Hello Guys,

is there anyone here having a 20-bit wav-file, sampling frequency can
be just anything. I need this to see if a piece of software is treating
a 20-bit wav file correctly and see whether it outputs the right audio?
Content is not relevant.

If anyone could help me with this I'd be very grateful.

My understanding is that a 20bit data stream
actually uses a 24bit word length.
So there would be no difference in the file
itself other than the zeros in the LSB's.

No such thing as a 20 bit wav file. 20 bit ADs record into a24 bit file.

Thanks guys,

yes, as I understand it, the 20 bit wav-file is made by padding the
last 4 bits with zeroes.

But, what about an .aiff-file? Anyone having a 20-bit aiff file?

The thing is, I want to make a DVD-Audio disc with a 20-bit track and
it is possible, in DiscWelder, to import 20-bit wav-, or aiff-, files.

Or, if you know any other way of achieving this, I'd be also very
grateful.

What I want to have is a non-encrypted DVD-Audio disc with one track
with 20-bit resolution.
