SOUND BLASTER AWE32 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 AWE32 3. Additional information on Sound Blaster AWE32 4. 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 AWE32 drivers and software. The command for setting the SOUND environment variable is as follows: SET SOUND= 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 AWE32. The command for setting the BLASTER environment variable is as follows: SET BLASTER=A220 I5 D1 H5 P330 E620 T6 Where: Axxx Specifies the Sound Blaster AWE32 base I/O address. xxx can be 220, 240, 260, or 280. Ix Specifies the interrupt request line. x can be 2, 5, 7, or 10. Dx Specifies the Low DMA channel. x can be 0, 1, or 3. Hx Specifies the High DMA channel. x can be 5, 6, or 7. Pxxx Specifies the MPU-401 interface base I/O address. xxx can be 300 or 330. Exxx Specifies the Advanced WavEffects chip's base I/O address. xxx can be 620, 640, 660, or 680. Tx Specifies the card type. x must be 6. 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 Sound Blaster MIDI 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: MODE:<0/1/2> Where: SYNTH: 1 Specifies internal synthesizer (default) 2 Specifies Sound Blaster MIDI port MAP: G Specifies General MIDI file format E Specifies Extended MIDI file format (default) B Specifies Basic MIDI file format MODE: 0 Specifies General MIDI (default) 1 Specifies Roland Sound Canvas 2 Specifies Roland MT32 2. MAXIMUM RECORDING RATES FOR SOUND BLASTER AWE32 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. ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÑÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ» º SYSTEM ³ RECORDING RATE º ÌÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍØÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ͹ º ³ º º 386 and above ³ Stereo - 44KHz º º ³ Mono - 44KHz º º ³ º ÇÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÅÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄĶ º ³ º º 386 SX and below ³ Stereo - 22KHz º º ³ Mono - 44KHz º º ³ º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÏÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ To obtain optimal performance, try configuring the sound card to use a high DMA (Direct Memory Access) channel under Windows. Refer to your Sound Blaster AWE32 Getting Started Manual for more information on setting up the sound card to use a high DMA channel. 3. ADDITIONAL INFORMATION ON SOUND BLASTER AWE32 a. The QSound effect type is slightly softer in volume when compared to the reverb/chorus effect types, so you might want to turn up the volume while utilizing QSound effects. b. The AWE32 Control Panel allows you to experiment with QSound panning. Lets say you have a piano track playing in MIDI Channel 1, and you are currently using the QSound effect code. Activate the BOB dialog box of the control panel, and assign controller 10 ( MIDI PAN ) to channel 1. Make sure that the 'M' checkbox is checked. When you move the slider for channel 1 you will experience the piano sound being panned spatially. 4.
