Is there any way to access only the narrowband portion of a wideband stream? I'd like to be able to encode the audio only once, but allow members in a conference to have some rough selection of bandwidth, and allow them to move to a lower-bitrate stream if there is a need to do so.

Hi, I'm Ossama Khayat, an Arab .Net Framework developer. I'm interested in building an API or COM component, of the speex codec, that is suitable for use in a Windows Forms application. This will be used in an Open Source project that will hopefully be hosted in Source Forge one done. I tried downloading the source code and compiling it but really couldn't do much with it, especially

The Speex ACM codec has been released as version 1.0.1.1. Enjoy! Here is a list of changes: * A setup application has been added to the release. Just click SETUP.EXE and follow the instructions. * The crash under Windows 95/98/ME was fixed. * A reported crash in VirtualDub, CDEx and possibly other applications was fixed * The codec's Format Tag was changed to an official Microsoft

Apologies if this is a bit of a commercial post (I've not been lurking long), but you might like to know that the world's most listened-to online radio station has just launched an Ogg stream.

Thanks! > /Pontus This is (sort of) done in the decoder with the optional perceptual filtering. Speex tries to shape the noise so that it sounds more pleasant, I believe. To really use perceptual coding, one would require fine granular control over quantization

Hmm, the call to speex_encode_stereo() takes the frame size as an an argument - and this call generates bits ;) So possibly my bitrate table shows wrong values in the stereo cases. Hmm...

the stack variable bytes_written is never initialized.

Hey, can we make the pointers to the encoder and decoder state variables somewhat more strongly typed? ;) I made a mistake where I basically wrote speex_decode(&st, ... instead of speex_decode(st, ... That is why my decoder blew up all the time. The compiler wouldn't complain. I suspected a corrupt speex bitstream, a corrupted stack frame, etc... So much time wasted because of an

If you want to use the Speex ACM codec in Netmeeting, you need to register the codec with Netmeeting. Microsoft offers an API to accomplish this task. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/netmeet/nm3 codec_1xk3.asp The function is called AddACMFormat in the IInstallAudioCodecs COM interface. It takes a fully initialized WAVEFORMATEX structure as well as an extra

Hello, just a brief report on where I am going with that Windows CE ACM Speex codec. * I managed to compile the GSM610 sample codec by Visual C++ Embedded for the ARM processor. This is set up as a DLL project in the IDE. Replacing the implementation with the existing Win32 code should be straightforward now. * I wrote an install/setup procedure for the codec (works fine) * I built a
