DFF to DSF converter. Sound Quality

Sound quality: AuI ConverteR vs a converter software: DSD64 to DSD128 noise

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


In the ideal case, should not be noise in the audible band. Lesser noise (darker background) means a higher sound quality.


True Gapless Mode resampling albums (operas, live concerts, musicals, etc.) as a solid stream without artefacts on neighboring track borders. See the main software window  > Parameters tab.

True Gapless Mode

The pure signal on border of two neighbor tracks, when True Gapless Mode turned ON.

If tracks are processed as separate files at the track border artefacts (noise splashes) appears due to processing re-initialized at beginning of the track. To avoid it  all album tracks should be processed as a continuous stream without re-initialization.

In True Gapless mode, the converting software processes album tracks sequentially. Because to convert the next track, it needs to have processing state of the previous track.


Auto level normalization allows maximizing of loudness without overload.

Resampling can cause overload. Overload can cause distortions. Manual gain control can solve the issue. But auto level normalization makes it automatically and keeps your time.

AuI ConverteR is a configurable software that lets you choose the features you need and pay only for them. A "module" is a part of AuI ConverteR's functionality that you can buy separately. You can buy new modules later to enhance your Modula-R major version (details). Each module is a license key that you get by email and enter in the software. A "major update" is a change in the first version number of the software version (for example, from 10.x to 11.x) and it is not free. However, your license is unlimited-time, which means you can use the software as long as you want without any subscription fees. (details)

IMPORTANT: The Free version of AuI ConverteR does not work with any modules. You need to buy a CORE module first, and then you can add other modules that are compatible with it (details). If you buy all the modules, you get the same features as the PROduce-RD version, which is a complete and cheaper package. You cannot exchange your Modula-R license for a PROduce-RD license.
