audiventory Posted February 10, 2017 Share Posted February 10, 2017 I meant to say the opposite; I.e., it appears to me it is just upsamped CD. Note the very sharp drop-off at 22kHz. I suppose, that software upsampled CD must have lower level (even for "not-the-best" resampler) of noise and must not have tone about 30 kHz. Looks like, it is playback a source (CD?) and recapturing analog signal in new resolution. Though -75 dB is too big level noise for modern ADC and DAC. asdf1000 1 AuI ConverteR 48x44 - HD audio converter/optimizer for DAC of high resolution files ISO, DSF, DFF (1-bit/D64/128/256/512/1024), wav, flac, aiff, alac, safe CD ripper to PCM/DSF, Seamless Album Conversion, AIFF, WAV, FLAC, DSF metadata editor, Mac & WindowsOffline conversion save energy and nature Link to comment
