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.


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, SACD ISO) of 1-bit audio (a.k.a. DSD);
  • trueG - True Gapless Conversion - processing to eliminate artefact at borders of album tracks (ISO, DSF, DFF, FLAC, WAV and other) conversion (true gapless conversion, smoothDC);
  • safeR - Safe CD ripping - forced detection of CD reading errors with trying of restore damaged audio data.
