4 Issues of HD Audio Converters

  1. Level of noise and distortions into converted stuff
  2. Noise of ultrasound intermodulations.
  3. Supported channel number.
  4. Native launch under Mac OS and Windows.


Level of noise and distortions into converted stuff - AuI ConverteR is professional software and provide level of noise and distortions that demands studio applications.

Noise of ultrasound intermodulations is audible noise/distortions, that appear due non-linear distortions of analog part of audio devices in playback of HD (88/96/176/192 kHz and higher) files. AuI ConverteR have optimized conversion mode that cut ultrasound to avoid of audible intermodulations noise. As alternative you can set wide band non-optimized modes.

Supported channel number - AuI ConverteR support stereo and multichannel files.

Native launch under Mac OS and Windows - many engineers and audiophiles use Mac. AuI ConverteR launched on Mac and Windows without additional emulation tools.


AuI ConverteR 48x44 is HD audio converter software specially designed for high resolution lossless files.


HD audio converter AuI ConverteR 48x44



Special design for HD conversion of lossless files WAV, FLAC, AIFF and 1-bit audio files DSF, DFF, ISO*:

- conversion noise below 24-bit quantization noise;

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

- sample rate converting without pre-ringing at output. Like to analog sound processing (minimum phase filter mode);

- alphaD dithering algorithm for improving of transparency for 16 bit conversion (16 bit to 24 bit/32 bit/64 bit, 24 bit/32 bit/64 bit to 16 bit);

- 64-bit floating point internal audio processing.


* - DFF and ISO [1-bit audio] is input formats only.



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

User customization of output files formats - after resolution converting automatically launching of command line encoder utilities by third-parties developers.
