Convert ISO (aka SACD ISO) to DSF, DFF (DSD audio files) [stereo, multichannel] to playback music at audiophile apparatus, editing and hard disk space-saving. Read step-by-step manual.
To convert ISO to DSD files:
WARNING: AuI ConverteR 48x44 don't support DVD-audio and DVD-video.
AuI ConverteR process too long file names and paths, non-Latin and forbidden characters (created from metadata) for successful output file writing
* If .iso supported in the purchased configuration. When you convert first time read about (auto codec downloading and installing).
** If it's available in the purchased configuration

WARNING: ISO (1-bit audio, aka SACD ISO only), DSF, DFF are supported in price configurable Modula-R and all-included PROduce-RD
For ISO tracks, DSF, DFF with length more 3 minutes FREE demo mute 2-second silence in the output middle
Converted stuff is placed in the target directory
Dithering is ignored when extracting ISO to DSF.
Select target format to convert ISO to DSF
Album artwork panel
SACD ISO is file-container with tracks (songs) included in a musical album. The file-container may contain mixes (variants) of album: stereo and/or multichannel.
The file-container has sample rate 2.8 MHz and bit depth 1 bit sigma-delta modulation / DSD (the author have no information about higher sample rates in the containers).
The file-container's stuff may be extracted in bit-perfect mode (without altering). There is binary content the container and extracted stuff is identical. It is possible at 2.8 MHz sample rate only.
Also, the container's stuff may be resampled so that playback at D128 and higher DAC or digital music player. Equipment has several playback modes (audio resolutions), that can cause individual distortion level of each mode. Using mode with minimal distortions can improve sound quality. Read details here >
Sound quality: AuI ConverteR vs a converter software: DSD64 to DSD128 noise
In the ideal case, should not be noise in audible band. Lesser noise (darker background) is higher sound quality.
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 player) or offline (convert ISO to DSF 2.0 - with/without downmixing - before playback via music converter). Offline stereo extraction/conversion save disk space at portable musical device's hard disk. Therefore you can place more music at 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:
At some equipment "Non-Optimized..." filters can cause audible noise: see 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 at the mobile device.
In case #2, additional computing resources (and energy too) are consumed. Additional energy consuming reduce autonomous-work time.
To solve cases #1 and #2, the extraction of stereo DSFs may be used.
If ISO contains multichannel variant only, downmix 5.1 to stereo may be applied.
a) Don't open content of mounted iso file. Open *.iso file instead.
b) To view ISO content (album name, performer, year, stereo/multichannel variants, track number):
SACD ISO is DSD audio file, that is image of SACD optical disk. Read more...
SACD optical disk may be converted to DSD files directly.
However, file name is formed by metadata. It can cause file-creating error due to:
In this case you can convert the optical disk to SACD ISO and extract DSD files with auto fixing of these issues.
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.
Sound quality of SACD ISO to PCM extracting is defined by implementation. So, qualitative extraction may be used for further bit-perfect PCM playback.
Also, sampling rate and bit depth may be matter for sound quality.
SACD optical disk may be ripped to SACD ISO. SACD ISO may be extracted to FLAC.
SACD ISO may be extracted to:
DFF file is DSD file by Philips. As rule, it used in pro-audio applications. Have DSF-format-identical sound quality.
To rip SACD optical disc, some hardware is need. See details by links below...
See DSF to FLAC user manual...
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...
Read recommendations for target sample rate choice...
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 minimal 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.
