This article describes hardware and software specifications for Microsoft Windows Sound System.


Windows Sound System is a 16-bit add-in audio card that takes advantage of Windows 3.1 audio capabilities. It adds new features to the audio applications in Windows 3.1, including limited voice recognition, which allows you to substitute voice input for some keyboard input. Windows Sound System uses OLE to paste sound objects into OLE-compliant applications. The ProofReader feature in Windows Sound System reads aloud the numbers in your Excel or Lotus spreadsheets so that you can verify the numbers without the aid of another person.

Minimum Hardware Requirements

  • An 80386 SX16MHz computer or higher with an enhanced graphics adapter (EGA). (A video graphics array [VGA] adapter is recommended.)
  • 640K conventional memory plus 256K extended memory. (2048K extended memory is recommended.)
  • A free 8-bit or 16-bit ISA or EISA expansion slot. (A 16-bit slot is recommended for hardware configuration flexibility.)
  • Microsoft Windows version 3.1 or later.

Board Specifics

Use the following connectors:
   1/8" microphone input (mono)
   1/8" line in (stereo)
   1/8" headphones out (stereo)
   RCA line out (one left, one right)
Use DMA channel 0, 1, or 3 (software selectable).

Use interrupt 7, 9, 10, or 11 (software selectable).

Use the following addresses:
   Synthesis: 388h (Adlib standard address. This address cannot be
   disabled or changed.)

   Digitized Wave Files: 530h, 604h, E80h, or F40h (jumper selectable).


Windows Sound System can use software capable of stereo recording and playback of digital (waveform) data at sampling rates of 11kHz (radio quality), 22kHz (tape quality), and 44kHz (CD quality). The digital waveforms can be recorded and played back in mono or stereo and in 8-bit or 16-bit format. With Windows Sound System, you can easily mix different formats. For example, you could mix a voice sampled with 8 bits at 11kHz with music sampled with 16 bits at 44kHz without converting formats.
