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.

Conversion sound quality: AIFF to WAV

AuI ConverteR has 2 output frequency bands by user option and according to the target audio file format:

  • "Optimized" / "Optimized G5" 20 kHz;
  • "Non-optimized..."
    [minimum among input and output sample rates]/2 (Settings > General > Filter mode);
  • "Non-optimized wide..."
    [minimum among input and output sample rates]/2 (Settings > General > Filter mode);
  • "Optimized G5" 20 kHz with shorter ringing length (lesser distortions).


Use minimum phase filter switch checked / unchecked to minimum / linear phase, respectively.
