To play back DSD (1-bit/2.8Mhz) on a Windows XP/Vista PC with Windows Media 10/11, click the following link to download a freely distributable plugin that Sony has developed. The plugin converts the DSD to PCM format in realtime as the DSD file is playing. If you have a good soundcard, you can play DSD files back in up to 24-bit/192KHz quality. You do need to have a PC with horsepower, at least a 3.0 GHz P4 or duo core PC.

1) About This Program
- By installing this program, DSD files (extension: *.dsf) can be played
on the Windows Media Player by converting the files to PCM format.
Note: Because a DSD file is converted to PCM format,
the audio quality is not the same as the DSD original audio quality.
Note: A VAIO computer that supports DSD playback can play DSD files
with the original audio quality.

3) Important Notes
- Installation
- When using Windows Vista
When you install the DSD to PCM Playback Plug-in on your computer
as a standard user, Windows will ask you to provide an administrator
password. In this case, enter the password.
- When using Windows XP
To install this program, you must log on to the computer using
an account with administrator privileges.
(For example, Administrator User Accounts.)
If you have logged on using a Limited User Account, log off
and log back on using an account with administrator privileges.
- If the DSD Playback Plug-in has already been installed,
This program cannot be installed.
- You do not need to install this program to a VAIO computer
that supports DSD playback because it can play DSD files
with the original audio quality.
- DSD Files Playback
- If the system requirements are not fulfilled, audio playback
may jump or not play normally.
- CD creation with Windows Media Player
- When adding DSD files, you can create a data CD using the writing function
of Windows Media Player. However, this data CD is not compliant with
DSD Disc specifications.
- Associating the DSF file extension with Windows Media Player

Windows Media Player will not be registered as the player for DSF
files (*.dsf).
To make Windows Media Player the default player for DSF files, right-
click a DSF file in Windows Explorer, select Properties from the
shortcut menu, and, in the window that appears, select Windows Media
Player as the program to open DSF files.
