panel works in low priority mode. When an
   application such as Creative Mosaic uses QSound, the control panel
   becomes inactive.  When you quit the application that uses QSound,
   the control panel will become active again.


   Experiencing QSound in Creative Mosaic

   Our latest version of Creative Mosaic has been modified to support
   QSound.  As you move a tile to the left or right, the sound source
   will be coming from the extreme left or right respectively.


   Observing Some Tips When Using QSound

   Creative's QSound implementation supports PCM wave playback of 8kHz,
   11kHz, 22kHz and 44.1kHz only.

   Please take note that a normal stereo file having similar signals
   at the left and right channels, fully panned left or right, will
   not produce good QSound effect.

   Note : QSound effect only applies to digitized sound (*.WAV file)
          but not MIDI output (*.MID files) or CD output.
