Mac Audio File Converter

We talk here about choice of Mac audio file converter for HD lossless.

What some troubles of high resolution audio converters? We have 3 troubles.

3 Problems of HD Audio Converters

1. Noise of shifted ultrasound

2. Restricted number of  built-in output formats

3. Mac launch with Windows emulator software

Noise of shifted ultrasound - noise (intermodulation distortions) rise due non-linear distortions of analog way of audio devices for playback HD (88/96/176/192 kHz) files.

Restricted number of output built-in formats - downloadable high resolution audio files have FLAC, WAV, AIFF formats. Pro audio converter software usually support a limited range of output formats. Such formats as wma, mp3, alac and other (used for HD mobile audio) don't supported. Final converting to destination format maked manually.

Mac launch with Windows emulation software - often sound producers and audiophiles use Mac OS X. Some high resolution audio conversion software have Windows version only.

Where audiophile tool for audio resolution (sampling rate and bit depth) conversion of lossless files with user friendly interface?

Now we have decission these problems. New AuI ConverteR 48x44  is Mac audio file converter specially designed for HD lossless.

Why AuI ConverteR 48x44

1. Special design for audio resolution conversion of lossless files

2. Suppressing noise of shifted ultrasound

3. User customization of output format

And native launching for Mac OS X.


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

    - conversion noise below 24-bit quantisation noise;

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

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

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

    - 64-bit floating point full audio processing.

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

User customization of output format - after resolution conversion automatic launch command line encoder software by third-parties developers. You can connect new encoders off one's own bat.
