I have a problem with my NPC and do not know the cause. My PC is working under Windows 8 and I write and save files as PCM 24bit 192 kHz wav. My NPC is using firmware version .46. Recorded files play and look fine, but not long ago I noticed that when encoding files in flac the files size is less than other similar files compressed in flac (approx 1/2 the size). Now I think that the recorded files are not really 24-bit and contain only 16 bits of actual data. All the system settings on NPC and PC are correct. I tried three different recordings software - Sony Sound Forge, Audacity and Vinyl Studio but the result was the same. I also tried different USB cables but nothing changed.
I did an archive for these 3 files:
and one file taken with analog output of my NPC and recorded with RME soundcard for comparison:
Has anyone noticed this with their NPC? Perhaps other users are not aware of this issue.
I’ll be happy for any help
P.S. By the way I tried record in 24/96 but the situation is the same.
