similar to: Speex in VB .NET

Hi there, I have searched what seems like everywhere and was unable to find a .NET wrapper so that I can use speex in VB. I did find a speex.NET.dll but this didn't seem to work on what I needed. I therefore decided I could just use DllImport within VB .NET and create my own unmanaged links to libspeex.dll. With the help of this partial c# code

hi all What is the best version to use denoise and echo cancellation encode and decode with vb.net i tried exes with command line orguments i am getting an error at StandardInput.BaseStream.WriteByte where can i get implimentation vb.net or c# sample Please help me From Venkata ramana India -------------- next part -------------- An HTML attachment was scrubbed...

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

Why don't you just try it? From what others have been reporting, it shouldn't take you long to get it running. You can use speexenc and speexdec for testing.

vincent, it should work out of the box. real time speex should work on the iphone as it has a really fast arm cpu (and speex works in realtime on even the 201mhz arm cpus). while compiling, remember to define the fixed-support support and you are all set. narrow band (8khz) and 8kbps bitrate will work very well. while you are at it, pse send the xcode project file to include in the tarball. -

Hello Ashhar, thanks for your reply, but i'm a bit surprised. 1- Does it mean that it is possible to make a Real Time Encoding/Decoding with SPEEX on iPhone ? 2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and what kind of CPU load do they measure for that ?

thanks for your reply, could you explain why 44.1kHz is *not* recommended with SPEEX ?

ok, interesting ! Do you know how much CPU it takes for a real time encoding/decoding ? it's more around 20% or 80% instead ? Do you know if it works for 44100 Hz / 32kbps / Quality =8 ? thanks again.

Did I ever mention that 44.1kHz is *not* recommended. Usually, 16 kHz is best, although 32 kHz can be good in *some* cases. In any case, you'll need to listen

hello, i 've already used SPEEX in a protoype of voip application (on VC 6) and i must says that it works well, the sound is good, and the object works well with multi-instances. But now i'm wondering if it's possible to port the SPEEX encoder (and decoder process) on iPhone ? Does someone tried to do that ? Do you think it is possible or completly over the capabilities of the ARM

Hello, i want to use speex out of visual basic. So i have written a few wrapper functions in VC++ (v6) wich i can call from VB (v6). But i have problems with the encode and decode functions. Encode wrapper Function: I want to copy the value of an single array in VB to a float array in C which can be encoded. And the output of the encoder have to be unsigned char because in VB its an byte

Hi everybody, I am fresh for speex and vs.net c#,and I want to use speex in a existed project written by c# language,does anybody done this before?because I do not know how to use c in c#,I worked under linux environment for years,never touched vc.net.Maybe compile the source code into dll file and use them?I heard about the wrapper,what does this mean, Regards Chris -------------- next part

Has anyone written a wrapper to use with .NET for the speex Win32 library? I had started to work on it but thought best to ask first. :) Thanks, Jessica <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word

vincent, someone in our team did compile it on iphone. he didn'y any particular problems. the arm specific optimizations are not necessary given iphone's fast cpu. just add all the speex sources to xcode's project pane and compile it. - farhan On 11/7/08, Vincent Burel <vincent.burel at vb-audio.com> wrote: > hello, > > i 've already used SPEEX in a protoype of voip

A .NET API might be a useful thing. The way I see it, the only way to do it would

Hi! I guess you heard this question before, but does a .NET-port of Speex exists? I tried to port the JSpeex, but had some major problems with encoding and decoding. I can hear myself :), but there is way too much noise (and loud too, not very pleasant for the ears). I believed this was an error that got into the port I did, so I decided to write a "wrapper" around the original
