Upscaling or Upsampling ETC

[Hans_Van_den_Bent]

Hi community,

Yesterday I met a guy who used the Chord Hugo Mscaler (kindofpricey). Does this upsample or upscale the signal?

He was puzzled why I liked native DSD. Maybe because there is no upsampling/upscaling possible with that? Anyway, I like the DSD sound.

Regards

Yes, that’s what it does. In theory, it is possible to up-sample DSD, but that would be useless.

[Hans_Van_den_Bent]

Sorry, but that is NOT my point. I like DSD because it is what there is. No upsampling etc.

NEW TRY…is anyone using upsampling of PCM or upscaling (using a Chord or Grimm MU?)

Yesterday I met a guy who used the Chord Hugo Mscaler (kindofpricey). Does this upsample or upscale the signal?

From Chords website:

“The Hugo M Scaler is a highly advanced standalone upscaler capable of redefining sound quality from digital audio. It uses Rob Watts’ (our Digital Design Consultant’s) unique filter technology, the most advanced in the world, to upscale standard 44.1kHz digital audio up to 705.6kHz (16x CD’s 44.1kHz native resolution), ready to be passed to a suitable DAC; Hugo M Scaler extends its upscaling performance to 768kHz (from 96kHz input data) for our dual-BNC-input DACs: Qutest, Hugo 2, Hugo TT 2 and DAVE.

The Hugo M Scaler brings the unrivalled advantages of our ground-breaking FPGA-based WTA (Watts Transient Alignment) filtering technology to digitally connected audio devices, dramatically improving sound quality. Although optimised for use with selected Chord Electronics DACs (for the maximum 768kHz upscaling/decoding benefit), the Hugo M Scaler can be used with other DACs with suitable inputs, subject to their decoding capability.

The Hugo M Scaler’s compact form factor aligns with the TT (Table Top) series and has been designed to be stackable with other units in the range, including the TToby stereo power amp and the Hugo TT 2, to form a highly advanced yet space-saving system. In line with other models in the Hugo and Hugo TT series, the device features a number of illuminable fascia-mounted spherical controls, governing input selection, output sample rate and video mode for lower latency. The control spheres display data visually including input source and the incoming sample rate, using a polychromatic scale.

When partnered with either of Chord Electronics’ 768kHz-capable dual-BNC-input DACs, the Hugo M Scaler sets an astonishing technical benchmark for digital audio performance at it price point, redefining sound quality from digital audio.”

There are plenty of folk doing software upscaling using HQPlayer on a dedicated thread. Or is it upscaling hardware in particular that interests you?

[QuinnT (BANNED)]

Arguably, HQPlayer can offer superior upsampling than the Hugo M Scaler according to some sources?

Yes, that’s what it does. In theory, it is possible to up-sample DSD, but that would be useless.

Are you sure? Have you checked out the HQPlayer DSP upsampling algorithms?

[Menzies]

This might be of interest

DSD resolution

[Marian (I stand with Ukraine)]

To be clear, I’m talking about up-sampling DSD to DSD, not PCM to DSD.

[QuinnT (BANNED)]

Yes, I understand completely. I ask you the same question again:
Have you checked out the HQPlayer DSP/DSD upsampling algorithms?

[Marian (I stand with Ukraine)]

There must be a point in there somewhere… Can you help me find it?

[QuinnT (BANNED)]

@QuinnT

Delta-Sigma modulators for upsampling PCM/DSD content up to 98.304 MHz 1-bit SDM (14 modulators, 49 PCM oversampling options and 3 DSD rate converters)

And more … if you can read it

[Marian (I stand with Ukraine)]

I did say it’s possible, right? I also said it would be useless and I stand by my statement.

[QuinnT (BANNED)]

it’s not useless, whether it makes your system sound better or worse is another matter.

Why Hi res - an updated view

Pretty sure he explains what it is about.
