Title: Stutters and cut songs
Post by: Maude on August 17, 2021, 11:59:41 am
Hi,

I have for equipment the following:

NAIM DAC-V1 with latest firmware for DSD64, fed by USB 3 from computer and outputs to Audeze LCD-GX. JRiver MediaCenter 28 latest version drives the show. Playing mostly FLAC songs.

On Media Center, I have the following activated: Parametric EQ with filters (low) at 50 (3DB) and 120hz (3DB) and a High pass at 3,5K for 2,5DB. Output is "transformed" to DSD64 for the Naim to play. There is also a convolution file that some Audeze tech produced that is active.

Now: when I play music (FLAC), the song "cuts" for a fraction of a second and comes back, only to do it later on, 4-5 times per tune.

I have set every single option about buffers (large ones), keep the song in memory, the whole nine yards, same on ASIO4ALL. I gave the application as much leeway to process the file fast and with time to spare.

My computer is a workstation with 32C/64T, 144 GB RAM, 3 NVMe and the music is on one of the NVMe. No accessing problems there.

Still, it is stuttering and cutting which is ruining the experience and gets aggravating.

I like the app but if it continues that way, I'll have to look at other options.

Anybody's advice will be appreciated.

Maude

Don't use ASIO4All.

Simplify what you're doing to see if you can find out where the problem begins.

You're doing a lot of processing and the files are big, so bandwidth could be the issue.

Won't I lose the DSD64 that my DAC is affording me by using WASAPI?

As well, I see in the first picture (the convolution screen) that I process that thing at 40x real time....

The computer is a powerhouse and quite up to the task I think, having 2 CPU's with 16 cores/32 Threads each. 144 GB RAM and NVMe SSD's should provide a clear path for the file to be read by the application.

I maxed out every setting that mentioned buffer.

I will try what you recommend and see.

WASAPI works fine with DoP, just not with native DSD sample rates.

Your CPU speed depends on how well things are parallelized. Try cutting out the convolution. Then do the convolution and outputting to flac.  The combination might be too much if it stays as a single stream. Worth testing.

Thank you all for your answers.

I'm just out of 45 minutes listening session and not a single hiccup...

Same setup, nothing has changed. The only thing I can see is that I'm not connected to the office through VPN. I wonder if this can affect JRiver at all but who knows.

Also ASIO4ALL isn't true ASIO, it's a wrapper for kernel streaming which is now considered legacy in modern Windows and was replaced years ago with WASAPI.

So Jim's right, ASIO4ALL should be avoided at all costs.
