Popular Post FredericV Posted April 15, 2021 Popular Post Share Posted April 15, 2021 MQA's leaky filter effects can also be done with sox (see link in my signature) Regular minimum phase with long post ringing vs one cycle of postringing + aliasing. During my truncation experiments I already noticed 16 bit MQA files (which lack the hi-res part for the first octave above redbook) have similar aliasing as the sox recipe: What the independent MQA researchers already knew, is being confirmed once again thanks to your post. botrytis and GoldenOne 1 1 Designer of the 432 EVO music server and Linux specialist Discoverer of the independent open source sox based mqa playback method with optional one cycle postringing.

Popular Post FredericV Posted April 21, 2021 Popular Post Share Posted April 21, 2021 Just found this example in their secret group: "I compare many tracks from Qobuz hi-res and tidal mqa and does unfold to the same sample rate as these fake hi-res file they sell these day. " Fore sure MQA adds something which is not in the 24/192 version on Qobuz. Does he actually believe Qobuz is the fake version, and MQA is the real version, while it shows the aliasing from the leaky upsampler in the MQA version which was not in the Qobuz version? bambadoo and Currawong 2 Designer of the 432 EVO music server and Linux specialist Discoverer of the independent open source sox based mqa playback method with optional one cycle postringing.
