MINIMUM PRICE OPTIONS
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.

detected errors, several times readings and comparing binary content
Displaying CD's audio stream errors
- Led indicate fatal or only probably recovered error via different colors.
- In error log table showed damaged tracks and its errors.
- For damaged track error locations on time axis are shown.
Recovering of damaged audio stream bytes

with unknown probability of correct restoring. - It give chance to get audio file from seriously damaged rare CDs.
AUDIO ABILITIES
- Bit-perfect ripping ability
to rip audio CD's binary content as is (except damaged data). - Studio quality of audio processing
- Auto loudness normalization and manual gain control
maximization to 0 dB of output peak levels without distortions. - Seamless album conversion
to converst albums without silence at borders (operas, live concerts, symphony,...) - Indication preemphasis of CD tracks
Remark: Some old CDs recorded with special pre-distortions of amplitude response.
CD player can restore track amplitude response to original by special pre-emphasis flag on CD.
After unproper copying CD can lost the flac.
Currently AuI ConverteR don't restore pre-emphasis.
In error log table showed pre-emphasis for tracks with it.
METADATA
Metadata of a music file is an information about performer, album, track names, artworks, others.
- Auto fill metadata (song name, album, ...) from free Internet CD database
for some CDs the database can provide multi language metadata choise - Assign album artwork before ripping
- Edit metadata in ripped files
including drag-and-drop of artwork - Artwork metadata management for ripped files
