Every week volume of downloadable hi-res digital music are growing.
We need batch converting of huge music libraries for:
- compatibility file resolution with DAC and players,
- cuting down hard disk space occupied audio files
First requirement to this software is pure sound with minimum noises and maximal using of multi-CPU computer power.
As rule, high resolution audio conversion software on market have 3 problems :
Limited number of native output formats - high resolution downloadable music files have lossless (FLAC, WAV, AIFF). HD and pro utilities for converting supply a limited number of output formats. Don't supported formats ogg, mp3, alac and other (used for mobile audio devices: car and portable systems). Required additional manual audio converting of file with changed bit resolution and sample rate to final format.
User of audio converter software must able add necessary output file format. Third-parties encoders (executive files) possible connected via command line.
Noise of shifted ultrasound: shortcoming of audio equipment cause ultarsound shifted to bottom and become audible as noise. Especially it might rising during playback high resolution at high loudness level.
Runing on Mac OS X with Win emulation software - many producers and audiophiles use Mac. Some HD audio conversion utilities has Windows version only.
Converter software must have Mac version.
Note the AuI ConverteR 48x44 Audiophil-E version ($109,7).
This is an excellent price-quality ratio for the pro audio converter software with rich features and perfect sound. Compare it to the price of alternatives - audiophile-grade converters for audio files.
- batch converting with simultaneous multi-CPU processing of several files
- FLAC support
- Output format customizing
- Dithering and Analog mode (see below)
- Native Mac run
About AuI ConverteR 48x44
Special design for high resolution converting of lossless WAV, FLAC, AIFF files:
- 64-bit floating point internal audio processing;
- noise of conversion below noise of 24-bit quantisation;
- dithering algorithm 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);
- sampling rate converting without pre-ringing at output. Like to analog processing audio (minimum phase filter mode);
- sample frequency conversion without phase distortions. Fine for such sounds as drums, piano, guitar (linear phase filter mode).
Removing noise of shifted ultrasound simultaneously with alphaC sampling frequency conversion algorithm.
User customization of formats of output files : after audio resolution conversion automatically launching command line encoder utilities by third-parties developers. You can link your encoder utilities off one's own bat.
