That seems to be correct. As @pm325 has explained to me, for DSD upsampling studios use one of two approaches: internal conversion to DXD (Pyramix DAW) or to DSD-Wide (Sonoma DAW). Neither is bit exact as each sigma-delta modulation step adds additional HF noise. Algorithms with 64-bit floating point resolution may reduce errors. Only HQPlayer Pro seems to use internal processing within the DSD domain. All a bit too technical for me. I tried the trial version of HQPlayer Pro and it did produce DSD256 files. However these would not play. Surely my bad, but I was not as persistent as I usually am, knowing that I could not afford the licensed version anyway. So back to just using my ears and skipping the technical details. Happy with EZ for now. jamesg11 and motberg 2 audio system Link to comment

Yes, DSD64 to DSD128 (or higher) includes conversion to DXD. The user interface displays "DXD" when the files are converting. Link to comment

Yes, and this stellar PC is bound to produce noise that lowers the SQ in a single PC setup. A solution would then be to separate this PC from a Spartan audio endpoint with NAA in a 2 box setup. However, this requires network that again adds noise. Which needs to be minimized using expensive routers, switches, an audiophile network card, fiber etc. More dollari / euri... Hence my great recent relief to skip the network altogether and play from a lean fanless SATA-less wtfplay endpoint. It beats my previous 2 box setup. A lot of money spent to no end, but that is the beauty of this hobby. motberg 2 audio system Link to comment
Undertone Posted June 24, 2020 Share Posted June 24, 2020 One solution that doesn't cost a lot of money is a licensed download of EZ CD Audio Converter. After testing the trial software on hi-res PCM albums and DSD64 albums, I purchased it today. For me, it's a very inexpensive and efficient alternative to converting PCM=>DSD128 on the fly in Audirvana. bodiebill 1 Link to comment
bodiebill Posted July 5, 2020 Share Posted July 5, 2020 Another good option is xrecode3: https://xrecode.com/ I think I prefer it to EZCDAC for upsampling DSD64 => DSD256. Anyone else using this? rando 1 audio system Link to comment

I used it to some file conversion from various other lossless formats into wav as well as some trials with DSD. Can't remember if I did any DSD64 to higher rates. For sure tried making DSD files out of everything from mp3 to DXD. After sampling the alternatives I was happiest with results out of this program using the current at the time version. Not sure I like how often it gets updated or if this sentiment would apply to the current version. Main use I've found for it was rescuing ISO from SACD that ISO2DSD didn't like. Which it did admirably leaving me to wonder as to source of corruption XRECODE was able to deal with. Rather than drive myself crazy I just sat down to listen until the worry melted away.

rando Posted July 8, 2020 Share Posted July 8, 2020 I had a look at the recent changelog. @mansr's SOX is implemented as of version previous. Good to see him getting well deserved recognition. Going to try v. 1.102 when I get a chance since it seems the updates are less worrisome than I feared. Link to comment
JCB Posted October 18, 2020 Share Posted October 18, 2020 Hello all ! I revive this thread to put the subject on a specific way. I am very interested by the Hugo M-Scaler which seems to have a very powerful and qualitative upsampling algorithm. But it is way too expensive for me, and I want to listen by myself what kind on results can be achieved this way. I wondered if a comparable algorithm (1 million taps) exists in an offline software ? I am not interested by standard upsampling or DSD upsampling : all DACS are doing upsampling or deta-sigma upsampling internally and reproduce these standard algorithm offline is not the point. I am interested by an offline upsampler, who does 1 million tap filtering (it will be very slow, but it does not matter) or does what a standard DAC or upsampler cannot do without expensive FPGA. Are you aware of this kind of software ? Link to comment

I don't see offline in the data sheet.

As far as I know, a PC cannot do 1 million taps upsampling in realtime, but maybe with Nvidia CUDA.. There are two HQPlayer “consumer” versions (Desktop & Embeded) that are real-time resampling only. I use HQP Desktop to convert all files to DSD256 format before file is sent to my DAC. The value of HQP is the ability to use a powerful computer to convert files to various formats using a wide select of filters and modulators. DAC’s just don’t have the same processing power to do the same. HQPlayer Pro is more for “professional” users that allows offline processing so that the new file can be saved. I assume it can do real-time as well but perhaps you can ask the developer @Miska who is very active on AS. Eric Audio System Link to comment

You can turn on/off the monitoring output on the fly as well. 1 million taps to 705.6/768k PCM (what Chord M-Scaler does) on my Xeon W-2245 is less than 10% CPU load, no need for GPU. So it is totally non-issue to do in realtime, even with regular CPUs. 32 million taps to 12 MHz is closer to the edge with Nvidia CUDA. HQPlayer Desktop has free trial, you can try it out yourself with sinc-M filter. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment
