Key click sound

John_Schofield · Post by **John_Schofield** » Thu Oct 04, 2007 12:30 am

Does anyone have a code snippet which would generate a click sound each time a key is pressed when typing a string of characters?

I can make a beep when I press "Enter" or but I'd like to be able to hear a click each time a key is pressed as a string is built up as well.

Is that possible?

Cheers!

Hello again John.

This is probably not what you want but the best I have come up with so far:

Code: Select all

CLS

DO
a$ = INPUT$(1)
  PLAY "T255 L64 g-"
  b$ = b$ + a$
  LOCATE 1, 1: PRINT b$
LOOP

Note that the loop is closed, leave it up to you to sort out an appropriate exit. You can also adjust the speed and key to suit.

Regards

Valerie.

Thanks Valerie

Much appreciated.

I have another solution I thought of last night so I'll try them both!

Hello, Valerie. I don't know why the PLAY line didn't respond for me. I changed that line to
SOUND 255,1
and that worked well.

Hello Ralph.

I don't understand why Play didn't work for you either. I'm getting the click thru' my soundcard not from the inbuilt speaker.

I had tried Sound before posting but thought that Play was a tad faster, am probably wrong on that. Also Play gives me more of a click than a tone.

Beep also works for me but is only good for very s-l-o-w typing.

BTW am using QB 4.5 in XP Home cmd.exe although Command.com made only one difference, that being that Beep no longer worked.

Regards

Valerie

I've found that Valerie's PLAY instructions gives a pretty quiet click which is ok with a silent keyboard but not my clacky old thing here at home - the keys make more noise!!

By experimentation, I've settled on SOUND 950, .2 as being just about right for my particular requirement in a potentially slightly noisy enviromnent. If I need to make it more audible I just extend the duration to .5 or something and/or slightly reduce the frequency.

Both come out through the built in speaker rather than the sound card, which fits the bill for me.

I've managed to squeeze the SOUND instruction into a section of code I found in an old program which builds a string from key presses so this works fine for me now.

Thanks for your help.

Thanks for your response John. As I now am using XP perhaps that has something to do with the soundcard being used. Adjusting the Volume control allows for quiet or deafening clicks.

Glad you found a solution which suits your purpose.
