Hello FASMers

Got a new question..

How can i generate sounds with FASM on a PC Speaker ?

e.G.

- a KICK Drum (very simple)
- a SNARE Drum (very simple)
- or a SAW synthie sound...

Please help me..

PS: I can give you webspace if you want

check http://www.codeproject.com/audio/MidiPorts.asp?df=100&forumid=4425&exp=0&fr=26

how about converting it to fasm source

sorry.. you havnt understand me..

i mean the INTERNAL PC SPEAKER which is on every pc´s board and produces the beep on the bootup post process..

Well, as far as I know, Windows provides very very few facilities for creating sounds on the PC speaker. Maybe a series of Beeps and Sleeps could work, but would be very complicated.

Here i made a simple test wich uses the windows beep command..

But its sh|tty ^^

You get less restrictive access to PC speaker in DOS (DVM also works fine). It's possible sequencing the basic notes to make some lo-fi midi-like tunes. The only problem is timing an appripriate delay, because it depend's on CPU clock. There was a nice DOS music player in some of the older topics @ wasm.ru, but it's not available now

wasm.ru says "due to anonimous (no one claimed responsibility) DDoS-attack made by unknown terrorists we had to move to another place. check within fortnight."



Does somebody know the new url ?

2 sylwek32:

It's not a mirror of the old wasm, but a new forum-centric project.

I found something interesting:
http://www.cubic.org/player/screenshot.html

It looks like a very promising engine, but I haven't tested it.
It should play MP3's propably on a PC speaker (which does the beeps)

It was (and perhaps still is) a really great player for DOS, however it didn't support PC speaker as an output.

I recall the Interia Player did support PC speaker output and was said to be 100% assembly code, however the source was never released to the public.

I'd suggest searching http://www.sac.sk (under /SOUND/) for something since they have lots of MOD player stuff, some with source, etc.

Or, try the following (no source, and I personally couldn't get to work):

Here's some nice library: http://www.programmersheaven.com/zone10/cat135/15982.htm (pure DOS only, however, and it seems to lack the complete sources).

As for Windows, there's a driver for Win95/98/Me that allows to play samples on PC speaker:

It's hard to find something with full source code, however.

@all:

Thank you very much for your help..

@rugxulo

Doesnt work
But thanks..

@tomasz:
the lib is nice , but i have no "c"

and i know the win driver...
but it hungs the pc..

Does somebody know a website where i can download C ?

2 sylwek32: Do you mean a C compiler? Which one?

Visual C/C++:
http://msdn.microsoft.com/vstudio/express/visualc/

Borland C++:
http://www.borland.com/downloads/download_cbuilder.html

GCC:
Well, It comes with Cygwin, AFAIR.

Intel C/C++:
Not free

Pelles C compiler :

also search for LCC (free c compiler)

P.S. FreeBASIC 0.16 has been released!

Can't copy any of the code there... IT has syntax errors and i don't know enough about ASM to edit out the syntax errors...

Hello, I was the poster of the mentioned FreeBASIC/ASM code. I basically borrowed from two websites. Maybe these will help. They only do simple beep with freq/duration, but perhaps you can modify them to work the way you want. Something to note though is that only admins on modern windows can do port access (without some hack), so in that instance i used the Beep function in the WinAPI.
