To playback music at audiophile apparatus, save free space on hard disk, provide format compatibility, editing, you can rip convert SACD ISO to DSF, DFF (DSD audio files) [stereo, multichannel].
Also, you can optimize resolution of DSD file for discovering your DAC abilities.
Read the step-by-step manual on how to rip DSD ISO file.
How to extract SACD ISO to DSD (DSF, DFF) files [step-by-step]
AuI ConverteR give you ability of easy .iso file ripping. To convert SACD ISO to DSD (DSF, DFF files) on Mac or Windows in high quality, follow the steps below:
- Start AuI ConverteR 48x44 software.
- Push "Open files" button and select SACD .iso file.*
- Select DSF or DFF (DSD format) in the main window, Output panel.
.dsf format supports metadata (track, album, performer, album art, others)
- In the main window, Output panel: select sample rate up to 45.2 MHz [DSD1024]
(bit-perfect extraction at 2.8 MHz [DSD64] only) **
Read about sound quality and full converting ISO guide...
Also, look at how to choose output file's sampling rate...
- In the main window, Album art tab, assign album artwork **
- Select stereo or multichannel album variant of extraction from ISO.
- Select target directory. See more in the video and tutorial
- Push Start button to extract (rip) SACD ISO.
- Wait until the finishing of the conversion. Converted files are located in the target directory.
- If you got audible artifacts and distortions, it is an overload issue rather.
In Settings > General > "Output attenuator" field, set "-3 dB" or "-6 dB".
It is recommended to use automatical level normalization** (may not be applied for bit-perfect extraction) to maximize loudness and avoid distortions.
Also, manual gain correction** may be applied.
To solve various .iso-extraction issues, see the troubleshooting...
AuI ConverteR uses the best (by its developer's opinion) sound quality settings as default. Also, you can opt settings by your taste.
Also, read about SACD to DSD (optical disk ripping).
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 entire page carefully.

Why we use ISO to DSD file conversion?
To listening to SACD optical disk, special drive is used. As rule, computers are not capable to play back a Super Audio CD. However, the disk may be ripped to SACD ISO or DSF or DFF files.
SACD ISO, DSF, DFF are 1-bit DSD audio file types. To listening such files, digital-to-audio converter (DSD DAC) and player software is required. The audio player software should provide native DSD support.
Direct ripping to DSF and DFF files may cause some issues. DSF supports metadata (song and album info) better way than DFF. Extraction to DSF with some software may cause clicks at the file end.
SACD ISO files may include stereo and multichannel (5.1 surround) variants of the same album. Mobile phone or portable player have stereo output for headphones. Limited space of hard disk or SD-memory stick is used to excessive audio stuff that you don't listen.
You can extract either stereo or multichannel album variant to DSF or DFF audio files. Also, multichannel music may be downmixed to 2.0.
Back to top
SACD ISO is a container file with DSD tracks (songs) included in a music album. .iso file may contain mixes (variants) of an album: stereo and/or multichannel. Also, we can meet the similar DSD ISO term.
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 ISO to DSD extraction may be done 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, you can convert DSD ISO to .dsf/.dff files with resampling in extraction. 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 of converter SACD ISO to DSD.
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:
- Filter mode list:
- "Optimized resampling filter" cut frequencies upper 20 kHz (eliminating intermodulation distortions that ultrasound generates);
- "Non-Optimized resampling filter" cut frequencies upper 20...24 kHz (depend on input/output sample rates) - eliminating intermodulation distortions by ultrasound, wider signal band;
- "Non-Optimized wide resampling filter" cut frequencies upper 20...100 kHz (depend on input/output sample rates).
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.

How to save disk space and energy at portable devices
SACD ISO files may contain 2 album variants: stereo and multichannel.
Portable devices (DAP, mobile phone) have:
- limited hard disk space;
- limited battery charge (time of autonomous work).
As rule, portable device is intended for stereo playback.
An audio player software has 2 options:
- extract stereo album variant from SACD ISO;
- extract multichannel (5.1) variant and downmix it to 2.0.
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):
- Push "Open files" button and open .iso (sacd iso only).
- In AuI ConverteR's main window > Source files table, click mouse on ISO file row.
- Track window appears. Information about the SACD ISO is shown there.

- If such conversion software item works in bit-perfect mode and without glitches, there is no difference for sound quality.
- If resampling or any audio processing (gain, filtering, EQ, etc.) is there, it can cause a sound quality difference.
- When ISO is extracted, an output file may be named according to the text ISO metadata. If the metadata are too long, file path+name length may be excessive for an operating system.
Also, the metadata can contain non-Latin or forbidden symbols (*, ', etc.). These things cause (can cause) error. And extracted audio file cannot be created.
For example, AuI ConveteR fix these issues automatically.
