Patch to add buffering to decoding too
Decoding flac files is also prone to producing fragmented files. NTFS
has the ability to completely avoid fragmentation if it is told the file
size before hand, but that would require using special Windows-only
functions. Increasing the write buffer from the default 512 bytes to 10
MB already reduces the problem tremendously.

Patch to add buffering to decoding too
Can you please wrap the setvbuf in _WIN32 IFDEFs too? Currently
memory usage of FLAC decoding is about 1MB, so this patch is
increasing memory usage tenfold, also for platforms that do not
need this. It is a non-problem on my system anyway.

[PATCH] Add appropriate WAV channel masks for 7 and 8 channel files.
This commit accepts the new default channel masks for 6.1 and 7.1
surround input WAV files, and writes the corresponding masks when
decoding to WAV without a channel mask from the metadata block.

Removed buffer size increase. Only tells the filesize to Windows now.

This is equivalent and just makes the code shorter.

test_metaflac fails in make check for flac 1.1.2 after --add-padding is performed
Josh,
I applied this patch and all the "make check" tests passed (but I do not have valgrind and I did not use --enable-exhaustive-tests during configure, so it isn't all the tests). Do you see anything suspicious about it?

Patch to add buffering to decoding too
I made some changes to the previous patch. I don't know why I originally
didn't put the output buffering to piped output too but that is now
moved to cover both file and pipe output.
Additionally this patch informs the Windows filesystem in advance about
the decoded size to eliminate NTFS fragmentation.

Your proposed wording was:

[PATCH] for flac/decode.c
The commit http://git.xiph.org/?p=flac.git;a=commitdiff;h=99257e177eac96fa41a107b423080232f59ebe45
also requires some changes in write_iff_headers() function:
currently flac don't write WAVEFORMATEXTENSIBLE header if
decoder_session->channel_mask is equal to 0, 1 or 3.
After the commit 99257e17 flac should do this for channel_mask
equal to 0, 4 or 3.
The patch fixes this.

First, regarding existing tools that I now about.

Calling for 5.1 Mastering experience! (vorbis ambisonics and 5.1)
I've been doing a fair amount of work with Vorbis support for Ambisonics,
which seems to be going along nicely. It seems that there is signifant
interest in coding 5.1 material with Vorbis esp as tarkin becomes more
complete, so I've decided to take a break from pure ambisonic work to look
into this.

I'm confused. WAV puts the rear centre before everything but 'Front
left of center' and 'Front right of center'. Are you saying you prefer
the extra front channels to to side/rear surround, or that you prefer
the MPEG order to the WAVE order?

Missing value handling for felm function in lfe package
Dear All,
I am trying to use the felm function in the lfe package. However it does
not seem to deal with missing values the way the lm function does. I wish
to tell it na.omit or na.action = na.omit but it does not recognize this. I
need to allow for missing values as I have different specifications and
don't want to remove observations for all. Help on this will be greatly
appreciated!

i didn't find anything about tagging flac files as surround files. i
think there should some possibility to tell the player how to play a
multi-channel file (how to map the different channels to the speakers or
if there some decode is needed, like for ambisonic files).
any idea how to implement it?

Multi-channel support
Hi All,
Are multi-channel (more than 2) formats fully supported in the OggVorbis specification ? I couldn't
find any information about multi-channel support on xiph.org. I've used 'oggdropXPd' to encode a
5.1 wavefile and the Xiph OggVorbis libraries (vorbisfile.dll) to decode the file successfully,
however the order of the channel interleaving is different to the original wave

Anyone else have thoughts on this? I'd like to get this added before the
1.3.x release. Especially helpful would be research into what current
tools actually do.
