Recently I’ve had one of those marker experiences, you know, when your whole audio history flashes before your eyes. You remember your first Sony Walkman and the euphoria of discovering real audiophile gear to the present digital wonders. For me OOYH has been a big part of that “journey” scaling with all my refinements of taste and component upgrades. Each time OOYH enhanced those changes and in turn benefited, but something happened which just caused OOYH to take a dramatic leap forward.
I’ve been experimenting with DSD512 resampling lately and have been marvelously impressed with the results in general, However, it affected OOYH in a way that just truly startled me. I started with real time conversion in Audirvana Plus, HQ player, Roon, etc. The problem is that you can’t feed this into OOYH because OOYH needs a 48Khz sample rate. So, I went to off line conversion, resampling after OOYH instead of before. I captured the direct output from the OOYH mixer using a virtual output (IShowU) and tracked this in Logic to a 24bit 48Khz wav (caf). I sliced up the results with Audacity and then upconverted to DSD512 using Xivero XiSRC or AuI Converter.
What was a limitation of OOYH’s sample rate capability became a surprising benefit. What this process does is that it not only resamples the source audio at an exponentially higher rate, it resamples the effects of OOYH’s convolution. This, of course, isn’t the place to get into the raging debate over the merits of DSD. I can only tell you what I hear in my system, which is itself pretty pristine.
I’ve always loved OOYH, but of course it has its deficiencies. I alway thought that, even if you find a good preset fit, which I have, there is still a hazy, diffuse quality to the sound. This is especially apparent in the vocals which are upfront and center and need to coalesce to be convincing. This was always an issue I overlooked because of everything else that OOYH brough to the table. I can only guess at the science, but subjectively, DSD resampling has resolved this for me. The resulting transparency, clarity, and coherency has caused OOYH to cross a threshold where it really approximates a boutique speaker system. As an added benefit you can take these files mobile on a DAP. For me that was always actually the goal.
Resampling to DSD512 also has its downsides. For one you need to have a DAC that can handle native or DoP DSD512. Also, it takes enormous processing power over a long time and produces huge files (1 track = 1 - 3Gb). In the end, the success of this process will no doubt be heavily system dependent. It may be worth exploring though if you have a DSD512 capable DAC, especially because the cost of entry is low. Xivero XiSRC converter is less than $20 and Audacity and IShowU are free. For myself, after a long long road, the out of your head effect is finally complete and I just wanted to share.
