How to convert SACD_ISO files to DSF format

Assuming you have a Windows environment

You will need to download and install the Oracle Java Runtime Environment (64-bit) as a prerequisite, unless you already have it.

The tool used to extract .dsf is called SACDExtractGUI, it is a Java applet, so you must install Java first before trying to run SACDExtractGUI.

The actual extraction application for Windows is called sacd_extract.exe, download the latest -107 version (scroll to the bottom of the page to reveal the assets), unzip if necessary, and place it in the SACDExtractGUI folder.

Launch SACDExtractGUI by clicking the .jar file. With Windows you might need to right-click it and choose Open with -> Java.

Once launched you need to specify the path to the sacd_extract.exe file in the Program field using the Browse button (overwrite what is pre-populated in that field).

Select the File radio button in the Input field, and use it's Browse button to locate and select the ISO you wish to extract from.

Select DSF and either Stereo, Multi-channel, or both in the Processing field.

Select an Output directory in the Output field for where you wish to write the extracted .dsf files.

Run the extract.

Jriver will play as well as convert the SACD ISOs.

Thanks for the responses.  I am in a Mac environment.   I opted for Audirvana which with changing one setting therein, my SACD-ISO files play just fine, evidently converted to DSD64 files which sound fantastic to my ears.  The move to Audirvana took no time at all and my sense is that the music via Audirvana has a bit more sparkle than via Roon.  Roon's meta-data is clearly superior, but I can live without that.  

I have been vexed with this conversion process I had with my post, but it is now unnecessary and I now have access to over 1,000 recordings that I had not previous been able to hear.  I am super happy.  Whitestix
