Hi,
I'm on latest moode, my source is on a NAS wav files with 32 bit pre-convolved with ConvoFS.
If I resample everything in ConvoFS to eg. 176400Hz, I'm getting under audio information:
encoded at: 32bit 176,4kHz Stereo PCM
decoded to: 32bit 176,4kHz Stereo
Output rate: 32bit 176,4kHz Stereo
So everything fine.
When then resampling with SOX on the Pi 3B+ 64bit kernel to 352,8kHz I get Output rate: 32bit 192kHz Stereo.
Why?
Other game:
If I resample everything in ConvoFS to eg. 352800Hz, I'm getting under audio information:
encoded at: 32bit 352,8kHz Stereo PCM
decoded to: 32bit 352,8kHz Stereo
Output rate: 32bit 192kHz Stereo
Why?
My goal is to set everything in ConvoFS to 32bit wav, 352,8kHz and my moode rpi is doning nothing expect playback.
This is because my DAC is internally upsampling everything to 8x samplingfrequency - but with SOX it sounds better then with the upsampling from the DAC.
A worse but also possible solution would be to set ConvoFS to 176,4kHz and let the moode RPI SOX do the step to 354,8kHz.
But none of the 2 possibilities is working at the moment from the audio information tab info.
Audio device is generic-1, I use an allo isolator, allo Kali reclocker, 3 more Hardware reclocker and then with I2S direct into my AK4497 DAC chip.
It does not change anything when switched to 24 bit wav or flac files, also 32 bit kernel no change.
Hope you can help.
Thanks,
Erich
