I am a nearly complete Windows illiterate but who knows;
It's probably PCM with the PC speaker doing the low-pass filtering.
In the old day the Apple II had something like this saying "I'v got you"
(Yes I am "an old COBOL programmer with grey hair coming out of his nose")
BTW I hear hardly anyone use sound with CUSM. Is radio station
18.104.22.168 still in the air?
98% chance it won't work...
+ 4.7: How can I get sound from the PC speaker with WinMosaic?
This section explains how to install sound on a PC which already has a
working version of Mosaic for Microsoft Windows. Be warned in advance
that the results may be poor.
To get Mosaic to produce sound out of the PC speaker, first, you need
a driver for the speaker. You can get the Microsoft speaker driver
from the URL ftp://ftp.microsoft.com/Softlib/MSLFILES/SPEAK.EXE or by
doing an Archie search to find it somewhere else. SPEAK.EXE is a
self-extracting file. Copy the speak.exe file to a new directory, and
then type "SPEAK" at the DOS prompt. Do not put the file SPEAKER.DRV
in a separate directory from OEMSETUP.INF.
Now, you need to install the driver. In Windows, from the Program
Manager choose successively Main/Control Panel/Drivers/Add/Unlisted or
updated drivers/(enter path of SPEAK.EXE)/PC Speaker. At this point
some strange sounds come out as the driver is initialized. Change the
settings to improve the sound quality on the various sounds: tada,
chimes, etc. Click OK when you are finished and choose the Restart
Having installed the speaker driver, you will now get sounds whenever
you start Windows, make a mistake, or exit Windows. If you do not want
this, from the Main/Control Panel/Sounds menu, make sure there is no X
next to "Enable System Sounds."
Now, you need a sound viewer program that Mosaic can call to display
sounds. NCSA unfortunately recommend WHAM, which does not work well
with a PC speaker. Get the program WPLANY instead. You can find a copy
nearby with an Archie search on the string "wplny"; the current
version is WPLNY09B.ZIP. For details on archie and other basic issues
related to FTP, please read the Usenet newsgroup
Move the zip file to a new directory, and use an unzip program like
pkunzip to unzip it, producing the files WPLANY.EXE and WPLANY.DOC.
Then edit the MOSAIC.INI file to remove the "REM" before the line
"TYPE9=audio/basic". Then, you need lines in the section below that
read something like: audio/basic="c:\wplany\wplany.exe %ls"
audio/wav="c:\wplany\wplany.exe %ls" where you have filled in the
correct path for wplany.exe. The MOSAIC.INI file delivered with Mosaic
may have NOTEPAD.EXE on the audio/basic line, but this will not work.
Now, restart Mosaic, and you should now be able to produce sounds. To
check this, with Mosaic choose File/Local File/\WINDOWS\*.WAV and then
try to play TADA.WAV. Then, you might try the Mosaic Demo document for
some .AU sounds, but you are lucky if your speaker produces something
you can understand.
