Every year volume of downloadable audiophile audio are growing.
At our home we amass a vast audio libraries.
We need converting music formats and resolution for:
- compatibility with DAC and players,
- curtailing hard disk or disk storage space occupied music
How to convert audio files with minimum quality loss?
First claim to file format converter software are clear sound and minimum distortions.
Audiophile ( pro ) converting tools on the market has:
- low level of distortions,
- embedded dithering,
- minimum phase filter.
Dithering - method of audio purity improvement for 16 bit resolution converting.
Minimum phase filter (Analog mode) (of sample rate conversion) - sound cause noise for digital sample frequency conversion. Primarily you listen the (pre-sound) noise. After some milliseconds you hear sound. Conversion tool in this mode efficiently fix the pre-sound noise.
But high qualitative audio converters have some troubles :
Restricted number of built-in output formats - HD downloadable audio files have format (FLAC, WAV, AIFF). As rule high resolution and professional utilities for conversion support a limited range of output formats. Don't supported formats wma, mp3, alac and other (used for qualitative mobile audio gears: car and portable systems). Required additional manual conversion of file with changed bit resolution and sample rate to final format.
User of AuI Converter 48x44 able add necessary output file format. Third-parties encoders can be connected via command line.
Noise of shifted ultrasound: imperfection of audio apparatus cause ultarsound become audible as noise. Especially it might appear during playback high resolution at high loudness power.
AuI Converter 48x44 suppress the noise.
Runing on Mac with Windows emulation software - many engineers and audiophiles use Mac. Some high resolution audio conversion converters has Windows version only.
AuI Converter 48x44 software has Mac OS X version.
Which can offers HD audio tools for resolution ( sample rate and bit depth) converting of lossless files with user friendly interface?

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