You can create virtual RAM easily with Automator app (that's what I do) - very simple instructions could be found online. Or, there was a small free app called RamDiskCreator (could be not free anymore). jamesg11 1 Link to comment

Eventually, how soon? My new Mac Mini with M1 arrived yesterday. Sooner than what Apple promised. We'll see how soon I can get the build done. asdf1000, Mahler and Bach on Computer, perpetualapprentice and 3 others 6 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

We'll see how soon I can get the build done. It's just an unsubstantiated leak for now, but there's talk of an Apple M1x chip coming next year that will have 12 cores - 8 high performance cores and 4 high efficiency cores. That's 4 additional high performance cores compared to the current M1 chip. Additionally, since Apple introduced the M1 in their lower priced Macs, I imagine that there will be even higher performance chips (something likely named M2... and beyond) on the roadmap. I expect that someday there will be an Apple Silicon Mac Pro desktop that is focused on maximizing raw performance with no concern for battery life. We are currently limited to the (absolutely incredible sounding) EC DSD 256 with all of the current CISC, Intel & AMD x86 chips. It's unknown right now if the M1 chip can get us beyond that plateau, but even if it can't, I'm hoping that an HQPlayer optimized for the RISC Apple Silicon can at least run EC DSD 256 with relative ease compared to the x86 chips. That would be a great sign, given that the current M1 is Apple Silicon's floor, not its ceiling.

mirekti Posted December 2, 2020 Share Posted December 2, 2020 I am using Roon and have two PC stations each with HQPlayer. For some reason I am not able to put those two in the same zone and play simultanuosly. Is this a limitation of HQPlayer, Roon or something else?

MikePid Posted December 2, 2020 Share Posted December 2, 2020 I wonder if the M1 Mac will still be limited to outputting DoP, meaning to use DSD256 you need a DAC that supports PCM equivalent to DSD512? Link to comment

Yes it will be same way. There are no changes in macOS that would change this. Hardware itself won't matter in this respect.

It is limited by Roon, possibly because they have no way to force synchronization between the two instances. With HQPlayer, you can do this with something like RAVENNA, and each DAC would stay in sync to fairly high degree.

Client could work without too much trouble yes, mostly on iPadOS (because the larger screen would fit the GUI design better). But on the other hand, I don't see much reason for focusing on phones, because HQPDcontrol is good and already available for both Android and iOS. In addition there's no way to distribute software for iOS without going through Apple's App Store. bibo01 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Yes, I would say it is pretty certain they will produce bigger chips. Maybe without all the extra blocks, because now they burn so much space on those instead of CPUs. So likely they'd have separate CPU and GPU. And move the AI blocks to the GPU as well. 1 hour ago, k6davis said: We are currently limited to the (absolutely incredible sounding) EC DSD 256 with all of the current CISC, Intel & AMD x86 chips.

We'll see, I'm not holding my breath given performance of other 64-bit ARM CPUs. In the end this is just a low power category chip, similar to the Intel's U-series Core chips.

Yes, I can imagine special cases where specific hardware blocks are used it can be nice. But there are no special blocks for HQPlayer cases, so it will be solely on the CPU.

Zauurx Posted December 3, 2020 Share Posted December 3, 2020 New desired feature : automatic choice of modulator ?? I explain: I am happy with 4.80. Now I can use HF convolution directly in HQP with HiRes and DSD under my i5-470. Before that was impossible for me .. dropout every 2 sec. I was forced to process the convolution under Roon. Too happy... I let myself try the ADSM5EC. It will crash !! Well no ... now it's okay !! I try ADSM7EC .. it will crash !! Well no .. CPU at 85/90% but it works. Thank you !!! 😊 On the other hand, impossible to pass in input a HiRes or DSD file. So the idea, as for the 1x or Nx filters : automate the choice of modulator according to the input signal. ADSM7EC for all 44/16 and ADSM7 for everything else (DSD direct or HiRes - 88/96, etc.).

But this is just me hypothesizing.....I have no idea if this is even possible. HQPlayer doesn't use any ML/AI stuff, it is not useful for what HQPlayer is doing. For AI purposes for example Nvidia added support for 16-bit "half precision" floating points. And even more there are added things for even lower resolution calculations like 8-bit needed for AI inference. While HQPlayer things go to opposite direction, using minimum 64-bit "double precision" floating point. And on Intel/AMD CPUs there is luckily still the x87 FPU hardware support for 80-bit "extended precision" floating point which is also extensively used by HQPlayer. It is possible to do up to 128-bit floating point through software emulation, but it has big impact on CPU load.

So is the benefit of the CUDA offload dependent on the FP64 performance? Most of the consumer GPUs have low FP64 performance as that's not needed for either gaming or machine learning.

SwissBear Posted December 4, 2020 Share Posted December 4, 2020 Hi everyone, A short update on my experience with the M1. First, I was intrigued by this post of Miska: and I decided to measure the tension on the STP cable I had on my Mac Mini M1. And this was 30V :-( So there seems to be a serious leak of current from the PSU on this device... which makes me expect the kit of @Superdad next year... This led me to generalize the use of UTP cables at home. Thanks @Miska Otherwise, the listening experience with HQPlayer is very smooth. On most music files, the combos DSD256/ASDM5EC and DSD128/ASDM7EC are very smooth. I am still very much looking forward to the native version, but I am quite impressed by what I am hearing so far...

voxel Posted December 5, 2020 Share Posted December 5, 2020 Hi @Miska, What's the recommended way to access HQPlayer from players other than roon, like JRiver, Audirvana or foobar2000? From description in HQPlayer embedded version: It can operate for example as a digital-in-digital-out upsampler processor and convolution engine, or used inside a DAC It can also function as a UPnP AV Renderer There is also support for the HQPlayer Control API that can be used for implementing a custom GUI or other type of front-end utilizing the HQPlayer playback engine Does roon use the control API and do other players have to access it as uPnP AV renderer, and can they use desktop version? Appreciate your help! Regards, Yongsheng Link to comment
