PGGB - upsampling with billions of taps

[Don Hills]

My first thought on reading was "Oh no, not again..."

remastero - PCM reimagined

In short, it's a tool for upsampling to the maximum rate supported by your DAC using filters with millions or billions of taps.
There's a thread over at Audiophile Style. Extraordinary claims made...

 

[mansr]

I can do better. I can resample using ALL THE TAPS.

 

[Eetu]

You get to use 8 Billion taps but for only $500. What a bargain!

I do hope they are paying the appropriate royalties to the Douglas Adams estate.

Because of the infinite improbability that it does anything useful?

Mathematically designed, subjectively voiced...

 

[JSmith]

Are these the taps you speak of?

I tapped on the video , It's blocked and does nothing. Much like the device in question

 

[JSmith]

It's blocked

Seems that one needs to watch it on YT rather than embedded, apologies;

Playback on other websites has been disabled by the video owner. Watch on YouTube

Jerry Mouse and Gene Kelly Dance - Anchors Aweigh (1945)

Probably not the taps we speak of here I guess...

I think they’ve had one too many Pan Galactic Gargle Blasters.

Oh no. Please tell you made that up? Otherwise I will be helplessly driven to look at the site.......Resistance is useless

 

[abdo123]

can someone explain to me why such devices exist but a standalone MiniDSP-esque device capable of FIR filters with 65536 taps does not?

My attempt to save you, since I've already seen it and can't unsee it:

While remastero's algorithms were mathematically derived and further optimized using simulations and measurements, they were voiced and refined through subjective listening by a group of audio enthusiasts who share a common passion for realistic and natural reproduction of music.

The short answer: money.

A few hundred taps is all you realistically need.

 

[abdo123]

A few hundred taps is all you realistically need.

that's still few hundred more than the device in question.

 

[pkane]

A simplistic FIR filter implementation only works with a small number of taps. I assume, the device in question doesn't have enough processing power to handle a larger filter or the designers didn't know how to optimize for a larger filter, or had assumed that this wasn't necessary.

What device are you guys talking about? The subject of this thread is, near as I can tell, a piece of software meant to run on a powerful PC.

I think it was about MiniDSP, and unrelated to this thread

Interesting that PGGB needs oodles of memory to execute, even though it's an off-line resampler.

If this was FIR, it would have a huge delay as well right? So it must be IIR...
