Mac OS X Audio Converter

We view here choice of Mac OS X HD audio file converter.

What some troubles of high resolution audio converters? We have three troubles.

HD Audio Converters: 3 Troubles

1. Noise of shifted ultrasound

2. Restricted number of  built-in output formats

3. Mac starting with Win emulation software

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

Restricted number of built-in output formats - downloadable high resolution audio files have FLAC, WAV, AIFF formats. Audiophile conversion software usually support a limited number of output formats. Formats wma, mp3, alac and other (used for high resolution mobile audio devices - portable and car systems) don't supported. Final conversion to destination format maked manually.

Mac starting with Win emulation software - often sound engineers and audiophiles use Mac. Some high qualitative audio conversion software has Windows version only.

Where audiophile utilities for resolution (sampling rate and bit depth) converting of lossless audio  files with friendly interface?

Now about decission these troubles. AuI ConverteR 48x44  is Mac OS X audio converter specially designed for HD lossless files.


Why AuI ConverteR 48x44

1. Special design for HD audio conversion of lossless files

2. Suppressing noise of shifted ultrasound

3. User customization of output format

With native launching for Mac OS X.


Special design for high resolution conversion of lossless files WAV, FLAC, AIFF

    - conversion noise below 24-bit quantisation noise;

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

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

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

    - 64-bit floating point internal audio processing.

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

User customization of output format - after resolution conversion automatic launching of command line utilities by third-parties developers. You can connect your encoders off one's own bat.
