How to convert SACD ISO to DSF, DFF (DSD audio files) [stereo, multichannel] to playback music at audiophile apparatus, editing and hard disk space-saving. Read the step-by-step manual on how to rip DSD ISO file.
To convert SACD ISO to DSD (DSF, DFF files) on Mac or Windows:
WARNING: AuI ConverteR 48x44 doesn't support DVD-audio and DVD-video.
AuI ConverteR processes too-long file names and paths, non-Latin and forbidden characters (created from metadata) for successful output file writing. Third-party utility decodes SACD ISO for additional processing with AuI ConverteR. Read the whole page carefully.
** If it's available in the purchased configuration
*** All prices on this page are in U.S. dollars without V.A.T. and other applicable taxes and fees. The prices are recommended. Information on this page is not a public offer.
For ISO tracks, DSF, DFF with lengths more 3 minutes FREE edition mute 2-second silence in the output middle
Converted stuff is placed in the target directory
Dithering is ignored when extracting ISO to DSF.
AuI ConverteR has several price/functionality options that allow saving your budget for the required functionality. You can expand Modula-R abilities later by purchasing new modules. Unlimited-time license, major updates (... 10.x > 11.x > 12.x > ... versions) are paid.

SACD ISO is a container file with tracks (songs) included in a music album. .iso file may contain mixes (variants) of an album: stereo and/or multichannel.
The file contains audio in 1-bit sigma-delta modulation with sample rate 2.8 MHz (a.k.a. DSD). The author hasn't information about higher sample rates in the .iso-file.
The container file's stuff may be extracted in bit-perfect mode. Both binary contents in the container and into extracted DSD files are identical. It is possible for 2.8 MHz (DSD64) sample rate only.
Equipment has several playback modes (audio resolutions), that can cause individual distortion level of each mode. Using of mode with minimum distortions can improve sound quality. Read details here...
Also, the DSD ISO content may be resampled in extraction to .dsf/.dff files. It allows playback of these files "natively" on DAC that is DSD128 and higher capable.
In the ideal case, should not be noise in the audible band. Lesser noise (darker background) displays higher sound quality.
We can compare noise with sea waves.
Lesser noise is like smaller quieter waves.
We can listen to music clearer when background wave noise is quieter.
A multichannel variant may be played back at a multichannel system or downmixed 5.1 in 2.0 to playback at stereo equipment or headphones.
Downmixing may be performed inline ("on fly" into a player) or offline. "Offline" means: convert ISO to DSF 2.0, with or without downmixing, before playback via a music converter. Offline stereo extraction/conversion saves disk space on hard disk of portable musical devices. Therefore you can place more music on a digital music player or mobile phone.
Also, read some sound quality issues below.
Conversion ISO to DFF is not recommended. Because DFF doesn't support metadata (song, album names, performer, year, artwork) standard way. Theoretically, metadata may be built into DFF technically as non-standard information block. However, playback software/hardware will ignore it, as rule.
If the target sample rate is D128 / D256 / D512 / D1024, resampling processing is used. Resampling processing based on filtering. These filters have several settings.
At Settings > General tab:
On some equipment "Non-Optimized..." filters can cause audible noise: watch the video.
"Optimized..." filter is recommended for most cases.
Check/uncheck Use minimum phase filter switch for minimum/linear phase filter respectively. "Non-Optimized..." filters have linear mode only.
SACD ISO files may contain 2 album variants: stereo and multichannel.
Portable devices (DAP, mobile phone) have:
As rule, portable device is intended for stereo playback.
An audio player software has 2 options:
In case #1, excessive hard disk space of mobile devices is consumed. And lesser music-file number may be placed on the mobile device.
In case #2, additional computing resources (and energy too) are consumed. Additional energy consumption reduces the time of autonomous work.
To solve cases #1 and #2, the extraction of stereo DSFs may be used.
If ISO contains a multichannel variant only, downmix 5.1 to stereo may be applied.
a) Don't open content of iso file that is mounted in a virtual drive. Open *.iso file with AuI ConverteR directly.
b) To view SACD ISO content (album name, performer, year, stereo/multichannel variants, track number):
DSF format is an audio file type that contains DSD stuff. Read details...
DSF is DSD audio file format.

If you rip SACD optical disk directly to DSF, it can cause issues of long path/name and others. Read more...
Yes. SACD optical disk and its ISO image are one of DSD audio files.
SACD may be converted to other DSD files without losses.
SACD is an optical disk that contains audio in DSD format.

You can open it:
SACD ISO may contains stereo and multichannel variants of an musical album. It consume additional space at hard disk. It is significant factor for mobile devices.
To solve the issue, stereo variant may be extracted or multichannel one is downmixed.
Also, sampling rate and bit depth may be matter for sound quality.
In a recording/playback audio system, DSD format allows passing some stages theoretically. So it may be a way to reduce distortions. However, the audio-system design is matter.
However, DSD causes some issues:
DSF files are DSD audio files.
You can burn DSF files on any size-capable optical disk with standard CD/DVD-burner.
However, these files will be visible at the disk as usual computer files.
To create SACD optical disk, special licensed equipment and authoring software (in instance, "Philips SuperAuthor") are need.

Yes, when you use bit-perfect extraction mode and target sample rate DSD64.
Multichannel extraction is recommended for multichannel audio systems only.
For stereo musical systems (especial portable ones) stereo extraction or downmix of multichannel to stereo is recommended. Read details...
No. If you use AuI ConverteR, select any target format, sample rate, bit depth once, without any intermediate conversions.
Yes. You can use batch ISO conversion with minimum AuI ConverteR configuration.
However, it must be remembered that batch ISO extraction demands many free temporary hard disk space.
You can set hard disk for temporary space in AuI ConverteR settings > Misc > "Directory of temporary files". After it's changed, restart the software.
Third-party sacd_extract codec or other utility, compatible with AuI ConverteR, connected as command line utility, decodes SACD ISO for further processing with AuI ConverteR. Read more about codecs...

SACD optical disk ripping cannot be read on an ordinary CD/DVD drive of a computer. The ripping requires special hardware to read a Super Audio CD.
To rip a SACD optical disk, the hardware is used in connection with sacd_extract utility, that may be configured for ripping via command line parameters.
The ripped DSD stream may be saved as .iso (SACD ISO) or .dsf/.dff files.
DFF files may cause issues with storing metadata.
DSD files in the ripping may cause issues with long path names and others. If using ripping software can't solve the issue, ripping to SACD ISO (.iso) files is recommended.
After it, ISO to DSF conversion may be applied...
