Hi All, I need some clarifications regarding the mismatch I found in the code and the specification. (a) In the specification, the bark(x) equation is given as: bark(x) = 13.1 atan(.00074x) + 2.24 atan(.0000000158(x^2)) + .0001x whereas in the code it is given as: #define toBARK(n) (13.1f*atan(.00074f*(n))+2.24f*atan((n)*(n)*1.85e-8f)+1e-4f*(n)) Which one of these is the proper one ? (b)

Could someone point me to the BARK/MEL tables that these macros (from vorbis/scales.h) are trying to approximate? #define toBARK(f) (13.1*atan(.00074*(f))+2.24*atan((f)*(f)*1.85e-8)+1e-4*(f)) #define fromBARK(z) (102.*(z)-2.*pow(z,2.)+.4*pow(z,3)+pow(1.46,z)-1.) #define toMEL(f) (log(1.+(f)*.001)*1442.695) #define fromMEL(m) (1000.*exp((m)/1442.695)-1000.) I was wondering if I could come

Hi, In the course of some work which I describe below, I have found a very significant difference between the BARK function described in the Vorbis specification and its implementation in libvorbis. In the specificationhttp://xiph.org/vorbis/doc/Vorbis_I_spec.pdf bark(x) = 13.1arctan(.00074x) + 2.24arctan(.0000000185x**2 + .0001x) In the libvorbis code

Hello list I think I really finally found a way to crossbuild a binary for ARM using Clang/llvm. This message would be a documentation for someone who may concern for the same issue with me. - Target : TOSHIBA AC100 / Ubuntu 12.04 (https://wiki.ubuntu.com/ARM/** TEGRA/AC100 <https://wiki.ubuntu.com/ARM/TEGRA/AC100>) - Host : i386 Desktop PC / Ubuntu 12.04 - Toolchain on host : sudo

Hi Journeyer First, thank you so much for your updates on your experiments. I am currently following your steps but have found myself stuck with the following error: /usr/lib/gcc/arm-linux-gnueabi/4.6/../../../../arm-linux-gnueabi/bin/ld: this linker was not configured to use sysroots clang: error: linker command failed with exit code 1 (use -v to see invocation) I used the command string you

Hi, It is better to replace this line in function filterbank_new: max_mel = toBARK(EXTRACT16(MULT16_16_Q15(QCONST16(.5f,15),sampling))); to max_mel = toBARK(EXTRACT16(sampling/2)); It gives the same but it seems to be faster and avoids overflow on 44100 kHz that prevents denoiser to process 44100 streams. (Yes I know that Speex should not pack 44100 streams but it does now and I use it). Best

Hello! Some minor bugfixes... source: psy.c function: _vp_psy_init 1. '-' or '+' in this line? maxoc=toOC((n*.5f - .25f)*rate/n)*(1<<(p->shiftoc+1))+.5f; maxoc=toOC((n*.5f + .25f)*rate/n)*(1<<(p->shiftoc+1))+.5f; 2. I know: sizeof(float *) and sizeof(float) are 4 bytes long, but... old lines: p->noisemedian=_ogg_malloc(n*sizeof(float *));

Dear Moderator, I downloaded Vorbis 1.2.0 code from your website and I tried to build a project in Visual studio 2008, as the earlier version was created in VC 6 version it has been modified here. In the solution I have 6 projects vorbis_dynamic, vorbis_static, vorbisenc_dynamic, vorbisenc_static, vorbisfile_dynamic, vorbisfile_static. When I tried to built the project, it shows error that it

Hello, I am trying to get hold of the sources for the ogg vorbis DirectShow filter. I have checked out trunk\oggds, but the solution refers to projects under OggSDK, viz: "OggSDK\ogg\win32\ogg_dynamic.vcproj" "OggSDK\vorbis\win32\vorbis_dynamic.vcproj" "OggSDK\vorbis\win32\vorbisenc_dynamic.vcproj" ....which do not appear to be in subversion. The

Hi, [ I think I put the most important contributors to the DebugInfo stuff in Cc:. Is there anyone else that I am missing? ] Just a short notice that I am currently working on making llvm-dwarfdump more developer friendly. There are quite a few features in Darwin’s dwarfdump that we find quite useful and that we would like to contribute to llvm-dwarfdump. I have started by augmenting the

Hello group, I'm having a very hard time rsyncing efficiently a MySQL database which contains very large binary blobs. (Actually, it's the database of Mantis bug tracker [http://www.mantisbt.org/], with file attachments stored directly in the table rows. I know it's a bad idea from many other reasons, but let's say it was given to me as such.) First, I was dumping the

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

Since the goal is to start llvm-tapi more or less from scratch, I feel the best approach initially is to focus on the structure as a key point of feedback in initial reviews. Once the foundations are set, integrating Mach-O TAPI in parallel with the ELF implementation should be relatively straightforward. The features outside of stubbing aren't as appealing for ELF, so I probably won't be

Hi again! I have some other suggestions/modifications. 1. Bitrate scaling by frequency in vorbis_encode_init: bpch=(long)((float)nominal_bitrate/(float)channels*44100.0f/(float)rate); With this modification, if we use -b128 at 22khz files, the OGG file will be 128kbit/s, not 64kbit/s ... 2. Probable quality bug: I tested some floating point constants (recalculated them (see below) and encoded

Hi, A lot of the problems with openssh portability so far appear to be with the login record functionality, i.e. lastlog support, and variations on handling utmp vs. utmpx etc. Looking at for-profit SSH 1.2.27, login.c is rather embarassing spaghetti code, so laden with '#ifdef's it's almost impossible to read. OpenSSH's code isn't anything like that, but then it doesn't

Hi, I have been trying to compile win, and to be honest, I am not real good at compiling, so when there is an error, I am left to hunting postings to try to find help. I lucked out and found a message thread with the exact same problem that I have, however, there was no response as to how to get around this. Any suggestions please would be greatly appreciated. I am running Red Hat Linux 7.0. Here

Hi, I have an application that I use that only worked on Wine-20001222 and a few earlier versions. I accidentally deleted my copy and when I tried to download it again, it was no longer posted on any of the sites that I know that carry the source files. If somebody could send me another link to a site for downloading or even email the program to me would be great. Thanks, Ken -- Kenton

Hi, One of the main things I use Wine for is to run a Computer Based Training Player (cbtplayer, info found at www.smartforce.com). It used to work perfect on 20001222 and back several version from that. Since the 20010112 release, it has failed. I reload the 20001222 and am back in business. I posted the zipped debug output for download if anybody that can read this (most of it looks Chinese

I was wondering why my CD ripping was producing short files from some tracks. A superficial examination of the code shows this piece of code in vorbis-tools/oggenc/encode.c: Line 120: /* Main encode loop - continue until end of file */ while(!eos) { [...] /* While we can get enough data from the library to analyse, one
