    3.  Acknowledgement


1. ENVIRONMENT VARIABLES

   There are three environment variables used to signify information
   of our Sound Blaster cards: SOUND, BLASTER and MIDI.  These
   variables will be setup during your Sound Blaster installation.

   SOUND environment variable

   The SOUND environment variable specifies the directory location of
   Sound Blaster 16 drivers and software.  The command for setting
   the SOUND environment variable is as follows:

             SET SOUND=<path>

     Note that there is no space before and after the = (equal) sign.

   BLASTER environment variable

   The BLASTER environment variable specifies the base I/O address,
   interrupt number and DMA channel hardware configuration of the
   Sound Blaster 16.  The command for setting the BLASTER environment
   variable is as follows:

             SET BLASTER=A220 I5 D1 H5 P330 T6

     Where:
            A  Specifies the Sound Blaster 16 base I/O port
            I  Specifies the interrupt request line
            D  Specifies the Low DMA channel
            H  Specifies the High DMA channel
            P  Specifies the MPU-401 base I/O port
            T  Specifies the card type

     Note that there is no space before and after the = (equal) sign,
     but there must be at least one space between two settings.

   MIDI environment variable

   The MIDI environment variable specifies the MIDI file format used
   and where the MIDI data is sent to.  The MIDI data can be sent to
   FM chips or MPU-401 port.  Generally, there are three MIDI file
   formats available in the market, General MIDI, Extended MIDI and
   Basic MIDI.  The command for setting the BLASTER environment
   variable is as follows:

             SET MIDI=SYNTH:<1/2> MAP:<G/E/B>

     Where:
            SYNTH:   1  Specifies internal synthesizer (default)
                     2  Specifies MIDI port

            MAP:     G  Specifies General MIDI file format
                     E  Specifies Extended MIDI file format (default)
                     B  Specifies Basic MIDI file format

     Note that the MIDI port refers to MPU-401.


2. MAXIMUM RECORDING RATES FOR SOUND BLASTER 16

   The sampling rate used for recording is largely influenced by your
   computer's main  processor.  To obtain 16-bit digital audio using
   Windows, the following maximum recording rates are suggested.

   To obtain optimal performance, try  configuring the sound card to
   use a 16-bit DMA (Direct Memory Access) channel under Windows.
   Refer to your Sound Blaster 16 Getting Started Manual for more
   information on setting up the sound card to use a 16-bit DMA
   channel.
