The audio converter F.A.Q.

You may do different benchmarks: listening and measurements.

In commercial version you will get absolutelly same quality that in FREE demo version.

Below see links to conversion software comparisons.


3. Why AuI ConverteR too expensive?

It only seems at first look.

AuI ConverteR is designed as pro-audio tool for studios. So need compare the conversion software's price with world the best professional decissions.

You can be assured, that you have studio quality available at home computer at resonable cost.

Indeed, maximal edition PROduce-RD's price look too high for audio converter software. But you can compare it by price and available functionality with other studio tools.

AuI ConverteR intended not only for studios, but it have rich functionality that need for home applications: converting music formats for hi-fi and portable music devices, changing resolution audio, metadata management, safe ripping of audiophile CD collection.

Or ask us to configure for you >

Configuration PROduce-RD have lower price, than Modula-R's module kit that have all functionality.


5. Why I see at spectrum cut at 20 kHz?

This audio converter have several conversion modes (band output signal):

- optimized (cut ultrasound upper 20 kHz);

- non-optimized (cut ultrasound DSF upper 20 ... 24 kHz, PCM up to 384 kHz - depend on sample rate);

- wide non-optimized (cut ultrasound DSF upper 20 ... 100 kHz, PCM up to 384 kHz - depend on sample rate).

Some apparatus cause non linear distortions that generate audible products (distortions) by inaudible ultrasound. Band limitation allow to reduce the distortions of the apparatus.

You can choose preferable mode in Settings window (push Settings button in main window) > General tab > Filter mode list.

General recommendation (and default settings) is optimized mode. But you can choose resampling filter mode that you like more.


6. What signal processings you use?

In our audio converter we use only own Audiophile Inventory's algorithms:

  • alphaC - resampling algorithm with individual manually adjusted filter for each of combinations input/output sample rates;
  • alphaD - gentle dithering algorithm, its aim is minimization of impact to musical signal;
  • alphaS - low distortion/noise sigma delta modulator (DSF)/demodulator (DSF, DFF, ISO) 1-bit audio;
  • Clickless processings - processing to eliminate clicks of album tracks (ISO, DSF, DFF, FLAC, WAV and other) conversion (true gapless conversion, smoothDC);
  • Safe CD ripping - forced detection of CD reading errors with trying of restore damaged audio data.
