I've checked my interpretation against "flac -a" and it seems to
read 17 bits for each warmup sample. Here is its output:
frame=168
blocksize=4608

Getting subframe type=verbatim on 16 bit files
looks fine, I would suspect how the PCM sample are formatted
and sent to process(), could you show that part of the code?

Getting subframe type=verbatim on 16 bit files
I'm using libFLACC++ and libFLAC and I think that I'm using the calls in the
typical order (see code below). But every monoe or stereo file that I send
thru I get files that are the same sze as the orginal wave files.
Doing a flac -a on the flac files I see that I get:
frame=9 blocksize=4608 sample_rate=8000 channels=1
channel_assignment=INDEPENDENT
subframe=0

Getting subframe type=verbatim on 16 bit files
Here's how I set up the data for processing:
// For moving data into 32 bit shape
uint8_t *buffer8 = NULL;
uint16_t *buffer16 = NULL;
uint32_t *buffer32 = NULL;
unsigned sample32;
unsigned sample, channel;
uint32_t bitsPerSample = this->get_bits_per_sample();
numFrames = inData.GetSize();

Altivec, automake
Here's what I listed in that email. Merging doesn't appear to be necessary. If
you have any build problems, let me know.
Note that my detection code is Darwin-specific. It's a BSD call (sysctl()), so
a change to the platform-detection macros should enable it to work on other
BSDs. However, I don't know what that would be, and I couldn't determine any
safe way to do the check

two small-ish optimizations (death by a thousand cuts)
This lpc_restore_order was partially inspired by Miroslav's affd, though
my (not very great) ARM asm version resembled this, as well.
The other two reduce CPU array indexing overhead in loops a little.
Additionally, a request for help:
My not very optimized lpc_restore_signal is at the below URL, I
couldn't get the ldm* instructions to work as advertised, even though

Voila, this was the source of all my frustration, sync problems and
who knows what.
My decoder now works correctly for files encoded with the default

dbench strange results
Hi
I'm building new samba server (on Debian 6.0, software RAID10 2TB, Xeon
CPU). Generally everything is working fine, so I have decided to run
some stress tests. My choice was dbench. Old server is Debian 4.0 (samba
3.0.24, Athlon 3000+, one ATA 160GB disk). So run
dbench 16
on both old and new server
The results are strange
old serwer: about 300MB/sek (dbench 3.0)

I think it would be interesting to know how common are such streams. I
patched flac to print a warning on decoding or testing

investigate & troubleshoot speed bottleneck(s) - how?
hi guys/gals
I realize that this question must have been asked before, I
sroogled and found some posts on the web on how to
tweak/tune gluster, however..
What I hope is that some experts and/or devel could write a
bit more, maybe compose a doc on - How to investigate and
trouble gluster's speed-performance bottleneck.
Why I think such a thorough guide would be important? Well..
I guess

Rice coding parameter
Hi,
I asked a few questions about the flac format a couple of weeks ago. One more (if you don't mind) about the Rice coding. The Rice parameter "k" can't be zero (unless I'm mistaken), yet the FLAC spec says the Rice parameter can range from 0 to 15.
I guessed, and tried adding one before using the parameter (i.e. assuming the range was really 1 to 16), and that didn't

Well, configure is obfuscating, but that's not really the
