True Gapless Mode

True gapless mode is intended for albums, that should sound like as a solid stream. It is live concerts, operas and others. After resampling at track borders, artifacts can appear. It happens due to processing re-initialization at the begin each track. In True gapless mode, initialization is performed at begin of the first album track.

If True Gapless Mode is turned on, album tracks are converted sequentially, one-by-one. There is information about end of previous track. It needs before starting processing of the next one.

Auto level normalization

As rule, 1-bit records have -6 dB headroom by sigma-delta modulator stability issues.

Auto level normalization allows maximization of album level with keeping relative levels of its tracks. Also, the levels may be normalized by average value.

Sound quality

Sound quality (distortion value) is the first point of attention in design professional software. Transformations to the original stuff should be quality-transparent as possible.

AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz aliases

AuI ConverteR vs a converter software: DSD64 to PCM 44.1 kHz

 

In the ideal case, should not be repeatable lines with lower brightness (aliases). The aliases are audible distortions, that correlate with the original signal.

Any AuI ConverteR’s version provides fully identical signal processing quality.

But functional restrictions and available formats, sample rates, etc. are different.

The software converts DFF audio file to FLAC as sigma-delta-modulation noise filtering.

Operas, musicals, live concerts and the same albums are solid music streams. Such recordings are done in a single file. Before placement at optical disk, the stream is divided into tracks. At their borders, non-zero loudness is possible. It can cause border artifacts.

Converting such tracks as separate files, cause aftifacts at track borders. Because processing is initialized at begin of the next track. True gapless conversion process these tracks as a 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 magnifies or reduces, in some cases, loudness of all tracks so maximal peak level of full converted album is 0 dB or all tracks have the similar loudness.

Resampling filters of the conversion software are reviewed here.
