Today we talk about choice of high qualitative audio converter for Mac OS X.
We have some problems of high resolution audio conversion? Known at least 3 problems.
Noise of shifted ultrasound - noise (or intermodulation distortions) occurs due non-linear distortions of analog part of audio devices during playback high resolution (88/96/176/192 kHz) files.
Restricted number of output formats - downloadable music usually in FLAC, WAV, AIFF formats. Pro audio converters usually support only a limited number of built-in output formats. Sometime wma, mp3, alac, other (used in qualitative mobile audio) don't supported. We need final manual converting to destination format.
Mac start with Windows-emulator software - many professionals and audiophiles using Mac. Some high quality audio converters available price are Windows compatible only.
We need audiophile tool for change audio resolution (sample rate and bit depth) of lossless files with frienly interface.
Let me talk about decission these troubles. New audiophile software AuI ConverteR 48x44 is audio converter for Mac OS X special designed for high resolution lossless files.
And native launching for Mac OS X.
Special design for audio resolution conversion of lossless files WAV, FLAC, AIFF
- noise of conversion below noise of 24-bit quantisation;
- sampling rate conversion mode without phase distortions (linear phase filter). It's fine for sounds with sharp attack (drums, piano, guitar);
- sample rate conversion mode without pre-ringing (minimum phase filter). It like to analog filtration;
- Audiophile Inventory's alphaD dithering for improving of transparency of 16 bit conversion (16 -> 24/32, 24/32 -> 16);
- 64-bit floating point internal audio processing.
Suppressing noise of shifted ultrasound into Audiophile Inventory's alphaC algorithm of sample rate conversion.
User customization of output format - automatic (after resolution conversion) launching of command line encoder utilities. User can on one's own connect necessary utilities.
Some sets of modules can have lower price in one of editions considered in the table below.
