- 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.
