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.

 

Offline pre-conversion allow to save electrical energy for resampling calculations and lesser cooling intensity to save nature

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

 

Sound quality is primary goal

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 PCM 352.8 kHz to DSD64

 

Sound quality comparison: AuI ConverteR vs a converter (DSD audio file resampling)

Sound quality comparison: AuI ConverteR vs a converter DSD64 to DSD128

 

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)

Sound quality comparison: AuI ConverteR vs a converter DSD64 to PCM 44.1 kHz

 

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

 

AuI ConverteR Modula-R. Flexibly configurable audio converter

 

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).

OPINIONS

 

Roland Krammer, Managing Director, Crayon Audio GmbH, AuI ConverteR 48x44 since 2012

...we use AuI ConverteR 48x44 software, so that we can provide right examples...

...The dither generated music data that sounded more fine then the original...

Theo G. Köhler, owner RecordingMediA, AuI ConverteR 48x44 since 2016

...The samples were given to three different people all well known in the music industry; 2 music directors (Choir and Orchestra) and 1 sound engineer. Their comments were very enthusiastic and confirmed what I was hoping for; the software you have developed is an excellent peace of work and a very useful tool for the professional audio industry and outperforming other professional programs...

Ross Chatwin, AuI ConverteR 48x44 since 2015

...I would recommend this software to anyone from a casual audio enthusiast seeking to upgrade the sound of their audio experience right through to the professional seeking industry standard seamless conversions...
