Hello,
Possible in same time transcode different freq type of files:
44.1/88.2/176.4 up 352.8kHz
48/96/192 up 384kHz
Now all files transcoded up 352.8kHz, but i cant hear any SQ difference from 48/96/192 up 352.8kHz.
Thank you

You can do this by using
input type filters. For example, this setting for stream.transcode does what you want for FLAC files:
flac(44):wav;352, flac(88):wav;352, flac(176):wav;352, flac(48):wav;384, flac(96):wav;384, flac(192):wav;384
Transcoding to a higher sample rate can't add musical information that isn't present in the original file. A 192kHz recording will sound better than a 48kHz recording transcoded up to 192kHz. Depending on your setup and your streamer/DAC, you might hear a slight improvement from transcoding or you might not.
Hello,
Like My DAC, i love everything to 24bit:
flac(44):wav24;352, flac(88):wav24;352, flac(176):wav24;352, flac(48):wav24;384, flac(96):wav24;384, flac(192):wav24;384, dsf:wav24;352.
Transcoding add air to my system, its better for internal clock too
Thank you

I'm pleased to hear that transcoding/upsampling is working well for you. What streamer/DAC do you have?
