Since our CD player can play FLAC encoded files up to 96KS,
we use AuI ConverteR 48x44 software, so that we can provide right examples. ..."
With the variety of free and paid converters for hi-res lossless files, high qualitive ones is unitary.
I use AuI ConverteR 48x44 almost a year. In previous versions there were "bugs" that the program developer fix fairly quickly. What does the author's desire to constantly improve the software.
All statements on the official website and the features of the software corresponds to the actual results obtained.
Currently AuI ConverteR 48x44 is a priority program for converting of files. Especially for high-resolution audio.
From my own experience I recommend use the software for all music lovers and interested professionals."
AuI ConverteR 48x44
Test your gears for intermodulations
Intermodulations is different combinations of ultrasound frequencies - add, subtract, multiplying.
Download hi-resolution files with 2 ultrasound harmonics (30 and 33 kHz): 96 kHz and 192 kHz.
If you system has non-linearity you listen noise and/or whistle (30-33=3 kHz, 33*2-30*2=6 kHz, etc.).
WARNING: be very careful with your ears avoid harm for it. Before listening set amplifier sound volume to minimum. Increase level of volume little by little. When will feel discomfort in the ears immediately discontinue use.
Make conversion with output sample rate same as input.
Usable result: audio haven't noise, hi-resolution preserved for using DAC capabilities.
