If a DAC does some processing like dither and you tell it, it's 24bit

Even with fixed volume, its still 24-bit out of the SB...
If it's 16bit in with fixed volume it's essentially 16bit out.
Least Significant Bits will be 0, and that's what you are basically
telling the DAC, to ignore the 0's.

ZIP might, but audio compression works differently. FLAC for eample has
a run-length block type but that is to deal with identical samples, i.e.
digital silence. There's no case to handle this kind of pattern and I
don't see why you'd want one - if you think that

Sorry Sean the files will come out about the same. It does recognize
essentially zero net new content. A huffman code scheme would do it.
I did flac to flac to assure it's using the same version of flac.

Interesting... although I'm still not clear as to why it works. FLAC
uses rice coding on a sample-by-sample basis, not a general

for audio). Makes me wonder if it's handled as a special case...

Radish is correct. The SB and TP internally upscale to 24-bit regardless
of input bit-depth as part of the internal volume processing and they
always output 24-bit via spdif if using an external DAC. Therefore there
is no point at all in changing 16/44.1 files to 24-bit. It really IS a
waste of
Agreed, just for fun I ripped an album with dbpoweramp in 24 bit. The
files got huuuge, but there was no difference in sound quality.

Does changing the bit depth on ones 16.44 flac files make a difference
to sound quality?
The reason I ask is that over on the Lavry forums, they recommend
setting bit depth at 24bit regardless of what files you are outputting
to get best sound quality from ripped CD files through

You can't add what isn't there in the first place.
PROCESSING audio at a higher bit depth is one thing, there is less
chance of less that way, but ripping at a higher level that the

I fail to see how this could possibly work, since by default a spdif
stream is 20 bits (not 16 or 24) with the LSB 4 bits set to zero. Sure
you can set the extra 4 bits to zero making 16 bits of music and 8 bits
of zero but... WHY?
Don't know why - my secondary
Squeezeboxes always output as 24-bit, because of the volume control (if
the volume is set to 100% the LSB is of course 0). There's no reason at
all to touch the files (unless you have disk space you need to fill up).
