Professional high-end sample rate converter of lossless audio files for music production and audiophiles.


Advantages

1. Low distortions at conversion. The unique algorithm of sampling rates conversion (result of numerous researches and experiments), used in AuI ConverteR 48x44, has allowed to reduce level of conversion noise (artefacts) to minus 140 dB.

For comparison:

minus 96 dB - theoretical limit of noises for 16-bit samples of compact disk;

minus 120 dB and above - noises of analog-digital converters of 24-bit professional sound cards.

2. Automatic Signal Level Scaling for reduction of bit-per-sample count (as example, input=24 to output=16 bit-per-sample).

3. Double precision (64-bit floating point) algorithms used for processing.

4. Handling multichannel files.


Specification

1. Format of input files

1.1. Sampling rates (kHz) - 44.1,48,88.2,96,176.4,192.

1.2. Processing of multichannel audiofiles - yes.

1.3. Bit-depth - integer: 16 and 24; (WAV only) floating point: 32 and 64.

1.4. FLAC, uncompressed AIFF, WAV support.

2. Format of output files

2.1. Sampling rates (kHz) - 44.1,48,88.2,96,176.4,192.

2.2. The amount of channels - as input file.

2.3. Bit-depth - integer: 16 and 24; (WAV only) floating point: 32 and 64.

2.4. Bit-depth select by user.

2.5. FLAC, uncompressed AIFF, WAV support.

3. Level of conversion noise, better than: -140 dB.


Level noise of output file depends on bit-per-sample of input and output files.

Level of conversion noise better than -140 dB is reached at bit-per-sample not less than 24 bits, or 32/64 bit floating point.

4. Dither - supported.

5. Using Multi-CPU/cores for batch processing - supported.


Limitation of FREE version:

1. Not supported batch processing group of files.

2. ConverteR 48X44 FREE is closed after conversion of one file.

3. Started only one instance simultaneously.
