Audio File Convert


Audio file convert lossless formats WAV, FLAC, AIFF with AuI ConverteR 48x44


3 Issues of HD Audio Converters

1. Noise of shifted ultrasound

2. Restricted number of built-in output files formats

3. Mac launch with Windows emulation software


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

Restricted number of native output formats - downloadable high resolution audio files have FLAC, WAV, AIFF formats. Audiophile and professional conversion tools usually supply a restricted number of output formats. Wma, mp3, alac and other (used for hi-end mobile audio devices - portable and car systems) don't supported. Final audio conversion to destination format we make manually.

Mac launching with Win emulation software - many engineers and audiophiles use Mac. Some high resolution audio conversion tools has Windows version only.

Which can offers audiophile utilities for resolution ( sampling rate and bit depth) conversion of lossless files with intuitive interface?

Let me tell about decission these troubles. AuI ConverteR 48x44 is music converter designed specially for HD lossless files.

Why AuI ConverteR 48x44

1. Special design for high resolution audio conversion of lossless music

2. Removing noise of shifted ultrasound

3. Your customization of output files formats

Native launching for MS Windows and Mac OS X.


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

- conversion noise below noise of 24-bit quantisation;

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

- sampling 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 float internal audio processing.

Suppressing whistle and noise of shifted ultrasound with alphaC sample rate conversion algorithm.

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

What is FLAC File [Article]

FLAC (Free Lossless Audio Codec) is audio codec to lossless compression and file container for music stuff. This file have extension like the codec name.

"Lossless" mean "original and compressed audio content are fully identical binary".

Sound quality issues are reviewed below.

Where is the Limit of Audio Quality?

I read many endless discussions about audio equipment: cables, lossless vs. lossy, compression algorithms, jitter, ultrasound, playback files from different places of hard disk, power conditioners, etc.

I suppose, reason of the discussions is small perceived sound difference, that is not obvious for everybody, or no difference.

It is the end of high-end?

Below I want to discuss: can we get sound improvement, obvious for almost everyone, in future audio equipment?
