We view here how choose HD audio bitrate converter (sampling rate and bit resolution) for lossless files WAV, AIFF, FLAC.
What troubles of HD audio converters? We have 3 troubles.
Noise of shifted ultrasound is noise appearing due non-linear distortions of analog part of audio devices for playback of high resolution (88/96/176/192 kHz) files.
Limited number of native output formats - downloadable HD audio files have FLAC, WAV, AIFF formats. HD and professional conversion software usually support a limited number of output formats. Wma, mp3, alac and other (used for high resolution mobile audio devices - portable and car systems) don't supported. Final audio converting to destination format we make manually.
Mac OS X starting with Win emulation software - often sound engineers and audiophiles use Mac. Some high resolution audio conversion converters has Windows version only.
Which can offers audiophile tools for resolution ( sample rate and bit depth) conversion of lossless files with intuitive interface?
Let me tell about decission these problems. AuI ConverteR 48x44 is music conversion software designed specially for HD lossless files.
User interface of AuI ConverteR 48x44
Native launching for MS Windows and Mac OS X.
Special design for HD conversion of lossless files WAV, FLAC, AIFF:
- conversion noise below 24-bit quantisation noise;
- sample rate conversion without phase distortions. Fine for such sounds as drums, piano, guitar (linear phase filter mode);
- sampling rate converting without pre-ringing at output. Like to analog sound processing (minimum phase filter mode);
- alphaD dithering for improving of transparency for 16 bit converting (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit);
- 64-bit floating point all internal audio processing.
Removing whistle and noise of shifted ultrasound with alphaC sample rate conversion algorithm.
User customization of formats of output files - after resolution converting automatically launching of command line encoders by third-parties developers. You can link your encoders off one's own bat.
