Feature request FLAC
Dear all,
I am an active FLAC user and like the program a lot! Thanks for your
great work. Since I am not a developer I cannot modify the program on my
own.
Maybe you might be interested in features I would find useful. Maybe others
find them interesting as well and you find the time to implement them.

a) Skip silence (leading and ending) would give the option to skip

FLAC utilities for Monkey's Audio GUI: useful?
FLAC solution for MSVS contains two projects: flac_mac and flac_ren.
They are intended to work together with Monkey's Audio GUI frontend

Questions about bitrates
If I understand correctly, Ogg Vorbis is a lossless format. But then why
does it support bitrates?
Ogg Vorbis does not delete any information. When I encode a 128 kbit MP3
file to 32 kbit OggVorbis,
the resulting file has a bitrate of about 110 kbit.
And when I encode it to 320 kbit, the file will be bigger, but the quality
won't improve because
of the quality of the original.
So what purpose

More than 150 MB / second encoding ?
Hello,
Is there some version of FLAC that allows very very fast encoding (i.e.
able to process at least 150 MB / second of .wav input data on a standard
computer : laptop computer, Core i5/i7, Windows 7 64 bit, 8 GB RAM) ?
(It's ok to have a compression ratio which is a little bit lower than
traditionnal FLAC)
I'm looking for something which is between FLAC (very good ratio, slower

[bug] --keep-foreign-metadata discards WAV cue markers
Hello,
I noticed that option --keep-foreign-metadata discards WAV cue
markers. Here is how to reproduce the bug:
1) Create a 24-bit 96khz in SoundForge8, add 20 seconds of silence,
and add two markers with "m" key shortcut
2) Save it, compress it with "flac --keep-foreign-metadata testmarkers.wav"
3) Decompress it with "flac -d testmarkers.flac"

lossless compression's limit : 53% ?
Hello,
What is nowadays lossless compression's limit (tested on a large library of
music samples, because of course, it depends on the music we do the tests
on) ?
I often see 53% - 62% of original WAV file's size. (
https://xiph.org/flac/comparison.html )
Are there algorithms that can losslessly compress to, say 40% of original
WAV file size (I don't mind about encoding time here) ?

More than 150 MB / second encoding + "nanozip"
Thanks for the info. I will look at encode.ru .
In the meantime I discovered "nanozip" : http://www.nanozip.net/
On http://compressionratings.com/sort.cgi?aud1.brief+4nf_pf, the result is
amazing : 100 MB compressed in ... 0.44 sec !
with compressed size = 60% of the original size !
i.e. ratio = similar to FLAC, and very very fast...

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'

I vote for #2.
I don't see the options in #1 as strictly going with the philosophy of FLAC
being a lossless codec although neither one seems like a bad idea if
implemented properly. More generally part b of #1 would allow you to select
any channel(s) from a source and just encode those channels. For example you
may want to encode only 3 channels of a 4 channel source or 5 of 8 or 1 of

I am not an expert on the guts of FLAC, but
there is some information about this at:

FLAC algorithms
Hi,
Is there some documentation available about the algorithms FLAC uses?
I'm talking about some high-level descriptions of the algorithms, which I
can read without having to understand the source code.
thanks in advance

How is the MD5 hash calculated?
is it on a per subframe basis, and if so, is each frame padded if it’s not a multiple of 512 bits? or do I have to decode all the data, and run it over the decoded file at once?

Educational App Problem (4nec2x): Fail When 3d Window Closed

Deployement options
After reading the digital shortcut and the
documentation on the web site I''m confused.
Which one should I use? pen, balance or nginx ?
I don''t want to use a behemoth like appache and ssl is
not needed so it reduces my choice to those three
only....
What are the pros and cons of each? I don''t have much
money, so the less ressources I use the better it is
for me....
