Every month bulk of downloadable HD digital audio are growing.
At home we store a vast audio libraries.
We need converting music formats and resolution for:
- compatibility with DAC and players,
- reducing disk space occupied audio files
What is the best audio converter for Windows for audiophiles?
Main demand to this converters is pure sound with minimum noises.
High resolution ( professional ) conversion tools on the market has:
- low level of noise,
- built-in dithering,
- minimum phase filter.
Dithering - method of sound purity improvement for 16 bit conversion.
Minimum phase filter (Analog mode) (of sample rate conversion) - sound burn noise for digital sample 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.
But high qualitative audio conversion tools have 2 troubles :
Restricted number of native output file formats - HD downloadable music files stores in FLAC, WAV, AIFF formats. Usually audiophile and pro tools for converting support a limited number of output formats. Don't supported other formats (wma, mp3, alac etc. ) (used for qualitative mobile audio gears: car and portable systems). Need additional manual audio conversion of file with changed resolution to destination format.
Noise of shifted ultrasound: imperfection of audio apparatus cause ultarsound shifted to bottom and become audible as noise. Especially it might rising during playback HD at high loudness power.
Сan not call any converter is the best. On audiophile market we have several alternatives always.
Note the AuI ConverteR 48x44 into the Audiophil-E version ($109,7).
This is an excellent price-quality ratio for the pro audio converter software with rich features and perfect sound. Compare it to the price of alternatives - audiophile-grade converters for audio files.
- FLAC support
- Output format customizing
- Dithering and Analog mode (see below)
Special design for high resolution conversion of lossless files WAV, FLAC, AIFF:
- 64-bit floating point internal audio processing;
- noise of conversion below 24-bit quantisation noise;
- dithering for improving of transparency 16 bit converting (16 bit to 24 bit/32 bit, 24 bit/32 bit to 16 bit, 16 bit to 16 bit);
- sampling frequency conversion without pre-ringing at output. Similar to analog processing audio (minimum phase filter mode);
- sampling frequency converting without phase distortions. Fine for such sounds as drums, piano, guitar (linear phase filter mode).
Suppressing noise of shifted ultrasound simultaneously with sampling rate conversion algorithm alphaC.
User customization of formats of output files : after audio resolution conversion automatically launching encoders via command line by third-parties developers. You can link your encoder utilities off one's own bat.
