DSD Boss

Utility for decompressing DST encoded music files like SACD images

DSD Boss opens series of applications helping to manipulate with music DSD carrying format files. One of important operation is extracting and unpacking a DST encoded stereo track from a SACD image for the following playback of the result using such applications as Kamerton. On fly DST decoding requires huge computation resources which can issue a draining of a phone battery. (The problem isn't so serious for modern processors though). An extracted track is also taking less space in most cases than an original SACD image. Due high CPU consumption it is recommended to setup extraction tasks overnight when a phone is connected to an external power source. Typical extraction takes about 10 hours on 1GHz ARM processor and just about 20 minutes on an equal frequency i5. Therefore using the application is recommended only for cases when no a desktop computer is available for the same task.

Note if your OS Lollipop (Android 5.1) or later, then extraction path of files will look like

/sdcard/Android/data/rogatkin.mobile.app.dsdboss/files. A content of the directory will be deleted at uninstalling DSD Boss, so make sure you move all files from the directory to a safe location. It doesn't affect you if you rooted your device and removed a write protection Android storage.

For Android 11 and up, .iso and DSD files are invisible for ordinary applications as DSDBoss. There a simple trick to deceive Android. Add extension .mp3 to .iso, .dsf and .dff files preserving a

an original extension, for example my_music.dff file has to be renamed to my_music.dff.mp3. After that such files become visible and you can do all normal operations. Results will be stored in Downloads/Music.

Note that if your Android version is 13 or higher, then go to the general settings for the app and grant the permission to view audio files.
