High resolution audio converter AuI ConverteR 48x44 PROduce-RD (Windows / Mac OS X) support conversion 32 bit FLAC to/from FLAC (up to 32 bit), WAV, AIFF, DSF, ALAC, mp3,... with sample rates 44.1 kHz / 48 / 88.2 kHz / 96 kHz / 176.4 kHz / 192 kHz / 352.8 kHz / 384 kHz.
Supported multichannel files and export meta tags for converted files.
Priority line the converter is sound quality - keeping (as possibly) converted signal unchanged.
When digital signal converted to analog into Digital Analog Converter (DAC) usually audio data from music file oversampled to high sample rate for digital filtration before analog filtration.
Analog filtration restore analog signal from digital signal. Analog filter connect "stairs" of digital samples via uninterrupted line.
But for analog filter very hardly achieve deep filtration of aliases (distortions) during digital-analog conversion. Therefore before analog filtration used deep digital inline ("on fly") filtration.
AuI ConverteR 48x44 makes deep filtering of aliases during offline (non-realtime) oversampling with "heaviest" digital signal processing. Other words it allow done half of DAC's work with very accurate offline algorithms.
