Losslessly Compressing DSD files with Wavpack
One of the biggest disadvantages of DSD files is their size. Most of the users who like DSD format, keep large SACD ISOs or split them to dsf/dff files. In both cases, the result is horrible space-wise as the majority of music albums need more than 1.5GB (only for the 2 channel files).
It was not long ago that Wavpack project came with a solution to the above: a lossless compression algorithm for dsf/dff files, resulting in up to 60% smaller files.
Understanding the use of DSD files with MPD
DSD, although a very old and failed technology, is again one of the hottest trends in computer audio. Below you will find a quick guide for MPD (Music Player Daemon) that will cover most of your needs: MPD and DSD with DoP Assuming that your DAC supports the DoP protocol, the only you need to do is to add the following line in audio_output section of mpd.conf:
dop "yes" Below you can see an example of this section:
How to convert SACD ISO to dsf/dff files
SACD ISO support in media players is not a popular feature, especially when it comes to Linux audio.
As of today the most popular solution is an MPD fork, a program not found by default in most of the Linux distributions (if you have an Archphile supported board however you can use the package I have created for that).
If you have this type of files and you can’t currently use them, the best solution is to convert them to separate dsf or dff files.
