AuI ConverteR 48x44
is HD audio converter for audiophile quality. Supported native processing of high resolution lossless files WAV, FLAC, AIFF.
You can customize output formats (wma, alac, mp3 etc.) via simple connecting command line external encoders (using graphical user interface).
Intended for professional music production, DJ, audiophiles.
Supported platforms: Mac OS X and Windows.
Every year volume of downloadable audiophile quality digital audio (24bit 96khz music FLAC, WAV, AIFF and better) are growing.
At home we accumulates a vast audio high fidelity libraries.
We need converting music formats and for:
- compatibility with DAC and players
- cuting down disk or disk storage space occupied audio files
What is high resolution audiophile quality converter audio files?
Primary claim to the software is transparent sound and minimum noises.
Audiophile quality ( professional ) converting utilities on the market has:
- low level of distortions,
- in-built dithering,
- minimum phase filter.
Dithering - method of sound clarity improvement for 16 bit conversion.
Minimum phase filter (Analog mode) (of sample rate conversion) - sound cause noise for digital sampling rate conversion. First you listen the (pre-sound) noise. After very short time appear sound. Converter in this mode efficiently restrict the pre-sound noise.
But high resolution high audio quality tools have some troubles :
Restricted number of built-in output formats - audiophile quality music files have lossless (FLAC, WAV, AIFF). As rule HD and pro tools for conversion support a limited output formats number. Don't supported other formats (wma, mp3, alac etc. ) (used for HD mobile audio gears: car and portable systems). Required additional manual audio conversion of file with changed bit-depth and sampling frequency to terminal format.
User of AuI Converter 48x44 able append necessary format of output files. Third-parties encoders (executive files) can be connected via command line.
Noise of shifted ultrasound: imperfection of audio apparatus cause ultarsound shifted to bottom and become audible as noise. Especially it might rising during playback high resolution at high loudness power.
AuI Converter 48x44 suppress the noise.
Starting on Mac OS X with Windows emulation software - many engineers and audiophiles use Mac. Some high sound quality conversion converters has Windows version only.
AuI Converter 48x44 software has version for Mac OS X.
Which can offers HD audio utilities for resolution (sampling rate and bit depth) conversion of lossless files with intuitive interface?

About AuI ConverteR 48x44
Special design for audio high fidelity conversion of lossless WAV, FLAC, AIFF files:
- 64-bit float internal sound processing;
- conversion noise below noise of 24-bit quantisation;
- dithering algorithm for improving of purity 16 bit conversion (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit, 16 bit to 16 bit);
- sampling frequency converting without pre-ringing at output. Like to analog audio processing (minimum phase filter mode);
- sample frequency converting without phase distortions. Fine for such instruments as drums, piano, guitar (linear phase filter mode).
Fixing noise of shifted ultrasound simultaneously with sample frequency conversion algorithm alphaC.
User customization of formats of output files : after converting automatically launching encoder utilities via command line by third-parties developers. You can link your encoder utilities off one's own bat.
