Audio Quality Converter

AuI ConverteR 48x44 is software audio quality converter for AIFF, FLAC, WAV.

3 Troubles of HD Audio Converters

1. Noise of shifted ultrasound

2. Restricted number of native output formats

3. Mac starting with Windows emulation software

Noise of shifted ultrasound is noise (intermodulation distortions) appearing due non-linear distortions of analog part of audio equipment for playback of HD (88/96/176/192 kHz) files.

Restricted range of built-in output formats - downloadable HD audio files often have FLAC, WAV, AIFF formats. Audiophile and professional conversion tools usually support a restricted number of output formats. Wma, mp3, alac and other (used for HD mobile audio devices - portable and car systems) don't supported. Final converting to destination format maked manually.

Mac launching with Windows emulation software - many producers and audiophiles use Mac. Some high qualitative audio conversion utilities has Windows version only.

Now about solutions these troubles. AuI ConverteR 48x44 is music converter specially designed for high resolution lossless files.

AuI ConverteR 48x44's Benefits

1. Special design for HD audiophile conversion of lossless files

2. Removing noise of shifted ultrasound

3. User customization of output files formats

Native launching for MS Windows and Mac OS X.

Special design for HD converting of lossless WAV, FLAC, AIFF files:

- conversion noise below 24-bit quantisation noise;

- sample rate conversion without phase distortions. Fine for such instruments as drums, piano, guitar (linear phase filter mode);

- sample rate conversion without pre-ringing at output. Like to analog audio processing (minimum phase filter mode);

- alphaD dithering for improving of transparency for 16 bit conversion (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit);

- 64-bit floating point internal audio processing.

Fixing noise of shifted ultrasound with alphaC sample rate conversion algorithm.

User customization of formats of output files - after audio resolution conversion automatically starting of command line encoders by third-parties developers. You can connect your encoder utilities off one's own bat.

...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...

"We do develop and built high end HiFi devices like integrated amplifier, power amplifier, phono preamplifier, pre amplfier, cd-player and audio streamer. We attach particular importance to maximum spatial resolution, but avoid the typical harshness sound in semiconductor amplifiers and digital equipment. ...

Since our CD player can play FLAC encoded files up to 96KS, we use AuI ConverteR 48x44 software, so that we can provide right examples. ..."

"...After many attempts to get my music data in the correct format, I discovered the positive characteristics of the dither function of AuI. I converted different music samples with dither. Burned the data with and without dither on CD and show this also to my colleagues in my branch. There was not one among them who could say something different as I'm. The original and the with the dither function converted samples sounded different.

The dither generated music data that sounded more fine then the original. The attacks in side instruments had more dynamic. The space was more clear. A decaying sound was to be heard longer, right down to the quietest passages. The whole sound had gained. But frequency analyzes indicated no difference, although you can hear differences. ..."

...Finally, I have chosen AuI ConverteR, simply because I find the sound quality of the files converted by it is better than the other softwares that I have tried...

"When I searched on the web to find software for converting my collections of DSF files to WAV or FLAC files to fit for my equipment setup, I found AUI ConverteR and some other softwares.

Before deciding to go for which one, I had compared the sound quality of the WAV files converted by these softwares. Finally, I have chosen AuI ConverteR, simply because I find the sound quality of the files converted by it is better than the other softwares that I have tried. In addition, it is also a nice experience to feedback my suggestions to the AUI developer for improvement and fixing issues. He always responds friendly and quickly.

I hope to continue to use it happily for my various conversion projects."

...AuI was one of the few converters that had the options I wanted, especially 32 bit...

"I have spent a lot of money building a stereo system including a water-cooled media server. I have several thousand CDs that I am ripping. There is a big difference in sound quality between lossless uncompressed files (WAV) and lossless compressed files (WMA). I started with WMA due to the difference in file size compared to WAV. In the past, data storage was not inexpensive and 2 TB discs were the maximukm size you could buy. Now storage is getting cheaper and 4TB hard drives are becoming common. Now I am looking into converting the files to WAV.

It is becoming apparent that 32 bit is the way of the future, so no sense in buying software that does not handle 32 bit (same with a DAC). The AuI was one of the few converters that had the options I wanted, especially 32 bit.

About communication with Audiophile Inventory's team: Excellent and immediate responses."

...So I find myself using Aul ConverteR all the time for multiple audio needs...

"Infact I stumbled across your software while looking for a DSF to PCM converter for Windows before the RD version ever came out. I could only find Open Source Linux and Mac Software, one without a GUI and another with a very suspect one.
Best part about it is, IMO it is a superior sample rate and format converter than using my wave editor... So I find myself using Aul ConverteR all the time for multiple audio needs.

...In previous versions there were "bugs" that the program developer fix fairly quickly...

"I'm experienced music lover. Thus I prefer possible most qualitative of available formats.
   With the variety of free and paid converters for hi-res lossless files, high qualitive ones is unitary.

    I use AuI ConverteR 48x44 almost a year. In previous versions there were "bugs" that the program developer fix fairly quickly. What does the author's desire to constantly improve the software.
    All statements on the official website and the features of the software corresponds to the actual results obtained.

    Currently AuI ConverteR 48x44 is a priority program for converting of files. Especially for high-resolution audio.

    From my own experience I recommend use the software for all music lovers and interested professionals."
