What do you think makes NOS sound different?
As you know, our test files are produced via the PGGB upsampling software. This is because it’s the highest performing audio resampling filter of which I’m aware. My only reservations regarding the PGGB have been it’s cost, which reflects it’s performance. (A quick aside, if you recall, our thread members are generously offered a 50% discount by ZB, author of the PGGB). Plus, the fact that it’s extreme performance necessitated it work offline. In other words, it doesn’t support real-time streaming content, such as from disc or the internet.
First, a disclaimer. I believe the below information to be correct, however, the responsibility is on you to verify all details. That said, ZB has just released an essentially real-time version of the PGGB, and which functions as a Foobar2000 plug-in. Even better, this Foobar version is free for download and use! So, you now may upsample, downsample, dither and experiment to your heart’s content, and at no cost.
As I understand it, the main performance limitation here is the maximum number of filter taps. Which is ONLY 2-million, in the free version. If you desire, a license may be optionally purchased which expands the maximum filter taps to 1-billion. For reference, the offline version PGGB supports a maximum of 8-billion taps. Ridiculously large figures for an interpolation-filter in either case. It’s an effective business strategy when a company manifestly believes in the benefits of it’s product. No risk for potential users to find out what PGGB technology may do for their listening enjoyment. Enough talking by me. Below is a link to the ‘remastero’ website with the intriguing details.
