Using Plexamp on an iBasso DX180, which supports DSD and high res playback. High res flac files play just fine, at the proper sample rate (unaffected by Android’s 48kHz resampling). The same files play fine with other media player apps (USB Audio Player Pro), confirming that DSD is supported on th…

Interesting, it seems to be failing because you’ve enabled sample rate matching and it can’t switch to that sample rate: Nov 03, 2024 12:47:58.581 [0xd9bbbcb0] ERROR - BASS: Error initializing device 1 with sample rate 352800 and flags 00004000 (6). We decode and don’t passthrough the DSD, because…

That rate should be supported by the DAC and it does work with another app (PCM transcode). Any possibility of adding the ability to pass dsd without transcoding?

[image] benjamindaines: Any possibility of adding the ability to pass dsd without transcoding? Sorry, no. Our pipeline depends on having PCM at the base.

How about support DOP send from server to endpoint? DSD over PCM

Does this mean that plexamp will never be bit perfect?

It’ll be bit-perfect for “reasonable” codecs :sweat_smile: And your ears won’t be able to tell the difference with DSD, let’s be honest.

Well, I’ve set up my DAC/amp and am listening to dsd512 audio and comparing it to CD quality audio, and there is definitely a difference. Moreover, yesterday I took time to compare 192/24 audio running through plexamp vs musicbee, and I was very surprised to discover, it’s not just a miniscule diff…

I don’t believe there is scientific evidence for any perceptible difference. Like you imply, the mind is a powerful thing, which is why ABX testing is generally the go to for such comparisons.

without Plexamp logs, impossible to hazard a guess.
