![]() In the lower picture part, we can observe the mirrored image of the input sweep tone. At the top part of the picture, we can view only input sine without excessive products (aliases).ĭSD to PCM conversion is based on downsampling. Because, as rule, the input sampling rate is higher than output one (in instance, 2.8 MHz and 96 kHz, respectively).ĭownsampling requires low-frequency filtering. Otherwise, the high part of the input spectrum folds into the audible range of the output signal. Viewed aliases in the picture demonstrate it. Higher conversion accuracy requires more computing time. In some cases, playback-noise level can be achieved via reducing of the output frequency band. In AuI ConverteR Settings > General tab > see Filter mode list. Playback noise for high-resolution sound files may be solved via "Optimized" filter mode.
