Hello, I have written a libsndfile (http://www.mega-nerd.com/libsndfile/) file output plugin for libao. For the moment I haven't done any changes to the core of libao. However some changes could make this more useful. Before I embark on anything like this I'd like to have your opinion on a few things. --- First, what...

I was actually starting my small ?project? with libsndfile, but it was done in a way that I didn't agree with, and since I only work with FLAC files (mostly 24 bits) I decided to try to go with libflac instead, which seems to let me do things the w...

...39;m using the Linux to MinGW cross compiler toolchain to build windows binaries for one of my libraries. I'm also trying to run the cross-compiled binaries that make up the test suite under wine version 0.9.58 from ubuntu hardy heron. The DLL for my library gets built as: /home/erikd/Bzr/libsndfile-mingw/src/.libs/libsndfile-1.dll and the test suite binaries get built in: /home/erikd/Bzr/libsndfile-mingw/tests If I go into that directory and run the following script: #!/bin/bash dll=libsndfile-1.dll dlldir=/home/erikd/Bzr/libsndfile-mingw/src/.libs if [ ! -f "$d...

In my experience, with the gcc compiler, cross-compiling is highly reliable. If your code runs on one processor, then it will run on all. Linking and such might be an issue, which you will discover immediately when the first person tries to run what you've built on their system. It still would be great to run these tests on all four. Actually, you should be able to test 32-bit

...d interface should be maintained for compatibility with existing software. The new, friendlier interface can simply use a slightly different (member) function name to access the same objects. There's no reason both can't be supported, or even float as well. > Something to match libsndfile's ease of > use. I do not use libsndfile, so I wouldn't make this comparison.

I realize that I'm a couple of years late in saying so, but you're right. I finally took the time to download libsndfile and compile it (for Leopard), and snd...

That can easily break down in all sort of places. For instance, I'm the main author of libsndfile and when Apple first announced Intel based machines I started getting weird bug reports about libsndfile on Intel macs. After I spent a bunch of my very valuable time the idiot reporting the issue finally confessed that he was compiling libsndfile as a universal binary on PPC and then seeing bugs...

And of course you won't waste your time replying outside this mailing list? Is there a libsndfile mailing list? Hm? yet another stupid question, of course.

...ontact them for access to the coverity reporting facilities. The reason I am keen to see Xiph take up this challenge is that when all projects listed on the above page address the issues listed, all of the projects can move to the next rung where more of the Coverity tests are enabled. My project libsndfile is on the same list as libvorbis and libsndfile can't move forward until the libvorbis issues have been fixed. For the record, the Coverity tool found 8 possible issues with libsndfile, 5 of which were false positives, but 3 of which were genuine bugs. Cheers, Erik -- -----------------------...

...Hz isn't directly supported although flac can compress such rate in lax mode. My last question - is there any chance for flac to support w64 files? That would be cool since it would allow to compress >2Gb files. (not sure if flac can compress >2Gb raw files) See http://www.mega-nerd.com/libsndfile/ for reference. Marek

Dear experts, I am trying to use an example I found here: http://svn.xiph.org/trunk/vorbis/examples/encoder_example.c Could you please tell me what float** buffer is needed for (I don't see it used anywhere). Also, could you please tell me what this code is doing: for(i=0;i<bytes/4;i++){ buffer[0][i]=((readbuffer[i*4+1]<<8)|

Hello all, Is anyone here potentially up to the task of adding support for CAF (the CoreAudio Format) into the flac command-line? This would present minimal difficulty under OSX, due to the presence of the CoreAudio API, but the real challenge would be to support CAF on Unix and Windows - everywhere that flac is now available. Although the format is rather unknown, there are some very

Hello, I am currently learning the FLAC C API and had the code working with FLAC__stream_decoder_init_file. However, since I'd need the Unicode filename support, I tried _wfopen_s in combination with FLAC__stream_decoder_init_FILE, however I get a runtime crash as sonn as I call FLAC__stream_decoder_process_until_end_of_stream. The same code (partially taken from the examples) is working
