Here we view how choose HD audio file converter (free audio converter downloads - for Windows and Mac - placed below).
What issues of high qualitative audio converters? We have three troubles.
Noise of shifted ultrasound is noise (intermodulation distortions) appear due non-linear distortions of analog part of audio equipment for playback of HD (88/96/176/192 kHz) files.
Restricted range of built-in output formats - downloadable HD audio files have FLAC, WAV, AIFF formats. Audiophile and professional conversion software usually support a restricted number of output formats. Wma, mp3, alac and other (used for hi-end mobile audio gears - portable and car systems) don't supported. Final audio conversion to destination format we make manually.
Mac OS X starting with Windows emulation software - often sound producers and audiophiles use Mac. Some high resolution audio conversion utilities has Windows version only.
Which can offers HD audio software for resolution ( sampling rate and bit depth) conversion of lossless files with user friendly interface?
Now about solutions these problems. AuI ConverteR 48x44 is audio conversion software specially designed for HD lossless files.
User interface of AuI ConverteR 48x44
With native starting for Mac OS X and Windows.
Special design for HD converting of lossless files WAV, FLAC, AIFF:
- noise of conversion below 24-bit quantisation noise;
- sampling rate conversion without phase distortions. Fine for such sounds as drums, piano, guitar (linear phase filter mode);
- sample rate conversion without pre-ringing at output. Like to analog sound processing (minimum phase filter mode);
- alphaD dithering algorithm for improving of transparency for 16 bit conversion (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit);
- 64-bit floating all internal audio processing.
Fixing noise of shifted ultrasound with alphaC sample rate conversion algorithm.
User customization of formats of output files - after audio resolution converting automatically launching of command line encoder utilities by third-parties developers. You can connect your encoder utilities off one's own bat.
