The format was created by Digidesign, now called Avid, and is used with their Pro Tools software. SD2F files hold audio data and other information relevant in the Pro Tools application. It's also used for exchanging information between digital audio workstation (DAW) programs. Corel's Roxio Toast software can archive an audio disc as a Roxio Jam Disc Image file, and it uses the Sound Designer II Audio format to do it. This type of SD2F file is a full backup copy of the disc. Some Sound Designer audio files may use the SD2 file extension instead, most likely when used in the Windows version of the software. SD2 files, however, may also be Windows SAS 6.xx files.

How to Open an SD2F File

SD2F files can be opened with Avid Pro Tools or for free with Apple's QuickTime. Mac users can also open SD2F files with Roxio Toast. Any SD2F file you come across will most likely be a Sound Designer II Audio file, but if not you can try opening it with a free text editor to see the SD2F file as a text file. You can sometimes make out specific words within the file when it's opened this way, which you can use to help research the application that opens it. The SAS (Statistical Analysis Software) software suite from SAS Institute may use SD2 files, too, but only with v6 of the Windows edition. Newer versions use the SAS7BDAT extension and the Unix edition uses SSD01. See How to Change the Default Program for a Specific File Extension if you need help changing the program that opens SD2F files by default on your computer.

How to Convert an SD2F File

Avid Pro Tools can surely convert or export an SD2F file to a different format but we haven't tested this. In most programs, that type of feature is in the File > Save As or Export menu. It's unclear whether Pro Tools versions 10.4.6 and newer support the SD2F format, so it's possible that opening the file in a newer version of the software will automatically convert it to a different, newer file format. The Roxio Toast program mentioned above supports saving SD2F files as BIN/CUE files. You can then convert those BIN or CUE files to the more common ISO format. Something else you can try is the free SdTwoWav tool to convert the SD2F files into WAV files, but you may have to rename them to have the .SD2 file extension since that's what the program recognizes. If you're on Mac, you can convert SD2F files to the AAC audio format with Finder. Right-click one or more SD2F files and choose Encode Selected Audio Files. TechJunkie has some more instructions on doing this. Once you get your SD2F file to exist in a different format, it might be able to be used with a free file converter. For example, if you manage to convert SD2F to WAV, an audio file converter can convert that WAV file to a number of other sound formats.

Still Can' t Open Your File

Some files share a similar looking file extension and can easily be confused for an SD2F file. If you can't get your file to open using the programs mentioned above, double-check the file extension to make sure it ends with .SD2F. SDF is one example where the suffix belongs to SQL Server Compact Database files, not an audio format. You can't open an SDF file with the programs mentioned on this page, and neither do SD2F files work with Microsoft SQL Server. eD2k, which stands for the eDonkey2000 network, is another example where a similar abbreviation has nothing to do with SD2F files. So, too, are DS2 (Olympus DSS Pro Audio) and D2S (Diablo 2 Save) files. If you find that your file isn't really in the Sound Designer II Audio file format, or any of these other formats that use the .SD2F extension, take note of the suffix your file is using. Use that file extension as a way to search for more information on the format it's in, which should help you discover which programs can open or convert it. FAQ When did Avid buy Digidesign?
