"Pure Music" software discussion thread

[Onvinyl]

I've mailed with (one of) the maker(s), and they clarify this in the manual for people like me... 🙄

Meanwhile, I can really recommend using sox for riaa playback along with a decent prepre and a reasonable adc/dac. Using sox with command line linux keeps the diy spirit as well.

I'd like to push things a little further and try to implement different playback filters (CCIR and others) in sox's biquad command. So far, without sox-ess, haha. 🙄

I've found A biquad calculator | EarLevel Engineering but could not find reasonable values.

Should something like a program or spreadsheet exist that can spill out filter values for that purpose, I'd appreciate a hint or link.

I read about Pure Music in The Absolute Sound forums and downloaded the demo.
In my initial listening tests, I found PM (compared to iTunes) to be anemic ...

I remembered) that I had used the iTunes equalizer "Acoustic" preset on all of my stored music along with a gain adjustment set to 70% ...

I did the best I could to reproduce the quality of my iTunes preset, but never quite got it there.
As I mentioned to the PM tech, I thought that Pure Music was supposed to be a sizable improvement in sonics over iTunes and not an attempt to match it (which is what he and I were trying to do together) ...

I'm not a sound engineer and I don't have the time to study up on all of these aspects of playback in order to take the Pure Music playback beyond what iTunes is doing for me now.

To the best of my knowledge, Pure Music does not have, as one of its design objectives, the goal of "improving" any iTunes EQ presets, so a comparison based on how close one can come to doing so really says little or nothing about the value of the software. Most people who have suggested that the software is an improvement on iTunes have been talking about straightforward unequalized playback, ie, "pure" music rather than "changed for a particular purpose" music.
