Loud Crack When Starting DSD Upsampling

Studio
1

Hi,

First post as a trial user of AS, I’ve noticed an issue if I choose to upsample my tracks to DSD128+ with my Topping DAC and ASIO driver. It appears that the software drops back to dsd64 between play sessions, then with the jump to a higher resample rate when playback starts, there is an audible crack, not to dissimilar to a needle hitting vinyl.

The options to mute or add latency don’t appear to be active for DSD. Roon and JRiver don’t exhibit the same behaviour. PCM upsampling is fine even with those options off.

I noticed a 4 year old topic with the same issue, so has this never been fixed?

Cheers

Try adding 1.5s of ‘Sample rate switching latency’ and lowering your playback pre-load RAM allocation to 2GB and turn-off software volume control… Also, I suggest removing JRiver Media Center for best performance.

Makes no difference sadly.

The dac options to add extra time are greyed out in DSD upscale mode.

RAM/Uninstall Jriver made no difference.

It’s easily repeatable just by jumping between a radio station and then a local file, or when first playing a local file from start up. Looks like it’s never been fixed.

Also noticed it’s missed 500 tracks on the import too, must be an unsupported format from decades ago.

Shame as the gui as the gui is nice.

I modulate all PCM files to DSD128 via r8Brain in Audirvana and the Sample rate switching latency setting is fully available to me on macOS…

When the sample-rate changes from PCM to DSD or from DSD to PCM there can be a transient level change pop or tick…
