Hi Jean-Marc, As I told you, bank is a reserved keyword in Analog Devices compiler for Blackfin architecture. So we need to change the variables named bank to something else. Here's a patch that changes bank to bnk in the 3 concerned files. (Hope the format is OK) About my previous problems with the Blackfin: -> strange block repetition that could be cancelled by the AEC I was busy

Hello, Filterbank.c does not compile on visual studio because of the declaration of : int id1; int id2; in the filterbank_new() procedure (line 45) id1 and id2 must be compiled in the begin of the procedure... Ouss

Hello vorbis developer! I'm not very experienced in informatics, cause i'm only an audio engineer and sorry for my broken english but i have an idea... After the filterbank the maximum aplitude in each band decides about the nessesary bits, then the psychoacoustic model decides how much of the signal can be truncated without hearable noise. What do you think about quantising the

Hi again, I have improved precision of my codec (on the encoder and decoder).I have also improved the -h1 quality setting.-Source code and binaries at http://nhwcodec.blogspot.com/-. I am still trying to improve precision of my codec, with keeping my low-complexity (fast) approach. I do not totally use the reference (and impressive) block prediction with different modes + residual coding scheme,

Hi all, I build successfully with speex-1.2rc2. And with speexdsp 1.2rc3, I build with i386, X86_64, armv7 and armv7s all passed. But when I build for ARM64 (for iPhone 6), it failed with: /Applications/Xcode.app/Contents/Developer/usr/bin/make all-recursive Making all in libspeexdsp CC preprocess.lo CC jitter.lo CC mdf.lo CC fftwrap.lo CC

Hello to everyone! During building speex library for Symbian OS I encountered some problems. All thess problems can be solved by modifying the speex sources. I don't have access to SVN repository of speex, so I will just describe the changes to be done: 1) mmp file in symbian derictory misses windows.c sources. You need to add this string into speex.mmp: SOURCES windows.c 2) Symbian OS

Hi, VS2005 project (libspeex.vcproj) seems to be missing some files, most notably filterbank.c. Also some .h files but that doesn't really matter. Gregg

Hi Jean-Marc, I tried to add VERY_SMALL at the input of the encoder, but that did not change much. Here's a list of source code locations where denormals appear for the first time as calculation results. This list is based on a 4 minutes recording of ambient sound that is passed to speexenc 1.2rc1 with the command line --narrowband --denoise --agc --abr 15000

Hello, I am thinking about plugging in Discrete Wavelet Transform as described in Vorbis I spec: 1.1.2. Classification Vorbis I is a forward-adaptive monolithic transform CODEC based on the Modified Discrete Cosine Transform. The codec is structured to allow addition of a hybrid wavelet filterbank in Vorbis II to offer better transient response and reproduction using a transform better suited to

This patch updates the symbian build files to latest svn trunk, and also adds a new makefile for speexdsp. Signed-off-by: Alfred E.

I've filed a bug for aarch64 https://github.com/xiph/speexdsp/issues/7 and provided the port in a fork with a pull request. We need someone to review/merge in the pull request? It provides the source code, but my testing was under Android builds, so there would be some configure changes needed to build it stand alone.

hi Jean-Marc, I just updated from svn and it looks like there are some errors in the speex.mmp file. the filters.c is duplicated, and the fft/kiss.c files are still missing.. /alfred Jean-Marc Valin wrote: > Applied in svn.

Hello, Definitely not any (constructive) comments on the NHW Image codec? According to my tests, it can compare good with reference codecs like x264 intra and WebP. Yes, the codec is still experimental and is optimized for visual (subjective) evaluation, not PSNR.Its main feature is again that it would have a little more neatness/sharpness and a little less precision (residual coding is applied
