In a thread on the ripping forum recently, mswlogo has sussed out how to
'up-bit-depth' his flacs from 16 to 24 bits. Filesize is similar, as it
just compresses out, so no downside. The file is padded out with
zeroes, so there is no change

I don't see how simply having more bits (with no information in them)

higher bit rates, since everything is happen faster if you see what I

Jitter will be exactly the same. The SPDIF spec transmits 32 bits of
data per sample anyway; up to 24 of these are available for the sample

If your going to upsample as well doing it in larger word length is more
accurate (some would say a better guessitmate). Upsampling doesn't make
a lot of sense with Slimdevices because SB3 only does 48khz and
Transporter doesn't do 88.2Khz. BUt my library is for other devices

I must admit, I don't know for sure why the test results are different -

What I was getting at, is that your DAC, or your processor, or whatever
else is connected over SPDIF, simply won't know whether it's getting 16
bit or 24 bit data. The SPDIF frame includes 24 bit positions for use
with audio data, and a source that only has 16 bits available simply
pads the

Stereophile's jitter measurement in this case is just nonsense. They

The volume function is always 24 bits wide. It doesn't know or care
whether the lower 8 bits are used, and all 24 bits of output are
meaningful regardless of the input word length.
That's
yes any static normalisation is a bad idea, regardless of how many bits
you have to play with. The engineers did their best to master your
bits...do not mess with them - you will not make them better - only
