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.

OFFLINE CONVERSION ADVANTAGES
Check offline pre-conversion advantages for music devices
Check offline pre-conversion advantages for mobile devices
Offline pre-conversion allows saving electrical energy and nature
If an audio resolution is changed during playback (inline conversion), this process consumes computing power and electrical energy. "Heavy" resolution conversion algorithms consume more computing resources and electrical energy. Also, additional energy for cooling is needed.
Offline pre-conversion is performed once. During playback, there is no resolution changing. And, electrical energy is not consumed for this processing.

WHY AUI CONVERTER
Pro vs "non-Pro" audio
AuI ConverteR is designed for the pro-audio market segment.
"Pro", "professional" means a secure use with minimum pitfalls.
You are just doing your job.
You needn't think about how well the converter works.
Its designers have already thought about it.
Why AuI ConverteR? Our conversion requirements
The main conversion aim is minimum impact on processed music. When audio resolution is changed, input and output should be the same as possible technically.
In instance, downsampling eliminates the high-frequency part of an audio spectrum. But the rest music data should be distorted minimally.
To avoid worrying about distortions for different conversion modes, conversion quality should be far beyond resolution requirements.
Conversion should be as "transparent" as possible.
AuI ConverteR: How the reliability is reached
An audio converter has numerous conversion modes: input/output combinations of sampling rates, bit depths, DSD/PCM modulations.
AuI ConverteR contains individual resampling filters for each of combinations of input/output sampling rates.
AuI ConverteR contains
1734 resampling filters = 17 input x 17 output sampling rates x 6 filter modes [linear optimized, non-optimized, non-optimized wide, G5 optimized, G5 transpose 440 to 432 Hz, minimum phase optimized].
For the best result, we carefully and manually minimize distortions as low as we're able for each of these filters individually.
It is more than 12 years of work and over hundred thousand experiments. And we continue the studies to find the best conversion ways.
Since the inception of the Audiophile Inventory, 5 resampling filter generations have been designed.
AuI ConverteR gives you several options for resampling characters (resampling filter modes). But, it is rather a matter of personal preferences than sound quality.
You just convert music and don't have to worry about the sound quality.
Read more about sound quality...
What determines the audio-conversion speed?
Resampling is a hard work for computers despite the apparent simplicity.
Conversion-time reduction is possible for more powerful computer's CPU.
First, we adjust sound quality (minimize distortions).
Conversion time may be reduced, but almost always at the sacrifice of quality.
If we can, we reduce the time.
Why AuI ConverteR Modula-R and PROduce-RD are not free or cheap?
We provide some conversion types without limitations in the free version.
However, the project is live. Permanent research and development, tech support are needed.
Operating systems alter. The modern versions impose new requirements.
The current quality level is time-consuming, and demands great effort and in-depth knowledge.
All these things are not free.
Paid licenses are the only source of our project funding.
When you buy the AuI ConverteR license, you help our project to exist and develop.
Only price comparison with pro-audio converter software is relevant.

SOUND QUALITY
See the background (noise floor) in the picture below. It is a tough case: conversion multibit PCM to DSD64. Lesser brightness of the background means better sound quality. In the ideal case, the tilted bright line (signal) should be at the black background.
EXAMPLE:
Marker at the spectrogram show the noise level at the marker point (upper edge of audible range). Compare values: -155 and -137 dB. AuI ConverteR provides a noise floor at the marker point about 18 dB better.
Sound quality comparison: AuI ConverteR vs a converter (PCM 352.8 kHz to DSD64)
Sound quality comparison: AuI ConverteR vs a converter (DSD audio file resampling)
The darker background indicates lesser noise. Lesser noise means higher sound quality.
Sound quality comparison: AuI ConverteR vs a converter software (DSD64 to PCM 44.1 kHz aliases)
In an ideal case, should not be repeatable lines with lower brightness. These lines show distortions in the audible range, which correlate with the original signal.
To reduce audible distortions in some audio systems (equipment and software), audio optimization may be applied at the user's choice.

SAVE YOUR BUDGET
Flexible price policy for purchasing and converter-ability upgrade.
You can get true studio quality without overpayment for excess functionality.
Look at minimalistic configurations, which you can expand in the future by ordering new functional modules.
To minimize budget we apply flexible price policy.
There are integrated editions with fixed functionality: FREE and PROduce-RD.
Configurable Modula-R edition allows assembling your configuration from modules. Each module provides an element of functionality.
PROduce-RD includes all functionality. It is the same complete Modula-R's module kit.
Modula-R allows ordering part of functionality (module or several modules) for a lower price than all-including PROduce-RD.
Example: To convert PCM to DSF/DFF, you can order [output D64/128] and [Base (core)] modules instead of PROduce-RD. Later, you can expand the functionality by ordering other modules.
PROduce-RD has a lower cost than the complete module kit of Modula-R.
Check typical Modula-R configurations >
Configure custom option kit >
If you forgot to order a module(s) or want to expand functionality: order module(s) later.
WARNING: Modula-R's modules are not compatible with integrated editions (FREE and PROduce-RD).

BRIEF COMPARISON BETWEEN VERSIONS
For AuI ConverteR, purchased major version number works without time limitations.
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.

PROduce-RD is like a discount for full module kit of Modula-R edition.
from -
Version number is X.y.z. X is major version number. Example: For version 10.3.4, 10 is a major number. Thus, major update is 9.y.z to 10.y.z to 11.y.z, etc.
Example: If you purchase Modula-R or PROduce-RD version 10.2, you have to pay for update to 11.0.
