This file is to demonstrate how to record and play simultaneously using
two Sound Blaster (or later) cards. The program create a delay by playing
back from a file about 1 second after the recording of that file started.
This zip file contains:
DELAY.C Delay program for two Sound Blasters.
DELAY.EXE
SBDEFS.H Header files for compilation.
MYDEFS.H
DELAY does an 8-bit recording to disk. Approximately one second after the
recording was started, the playback starts from the same file. After you
run this program, you might want to delete the DELAY.RAW recording file.
BEFORE RUNNING DELAY.EXE:
You should already have a BLASTER environment variable for your primary
card (e.g. BLASTER=A220 I5 D1 T3). Make a BLASTER2 environment variable
that specifies the configuration of the second Sound Blaster card (e.g.
BLASTER2=A240 I7 D3 T3). The two cards must be configured for different
I/O port addresses, different IRQ numbers, and different DMA channels. The
primary card (BLASTER) does the recording. The secondary (BLASTER2) does
the playback.
Make sure the microphone recording level on the primary card is turned up.
