- 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.
