WAV Sample Rate


Every month volume of downloadable HD music are growing.

At our home we store a huge audio libraries.

We need converting audio formats and for:

- compatibility with DAC and players,

- curtailing hard disk space occupied music

- other.


What is file converter for lossless WAV sample rate?

Primary requirement to the software is pure sound and minimum noises (loses).


Hi-end ( professional ) converters on the market has:

- low level of distortions,

- built-in dithering,

- minimum phase filter.


Dithering - method of audio purity enhancement for 16 bit conversion.


Minimum phase filter (Analog mode) (of sample rate conversion) - sound cause noise for digital sampling rate conversion. Primarily you listen the (pre-sound) noise. After some milliseconds appear sound. Conversion utility in this mode efficiently fix the pre-sound noise.


However hi-end music conversion utilities have three troubles :

1. Limited range of built-in output file formats

2. Noise of shifted ultrasound

3. Starting on Mac OS X hardware via Win emulation software


Restricted number of built-in output formats - HD downloadable music files have format (FLAC, WAV, AIFF). As rule high resolution and professional tools for conversion supply a limited number of output formats. Don't supported formats ogg, mp3, alac and other (used for qualitative mobile audio gears: car and portable systems). Need additional manual conversion of file with changed resolution to final format.


User of AuI Converter 48x44 able add required output file format. Third-parties encoders (executive files) can be connected via command line with parameters.


Noise of shifted ultrasound: shortcoming of audio apparatus cause ultarsound become audible as noise. Especially it might rising during playback high resolution at high loudness power.


AuI Converter 48x44 suppress the noise.


Launching on Mac with Win emulation software - many producers and audiophiles use Mac. Some HD audio conversion tools has Windows version only.


AuI Converter 48x44 application has version for Mac.


Which can offers audiophile tools for resolution ( sample rate and bit depth) conversion of lossless files with intuitive interface?

About AuI ConverteR 48x44

Special design for high resolution converting of lossless files WAV, FLAC, AIFF:

- 64-bit floating point internal sound processing;

- noise of conversion below 24-bit quantisation noise;

- dithering for improving of transparency 16 bit converting (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit, 16 bit to 16 bit);

- sample frequency conversion without pre-ringing at output. Like to analog processing audio (minimum phase filter mode);

- sample frequency converting without phase distortions. Fine for such instruments as drums, piano, guitar (linear phase filter mode).

Suppressing noise of shifted ultrasound simultaneously with alphaC sampling frequency conversion algorithm.

User customization of output files formats : after audio resolution conversion automatically starting command line encoder app by third-parties developers. You can link your encoders off one's own bat.
