Every week bulk of downloadable HD digital audio are growing.
At home we amass a huge audio libraries.
We need converting audio formats and resolution for:
- compatibility with DAC and players,
- reducing disk space occupied music
What is best audiophile file format converter tools?
Main claim to the best audio converter for Mac is pure sound and minimum noises.
Hi-end ( professional ) converting utilities on the market has:
- low level of noise,
- built-in dithering,
- minimum phase filter.
Dithering - method of audio transparency enhancement for 16 bit resolution conversion.
Minimum phase filter (Analog mode) (of sample rate conversion) - sound burn noise for digital sample frequency conversion. First you listen the (pre-sound) noise. After very short time appear sound. Conversion utility in this mode efficiently restrict the pre-sound noise.
But hi-end music conversion tools have some problems :
Restricted number of native output file formats - high resolution downloadable audio files stores in FLAC, WAV, AIFF lossless formats. As rule audiophile and pro software for conversion support a restricted output formats number. Don't supported formats ogg, mp3, alac and other (used for hi-end mobile audio devices: car and portable systems). Need additional manual audio converting of file with changed bit-depth and sample rate to destination format.
User must be able add necessary format of output files. Third-parties encoders can be connected via command line with parameters.
Noise of shifted ultrasound: shortcoming of audio devices cause ultarsound become audible as noise. Especially it might appear during playback high resolution at high loudness level.
Best audio converter should fix the noise.
Starting on Mac OS X with Win emulation software - many producers and audiophiles use Mac. Some HD audio conversion tools has Windows version only.
Should be special app version for Mac OS X.
Сan not call any converter is the best. On audiophile market we have several alternatives always.
Note the AuI ConverteR 48x44 into the Audiophil-E version ($109,7).
This is an excellent price-quality ratio for the professional audio converter with rich features and excellent sound. Compare it to the price of alternatives - audiophile-grade converters for audio files.
- FLAC support
- Output format customizing
- Dithering and Analog mode
- Native Mac run
About AuI ConverteR 48x44
Special design for high resolution conversion of lossless files WAV, FLAC, AIFF:
- 64-bit float all internal sound processing;
- noise of conversion below noise of 24-bit quantisation;
- 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);
- sampling rate conversion without pre-ringing at output. Like to analog processing audio (minimum phase filter mode or Analog mode);
- sample rate converting without phase distortions. Fine for such sounds as drums, piano, guitar (linear phase filter mode).
Removing noise of shifted ultrasound simultaneously with sample rate conversion algorithm alphaC.
User customization of output files formats : after conversion automatically starting command line encoder app by third-parties developers. You can link your encoder utilities off one's own bat.
Some sets of modules can have lower price in one of editions considered in the table below.
