That is if it is part of an end-to-end hi rez recording/playback chain using hi rez on the initial a-d.

However, I do believe based on the informal comparisons I have done that hi rez can offer a small but noticeable and worthwhile sonic improvement over RBCD.

So, I do not exactly yearn for ever higher sampling rates or a DAC to handle them plus all the additional hard drives I would need on my NAS to store the files. I tend to believe I am not missing anything, unless the laws of diminishing returns have been repealed. I have never heard DSD beyond 256 or PCM beyond 384k, my DAC's limits. I am really scratching my head about DSD512 or about ultra,ultra hi rez in general. The 31 khz spike is an idle tone in the Forte ADC, and the noise rise above 50 khz is the Forte. You'll see the HQ player is about 12 db lower in noise below 20 khz. In all of these FFTs the blue curve is the Foobar playback and green is HQ Player.įirst up silence to see the noise floor. Next I played the same 48 khz test file via HQ Player using the TC set to 192/24 as HQ Player upsamples to that rate. The DAC was the TC Impact Twin first playing a 48 khz test file with Foobar via ASIO. The ADC was the Focusrite Forte set to 192 khz/24bit. Okay had some time to kill so did a few measures with Foobar and HQplayer. Let people not complain about asynch USB. Somehow the Dell firewire port is causing high jitter and a higher noise floor in the TC Impact Twin. I ran the initial 48 khz natively in Foobar and it was also clean with low noise the second time on the Lenovo. There are some differences, but very, very minor.

I swapped as that software was already on the Lenovo. I was checking other software for playback and upsampling. After the first test I swapped places with the computers. I started out with a Dell laptop feeding the firewire lead to the TC Impact Twin. Leaving this here for now, but may delete it. It would be my opinion, if you want the best performing playback scientifically in a measurable way this is the software to use.

So this is some good software and Miska really knows how to make some good filters. You are of course upsampling lower rate PCM and playing it back at a higher rate, but the analog output was cleaner than the native rates, and cleaner than other upsampling software I have used. Using the -4 db white noise, and an IMD twin tone, and a silent noise file plotting the way JA does at Stereophile (what most people call a Jurgen plot) resulted in lower noise floors, less aliasing even somewhat lower distortion than any other filtering I have seen.

The manual gives a brief description of the various filter types for PCM. Usually you wish to use the highest rate available for your DAC. I thought the interface could have been a little better, and while it works well, I wasn't convinced I was hearing a difference. It will only work for 30 minutes in the evaluation version. This btw is an evaluation copy from maybe 18 months ago, but the settings I don't think are much different. I think Miska suggested his poly sinc filter as a good starting point and maybe his best filter for most purposes. Here is one where I had the Audiophileo feeding a 96 khz capable DAC. Depends upon whether you are doing everything DSD, or PCM or what your DAC will manage.
