1.21 vs 1.3 encoding speed
Are you sure they didn't change the default encoding level ?
I would include some example timings to give a better idea of what "significantly slower" is
Wonder if you see same for 44/16 files?

Please cc: the results from dev list back here though
I would run some tests on a diff platform but don't have access to my PC for a few weeks
Would also be interesting to see what decoding stats you get

1.21 vs 1.3 encoding speed
Hello,
I'm on a Mac and I'm noticing that encoding via the flac command line is
significantly slower with version 1.3.0 than 1.2.1. I'm encoding a 24/96
file to flac, both from wav and aiff and both formats are showing the same
speed decrease when using 1.3.0.
To give an idea of the speed decrease, encoding at flac level 8:
24/96 wav file
1.21: 61.05 seconds. ratio=0.690
1.3: 222.48

1.21 vs 1.3 encoding speed
a. Intel 2.8 Ghz Core I7 (dual core, I7-4558U) in late 2013 Macbook Pro
with Retina Display
b. I compiled it the same way I compiled 1.2.1:
./configure -enable-static -disable-shared CFLAGS=" -isysroot
/Developer/SDKs/MacOSX10.6.sdk -mmacosx-version-min=10.6"
make
Am i doing something wrong?
Thanks,

I will post to the dev list, sorry about that.
To give an idea, though, at flac level 8:
24/96 wav file
1.21: 61.05 seconds. ratio=0.690
1.3: 222.48 seconds. ratio=0.690
smaller 16/44.1 wav file
1.21: 14.28 seconds. ratio=0.487
1.3: 51.21 seconds. ratio=0.487

flac-dev Digest, Vol 116, Issue 19
Why are you using such an old SDK? Your Macbook came with at least Mountain
Lion, right? I have a Retina Macbook mid 2012, and it came with ML...

Is it -O3 or -funroll-loops that you have a problem with? Or both?
What would you prefer to see as the default optimisation level?
I'm sure there is a solution to this. Lets find

error in files after removing padding
ERROR while decoding data
state = FLAC__STREAM_DECODER_END_OF_STREAM
It's happening with every file that I've tried now, using both 1.2.1 and
1.3.0.
If a file has artwork and I remove padding, I get the above error when
verifying or decompressing. If no artwork and I remove padding, the file
verifies and decompresses with no issues.

FLAC 1.2.1 on OS X 10.4.11
hi,
according to the FAQ flac supports multichannel formats. i had no
luck with 1.1.4 though ( "Untitled.aif: ERROR: unsupported number
channels 8 for AIFF" ), i guess that feature was added in 1.2?
unfortunately, the binary for 1.2 does not run on OS X 10.4 (says
libiconv is too old). i removed libiconv and reinstalled that from
source, but then flac 1.2.1 just prints

command-line: AIFF writer advice
The patch I submitted only reads AIFF files. I'm about to start the patch to
write AIFF files.
To do so, we need a command-line option to specify AIFF. My inclination is to
add an option:
-ff { raw | wav | aif }
In some sense, "-ff" is silly since it probably stands for "format format".
Still, I think it's better than just "-f", since the first

Encoding the wrong Endian and AIFF
I know this is probably blindingly obvious, but
I can't find it anywhere. Is there a way to tell the
Vorbis codec what endian your samples are or do I
have to do my own byte reversal.
AIFF is Be's 'standard' audio file format, and its encoded
big endian, not little endian even on Intel boxes.
I know for decoding ov_read has an endian option,
but I can't see an equaivalent for

96k/24-bit BWF encoding
Hi,
I am attempting to use flac to encode 96k/24-bit broadcast wav (BWF)
files. BWFs are wav files with some extra meta-data chunks, and is the
favoured archival format for many institutions around the world.
These files are encoded successfully by flac, however the resulting
flac file is not playable on all flac players - it plays successfully
in foobar2000 but is silent in winamp, and when

FLAC 1.2.1 on OS X 10.4.11
yes that is what i did. got the "requires version 7.0.0 or later, but
libiconv.2.dylib provides version XYZ" (forgot which version i had
before). removed libiconv, downloaded compiled and installed the new
one (libiconv-1.13.1), then i just get
$ flac
Bus error
i reinstalled flac 1.1.4, still runs fine (but doesn't support
multichannel).
cheers, -sciss-

FLAC QUESTION
Hello, in fact :
this error(FLAC__STREAM_ENCODER_VERIFY_MISMATCH_IN_AUDIO_DAT) occurs when
the sample size is bigger than the exepected size in the encoder.
Now, can someone tell me how to model the signal, for example :
*using a Fixed linear predictor for the input signal ? *

flac error with some aiff files?
flac.exe is choking on some aiff files as input with the following:
"ERROR: SSND chunk size inconsistent with sample frame count"
According to Daren on the dBpoweramp forum "The flac.exe program ignores
the amount of data bytes quoted in the SSND chunk and tries to read to
the end of the file, which would be fine if the SSND data was the last
data in the file. The problem is

flac alpha with RIFF/AIFF metadata support
just recently I have finished implementing support for saving
non-audio chunks in RIFF WAVE and AIFF with the FLAC file in
application metadata blocks, and restoring them when decoding.
you can read about more about it here:
http://www.hydrogenaudio.org/forums/index.php?showtopic=56968
the zip file there has windows binaries; CVS HEAD has everything
checked in if you need a different platform.

--keep-foreign-metadata question
Not sure if this belongs here or in flac-dev.
I am subscribed to both, so flop it over if fits
better over there.
Looking at the Changelog for FLAC 1.2.1
(17-Sep-2007), it says:
"With the new --keep-foreign-metadata in
flac, non-audio RIFF and AIFF chunks can
be stored in FLAC files and recreated when
decoding."
Where can I find more detail on what is a
