AuI ConverteR 48x44 is DFF to FLAC converter (Mac OS, Windows) of audio files. For music production and hi-end home audio. In this article minimal price configurations are reviewed.
Read step-by-step guide below
To convert DFF to FLAC (DSD to PCM file):
Set output compression level:
Any compressing level provide same sound quality.
prepare music for:
computers,
digital audio players,
mobile phones,
media servers/streamers,
car stereo systems;
convert 1-bit audio stuff
for PCM DAC.
Multichannel and stereo
DFF D64 / 128 / 256 / 512 / 1024
FLAC 16 / 24 / 32 bit, 44.1 ... 352/384 kHz
Auto loudness normalizing
Uncompressed FLAC
True Gapless Mode
True gapless mode intended for albums, that should sound as solid stream. It is live concerts, operas and other. After resampling at track borders, artefacts can appear. It happens due processing re-initialization at the begin each track. In True gapless mode initialization is performed at begin of first album track.
If True Gapless Mode turned on, album tracks are converted sequentially, one-by-one. There is need information about end of previous track before start processing next one.
Auto level normalization
As rule, 1-bit records have -6 dB headroom by sigma-delta modulator stability issues.
Auto level normalization allow to maximize album level with keeping relative levels of its tracks.
Sound quality (distortion value) is first point of attention in design professional software. Tranformations should be transparently to original stuff quality as possibly.
AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz aliases
In ideal case, should not be repeatable lines with lower brightness (aliases). The aliases are audible distortions, that correlate with original signal.
Any AuI ConverteR’s version provide fully identical signal processing quality.
But functional restrictions and available formats, sample rates, etc. are different.
The software convert DFF audio file to FLAC as sigma-delta-modulation noise filtering.
Operas, musicals, live concerts and same albums are solid music stream. Recording is done in single file. Before placement at optical disk the stream is divided into tracks. At its borders non-zero loudness are possible. It can cause border artefacts.
Converting such tracks as separate files, cause aftefacts at track borders. Because processing is initialized at begin of next track. True gapless conversion process these tracks as single stream with initialization at first album composition begin only.
1-bit formats maximal value is -6 dB limited. It is DSD modulator's stability issues. Auto level normalizing magnify (or reduce in some cases) loudness of all tracks so maximal peak level of full converted album is 0 dB.
Resampling filters of the conversion software are reviewed here.
AuI ConverteR has several price/functionality options that allow saving your budget for the required functionality. You can expand Modula-R abilities later via purchasing new modules.
