Every month volume of downloadable high resolution music are growing.
At our home we store a vast media libraries.
We need converting music formats and for:
- compatibility with DAC and players,
- retrenching hard disk or disk storage space occupied audio files
Primary requirement to best audio file converter tool is transparent sound with minimum distortions.
- low level of distortions,
- embedded dithering,
- minimum phase filter.
Dithering - method of sound purity improvement for 16 bit converting.
Minimum phase filter (Analog mode) (of sampling rate conversion) - sound cause noise for digital sampling rate conversion. Primarily you listen the (pre-sound) noise. After very short delay you hear sound. Converter in analog mode efficiently confine the pre-sound noise.
However high resolution audio converters have three issues :
Limited range of built-in output formats - HD downloadable music files have lossless (FLAC, WAV, AIFF). Usually HD and professional tools for converting supply a limited range of output formats. Don't supported other formats ( ogg, mp3, alac etc. ) (used for qualitative mobile audio gears: car and portable systems). Required additional manual conversion of file with changed resolution to final format.
Noise of shifted ultrasound: imperfection of audio equipment cause ultarsound shifted to bottom and become audible as noise. Especially it might rising during playback HD (88/96/176/192 kHz) at high loudness power.
Launching on Mac with Windows emulation software - often sound engineers and audiophiles use Mac. Some high qualitative audio conversion converters has Windows version only.
