I still wonder how it is possible that this didn't trigger anything

Hi all, With the patch I mailed earlier today, I found out a few adjustments could be made to the compression level settings.This retuning speeds up the encoding and improves compression, while not changing anything decoding-wise. Currently, compression settings are as follows -5, -l 8 -b 4096 -m -r 5 -A tukey(0.5) -6, -l 8 -b 4096 -m -r 6-A tukey(0.5) -7, -l 8 -b 4096 -m -e -r 6-A

And I am willing to looking at FLAC and spent my time to fix compiler warnings to make it more portable and

Hello. I create FLAC file decoding, processing and playing program and have the following question : how to convert FLAC 16 bit file data to 32 bit float buffer for CPU processing? I've already inplemented sound playing and tested it with sine wave - it works without problems; I even made writing into decoding buffer values of sine wave, instead of decoded FLAC file data, and it also works

As we?re talking 1.3.1 release, I?ve been keeping track of a couple of changes that I feel should be included in the changelog and that I might as well share here. The things between brackets are just to refresh memories, I?d leave them out of the actual changelog. * Improved efficiency of 24 bit decoding. (https://git.xiph.org/?p=flac.git;a=commit;h=ea0d5ddadc6902e873983c89f473130b3bb6625f) *

Currently apodization function is hardcoded, see commit <http://git.xiph.org/?p=flac.git;a=commitdiff;h=4e8fe85bceb245dfce07d1956b144e1cb6587c9f> FLAC is locale-dependent so "tukey(0.5)" doesn't work for locales with decimal comma. But "tukey(5e-1)" should be locale-independent so it is possible to re-add 'const char *apodization' member into

Running the basic (--disable-thorough-tests) test suite, I get these failures round-trip test (rt-1-24-111.raw) encode...

By contrast, i386 is fine. (All OpenBSD/4.2.) Could be a generic LP64

Hi all, This patch adds two new apodization functions that I developed. From my own test results (on quite a diverse dataset) they outperform the current best apodizations by 0.05% - 0.1% (depending on the specifics) on compression. Here's a selection of the test results *Apodization functions* ,Compres, Speed partial_tukey(2) tukey(0.5) , 56.50 , 37.2x partial_tukey(3)

In clang is it possible to declare C-language function prototypes for overloaded functions even though it is not C-language legal. It's because I see that GLSL provides something like this, and I'm wondering if clang does too and how to express it either through command line argument or language attributes, etc.? int f(int, int); float f(float, float); int g() { float x = f(1.0f,

I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to get it. Here's what I have: -a new file, lpc_asm.s, which has the assembly routines -changes to cpu.h, cpu.c, and stream_decoder.c to enable them -changes to configure.in to support the new cpu stuff -a preliminary Makefile.am -maybe something else I'm forgetting Now automake complains that configure.in

Yes, that is correct. These functions are used to window the audiodata, but only for the predictor stage. What these new function enable,

There are following functions in bitreader.c: FLAC__bool FLAC__bitreader_read_unary_unsigned(FLAC__BitReader *br, unsigned *val); FLAC__bool FLAC__bitreader_read_rice_signed(FLAC__BitReader *br, int *val, unsigned parameter); FLAC__bool FLAC__bitreader_read_rice_signed_block(FLAC__BitReader *br, int vals[], unsigned nvals, unsigned parameter); * function FLAC__bitreader_read_rice_signed():

Hi, I finally got around to trying to update FLAC for the MAME/MESS project again. There were several issues I was able to fix and will submit patches later, but I hit one roadblock with GCC and clang: src/lib/libflac/libFLAC/stream_encoder.c:1696:43: error: cast from function call of type 'double' to non-matching type 'FLAC__int32' (aka 'int')

Hello, I just tried to compile libFLAC (using Borland C++ Builder 6 on Windows). The compilers yells at me on line 233 of libFLAC/lpc.c *(residual++) = *(data++) - (sum >> lp_quantization); --> data is const and cannot be modified Funny thing is, if data is declared: const FLAC__int32 *data instead of const FLAC__int32 data[] everything is ok. Is this a bug in my compiler, or

Hi, In the last days I've been taking as reference the example found in examples/c/encode/file/main.c. With it I've been able to encode a 2ch, 16 bps, 44100 sample rate input WAV file to a FLAC file. Now I've been trying to modify this example to encode a 2ch, 24 bps, 96000 sample rate WAV file. I have to say I'm a bit lost on how I should read the input file in this case, and

Hi all, I'm attempting to encode raw audio data using libFLAC++. My audio data is 16 bit, mono, 16000Hz. I set all the appropriate parameters on the encoder and then call init(). Everything appears to be ok. I don't know how to properly convert from char *data to the FLAC__int32 *[] requested by the process function. I think this is where my problem is. If I call process() like this:
