similar to: libao - libsndfile plugin

I have a test program that loads an AIFF or WAV file with libsndfile and plays then using libao. After running around in circles for a while, I found and fixed the problem, but I'm still confused as to why the solution works. Would someone please explain this to me so I don't trip over this again later in my project? I used sf_open_fd() to get a SNDFILE* pointer and an AF_INFO

I managed to get around it. I used the stream functions and provided my own callbacks for reading and writing. What's strange is that what I've done is just copied the contents of read/write/seek/tell/eof callbacks from the sources to my application and it works just fine, no glitches. When I use the build-in implementation, it just crashes without any reason. It's not a problem to

So some research and experimentation I think I found the problem, but I'm not sure how to go about fixing it. If I import one of the wav files into Audacity then export them as "16 bit PCM" then they encode to flac and play fine. The files bitrates are currently at 24. If I export them from audacity as a 24 or 32 (anything higher than 16), flac fails on me. With a bitrate of 24, the

Hi Jean-Marc and others, I put Speex support in Sweep (a sound editor) yesterday, and had some fun with it :) I'd like to get some feedback before releasing it publically. I'm not really used to speech codecs (I work more with music) but I've been quite impressed at the file size and quality (especially when you hear what I did with some of the sample files ;) I didn't have any

I can now load and play AIFF, WAV, and OGG files using libsndfile and libao. Now I'm moving on to loading and playing files embedded in an IFF file. This is presenting a problem. Playing an AIFF embedded in an IFF works fine. Playing an OGG embedded in the same IFF fails. Specifically, it appears that sf_open_fd() can't figure out what it's being told to load. Except for

Hi, sndfile-convert already converts from all these formats to FLAC, but the flac tool itself has more flac-specific options. Is it possible to use sndfile-convert to provide the input data? In any case Erik is maintaining both libsndfile and libflac, and it's unlikely he'd want to duplicate the code. If anything it'd make more sense to remove code for reading other formats from the

Xiph.Org announces the release of libao-1.0.0, libvorbis-1.3.1 and vorbis-tools-1.4.0. This is a coordinated update of the audio libraries and tools to deploy improved surround-sound support across the libraries and toolchain. libao improvements: - AO returned to active development - Added surround channel mapping API and capability - Updated all drivers on modern installs - New config file

Hi there. Sorry I may be a little off topics with this mail but I have already written to the official libao maintainer (volsung@xiph.org) and he is the one who suggest me to write here. As I did not see any more suitable mailing list @xiph.org here I am. My point is that I have recently written a win32 driver for the libao and I would be glad to see this contribution include to the official

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

Hello, I built the entire Vorbis kit on my PowerMac G4 running OSX 10.4.6. I'm having problems however doing anything with the libao package. Any time I try to use the library to link it errors out with the following message: /usr/bin/ld: Undefined symbols: _dlsym_auto_underscore collect2: ld returned 1 exit status If I try to run the ogg123 application I get this:

Hi All, For my new file (and thus mp3) server I've decided to switch completely to Ogg Vorbis. This means having to reencode ~30GB worth of 128Kb MP3's, but i figured that it would all be worth the effort. So I downloaded the sources for libogg, libvorbis and vorbis-tools and fired up my trusty old compiler. libogg and libvorbis built and installed like a charm. Not so for

In January I submitted a new "raw" output driver for libao that lets you write the audio samples directly to a file without any headers or anything else. It never got committed. Is it too late in the beta cycle to add it? I've been contacted by an author of a CD recording application whose problem could be solved by the inclusion of the raw driver. I need to make a change to the

I installed fink and now I have the /sw/lib, however that didn't fix my problem. I went as far as to take out the - Ddlsym=dlsym_auto_underscore out of the configuration files. Now however the libao package won't build at all and yips about this: [ukiel:/MP3/OGG/libao-0.8.6] wind% make Making all in src Making all in plugins Making all in oss make[3]: Nothing to be done for

Hello Vorbis Developers. I'm in the proccess of writing an OggVorbis audio player using libao and libvorbisfile. I've greatly appreciated the simplicity of the API and good documentation with the souce of the libraries. I've descided that I really want a mixer on my player, and I'm unsure how to best go about it. LibAO (unless I'm absolutely blind) doesn't
