- SOUND BLASTER 16 README.TXT
- ===========================
-
- This file contains additional information to supplement the manual.
- Please read all the sections before you proceed with the installation.
-
-
- This file contains the following sections:
-
- 1. Environment Variables
- 2. Maximum Recording Rates For Sound Blaster 16
- 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.
-
- ╔═══════════════════════╤══════════════════════╗
- ║ SYSTEM │ RECORDING RATE ║
- ╠═══════════════════════╪══════════════════════╣
- ║ │ ║
- ║ 386 and above │ Stereo - 44KHz ║
- ║ │ Mono - 44KHz ║
- ║ │ ║
- ╟───────────────────────┼──────────────────────╢
- ║ │ ║
- ║ 386 SX and below │ Stereo - 22KHz ║
- ║ │ Mono - 44KHz ║
- ║ │ ║
- ╚═══════════════════════╧══════════════════════╝
-
- 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.
