flac-dev Digest, Vol 149, Issue 5
Can you guys clarify that by Rice you don't mean unary coding, but
exponential golomb coding?
that issue has confused me before, and probably others.

[Cellar] FLAC Markdown
Hello all!
(cc-ing the flac-dev list)
I would like to give an update as to the recent CELLAR work on the FLAC
specification.
• Work has been done to make internal and external links more accurate and
reliable.
• 'Rice Coding' has been clarified as 'Exponential Golomb Coding.'
• Clarifications have been made for binary representation.
• Typos and other small changes have been fixed for clarity.
Lastly, a version 00 release has been made (available at
https://github.com/privatezero/flac_markdown/releases) and the draft
document has been uploaded to the IETF...

The residual is stored as a Golomb/Rice code. As far as I know,
that is not limited to 32-bit in the format itself, only in the
implementation.
However, there are two residual coding methods now: rice and
rice2. rice2 was added when it turned out rice (with a 4 bit
rice parameter) wasn't able to cope with the larger residua...

FLAC: compressing data
...ny input will work
correctly. With music data, most algorithms rely on the fact that adjacent
samples are close to each other in value, so flac works out an equation that
fits the data closely, then relies on knowing that the error (the residuals)
are small, so it uses a nifty encoding scheme (Golomb-Rice I think) using
extra 'padding' bits at the start to efficiently store the small numbers
without needing to write the leading zeros as well. This process will work
on any data, but for most inputs the output will probably be a bit bigger, as
the polynomials will not fit the data we...

NHW Project and wavelet codecs
...ember the author post
there is furthermore an interesting fast context modeling based on the 2x2
variance of wavelet coefficients in order to reduce the context cost per
coeff, associated with an also interesting range coder (division-free) that
can be skipped to code raw bits or with huffman, rice-golomb... Wavelet
transforms, SPIHT, context modeling have improved since 2008, so why no new
updated wavelet codec, as it was the case of HEVC for H.264 (Rududu is
similar in performance with x264 intra, PSNR- and SSIM- wise)? -Do wavelets
have so much bad reputation?-
Ok that's right the NHW codec...

FLAC: compressing data
hi
can the flac encoder be used to compress non-wave data? So suppose I rename
a data file to *.wav, can i compress it then using the flac encoder to make
it smaller?
just wondering if this is possible

NHW codec - progress 2
Hello,
Just a quick message to correct what I have said in my previous post.It
finally seems not that easy to code small wavelet coefficients to have a
good precision, and SPIHT is certainly a very good algorithm for that, -and
I know there are SPIHT experts that can make very good SPIHT-based
codecs-.I have chosen a new and different approach, the multistage residual
coding, so I will try to

audio data encoding in FLAC: how complex ?
Hello !
The following algorithm describes Golomb(=Rice?) encoding:
http://en.wikipedia.org/wiki/Golomb_coding#Simple_algorithm
What is unclear to me is how many audio samples
encoded with a fixed parameter (denoted 'M' in the wiki,
which i presume is equivalent to the 'Rice parameter'
invohed here):

Supporting 32 bit data
Hi all,
I just noticed this:
https://sourceforge.net/p/flac/feature-requests/91/
a request for support of 32 bit audio data. The request has been around
since 2008.
Had two inial impressions:
* Would adding this break brackwards compatibility too badly? Obviously
decoding of 32 bit encoded data would not work with older versions of
flac.
* This is nuts. 24 bits has a dynamic range of
