Peter Swinkels Wed Nov 3 2021 at 5:34 am Recording and playing sound in Quick Basic
First the recording part:
Browsing through the sample code proviced on this website I found these snippets in "sndrec.asm":
mov dx,BASEADDR+00Ch
loopWait:
in al,dx
or al,al
js loopWait
ENDM
If I understand the code correctly, it is meant to ensure a consistent recording speed regardless of the CPU speed. Correct?
I also found this code at another website:
http://www.o-bizz.de/qbtuts/mallard/sbfaq.htm
I believe the examples provided there neglected to implement the speed control code posted above. Correct?
Now the play back part, this Quick Basic plays a single sample:
OUT CommAddr, &H10 'Give command to output a byte
OUT CommAddr, Byte(i) 'Output value
but there is no way to control the speed. How do I ensure samples are played back at a CPU independent speed?
