I'm scratching my head with the Shanling Music app reporting incorrect sampling rates in DSD files.
Actually, I'm making my own DSD files with a SoX fork for experimentation purposes--seeing if bypassing the internal oversampling filter and replacing it with a 16-million tap sinc filter run by my PC yields any benefits. The general workflow is to use a 16.8 million tap sinc filter to first upsample the FLAC 44.1kHz file to WAV64 at 24bit/2822.4kHz, then convert the WAV64 to DSF. EDIT: After further investigation, the intermediate conversion to WAV64 is unnecessary and the files can be directly converted from FLAC to DSD using a single noise-shaping filter, in case anyone else is interested in trying this (github.com/mansr/sox).
Packages like mediainfo and soxi show that the files have the correct sampling rates, e.g.:
...but when I play the files back with the Shanling Music app, I see a variety of sampling rates: one album has the correct sampling rate of 2822.4kHz, some show as 1411.2kHz, but most show up as 357.8kHz. Regardless, "DSD64" displays in the top right corner. I am using the exact same script to make all of the DSF files, and all of the albums are originally 44.1kHz. Other devices and apps recognize the files as having 2822.4kHz sampling rates, only the Shanling Music app gets this wrong.
I know it's probably silly to ask if anyone else has experienced this given the niche nature of what I'm doing, but can anyone possibly shed some light on this for me?
EDIT: I'm not sure what happened, maybe Shanling updated their app just now, because all of the files now show 2822.4kHz. Files that used to be DSD256 but are now DSD64 (I couldn't tell the difference) still show the DSD256 sampling rate of 11289.6 kHz, but the app displays DSD64 in the top right. Either way, the problem seems to have gone away.
DSD64 sounds amazing through the M8, by the way! I've converted a hundred or so of my favorite albums and am re-listening now with the M8 as a DAC > Bottlehead Crack (supermodded) > HD800 (SDR+Anax). Separation, dynamics, and resolution are all improved; instruments are more textured and sound more natural; all around cleaner and clearer sounding than the PCM versions.
