    Bit depth confusion

    I have version 16 of dbPoweramp. Under DSP tab the fixed bit depth is set at 16 bit. I have ripped my CDs as flac files with this 16 bit setting.
    I have just purchased a Benchmark 3 HGC DAC and its indicator lights say it is receiving a 24 bit depth stream. Is there a problem with dbPoweramp? or could just be a problem with my new DAC?...which I feel is unlikely.
    All helpful comments will be appreciated.

    You can see the bitdepth of any ripped file by holding the mouse over it, the yellow popup will show bit depth. The value shown is 100% reliable for lossless files.

    What player are you using? For example, I use LMS and it converts* all files to 24/44.1 and uses the extra 8 bits to do digital volume management, etc. without impacting the lower 16 bits (that contain the audio). I suspect your player is doing something similar.

    * by convert, I don't mean that it touches the files themselves. They remain lossless 16/44.1 files. But LMS *streams* the files to my DAC as 24/44.1. Roon does something similar and I think even foobar2000 has a setting for this. So it's not unusual.

    garym...thanks for your comments: I am using a Sonos Connect to stream to my Benchmark 3 HGC. On this basis my Benchmark 3 cannot really tell me whether it is receiving a 16 bit music file or a 24 bit music file can it?
    Could it be that all 44.1 kHz files are 16 bit depth anyway? Hope I make sense...

    If this was truly a 24 bit file, Sonos wouldn't even play it as SONOS products won't play 24 bit files...produces an error. (but I suspect the Connect then produces a 24 bit *stream* from the file to handle digital volume)

    No, not all 44.1 files are 16 bit. It is possible to to have a 24/44.1 (just like it is possible to have a 16/48 or 24/96 or 24/192, etc. But a regular redbook (normal) CD is *always* 16/44.1. As spoon noted, it is easy to confirm your ripped files are 16/44.1. Right click on a file, then select properties, then select "audio properties" tab. It will tell you the sample rate and bit depth.

    I'm curious. Why are you using a "bit depth DSP" when ripping? This is not needed if ripping a regular CD. Such a rip will be 16/44.1 automatically.
