The Modern View of HD Converting Audio Files

Buying downloadable music at online stores and digital home libraries became usual for audiophiles.

Now we have a huge number of digital audio formats and audio devices.

Demands of a wide range of listeners to the quality of sound are steadily increasing.

We want listen qualitative downloaded music at our cars and mobile phones expecting pure sound. A lot of car audio systems support only CD as lossless source.

But audio resolution conversion (sample rate and bit depth) has loss of quality always.

Whether comply existing audio converters with modern realities?

Applications of Audio File Resolution Conversion

 

3 Troubles of HD Audio Converters

1. Noise of shifted ultrasound

2. Restricted number of output formats

3. Mac launch with Win-emulator software.

    Noise of shifted ultrasound: this noise (intermodulation distortions) occurs due non-linear distortions of analog part of audio devices during playback 88/96/176/192 kHz files.

Intermodulation distortions

 

     Restricted number of output formats: Downloadable files usually have FLAC, WAV, AIFF formats. HD audio converters often support only a limited number of built-in output formats. Often wma, mp3, alac, other (used in qualitative mobile audio) don't supported. Need manual final converting to the desired format.

     Mac launch with Win-emulator software: many professionals and audiophiles using Mac. Some HD-quality audio converters are written only for Windows.

 

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 and for Windows.

 

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

    - noise of conversion below noise of 24-bit quantisation;

    - sample rate conversion mode without phase distortions (linear phase filter) fine for sounds with sharp attack (drums, piano, guitar);

    - sample rate conversion mode without pre-ringing (minimum phase filter) like analog filtration;

Linear Phase Filter vs. Minimum Phase Filter

    - original alphaD dithering for improving of transparency of 16 bit conversion;

    - 64-bit floating point all internal processing.

Suppressing noise of shifted ultrasound embodied into alphaC algorithm of sampling rate conversion.

User customization of output format is automatic (after resolution conversion) launching of command line encoder utilities. User can on one's own connect necessary utilities.
