similar to: A C# port of Opus is now stable

I am pleased to announce that functional Java ports of both the Opus encoder and decoder are now available, with code derived from the existing C# implementation. As of now it should be considered an "experimental" release, pending some cleanup of the API functions, documentation, and more extensive parity verification. There is also at least 1 known issue which causes minor noise in the

Peter S. - I have a working Opus implementation in C# that I am currently porting to Java. With just a few days' work it should be functional both for encoding and decoding (The main hurdle is just to remove unsigned data types which Java doesn't support). Perhaps we could help each other out? This is my code base: https://github.com/lostromb/concentus/tree/java-staging -Logan

Hi Chandrakala, Logan, Can you confirm that the attached patch fixes the overflow problem? Koen, can you confirm the fix makes sense?

Hi, Can anyone let me know if this is a bug?

Sorry, long holiday weekend in America. I can say with pretty high certainty that there is an overflow occurring and it is flipping smooth_coef_Q16 to be negative when it probably shouldn't be. I had originally thought it was only an issue where it was overflowing the 15th bit but not the 16th, which might still preserve the intended value for operations that ignore the sign bit (in cases

Yes, yes, I can reproduce it now, but only on platforms that define a 16-bit int by default (SA_Q15 is an opus_int rather than opus_int32). What system are you compiling this for?

Just for fun, I tried to reproduce such an overflow. I turned on all debug macros, assertions, and checked arithmetic and then encoded 2 hours of mixed speech/audio with these parameters: Sample rate = 48000 Channels = 1 Application = OPUS_APPLICATION_AUDIO Bitrate = 24 KB/s Force Mode = MODE_SILK_ONLY Signal Type = OPUS_SIGNAL_AUTO Complexity = 10 Frame size = 480 samples (10ms) No errors came

In the C# version of this code, these two copy regions are stored in separate arrays entirely. I agree that there should be no normal way to have the memcpy

Akash- As far as I'm aware, you've got about 2 options: - If you're on a desktop Java runtime you should be able to use JNI bindings to call the native Opus lib. "jopus" on GitHub appears to provide some you can start with. There's probably others. This would be the lowest-cost solution, it's just not very portable. - I have authored a pure C# port of Opus a few

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

Xapians! Anyone know when Xapian bindings for C# will be ready? Thanks, Kevin -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.tartarus.org/pipermail/xapian-discuss/attachments/20060105/257652e0/attachment.htm

I need to write a C# program to create and display Cusum chart from any of the packages, spc, qcc or strucchange. Issues: 1-The data resides in a MS SQL Database. The C# program will handle obtaining the data for the requisite types of samples. Assistance needed on: 1-How can I call the cusum capabilities of any of the above packages and pass the data to the cusum function and plot? 2-How

You could compile Speex as a DLL (see libspeex_dynamic.dsp) and use PInvoke. http://en.wikipedia.org/wiki/PInvoke Note that Speex will still be executing as unmanaged code and your program will have the added dependency of the native Speex DLL. It appears that someone created a "Speex.NET" based on JSpeex, but I didn't find any useful info on it. You may want to search for this

Do anyone has an idea about an open source SIP API written in C# that can communicate with Asterisk, to call out? Regards, Sanjay.

Before I start reinventing the wheel, has anything been done or is there any work ongoing to provide a P/Invoke based interface to parts or all of libFLAC or even a native port of libFLAC to C#/.NET?

Hi FLAC dev's list, I'm looking for a library for the C# language (Microsoft .Net Framework 2.0or higher) to play FLAC files and/or maybe do some other things like getting the file duration, file properties, ... of FLAC files. The library must preferably be free (open source is not required, but is always nice). I hope somebody can help me with this! thx Harry -------------- next part

is wrapping c++ any easier? because there is libFLAC++ otherwise, if you only need a certain subset of what FLAC does it might be easier to write a smaller C interface + wrapper implementation, then import that in c#.

Hi, I know that the general subject "calling R from C" has been discused but I have been reading the manuals and also scouting the lists and I can not seam to find a working solution for my problem. I want to call a R script ( let's call it "test.r" ) from within C# code. After reading about this topic I am trying to do this : System.Diagnostics.Process proc = new

Hi, Can anyone tell me where I can get sample C# code to call the native (win32) dll vorbisfile.dll to decode a vorbis Stream? I want the native performance of this methodology, however Ive tried porting the invocation code to C# and keep getting null reference errors when Calling ov_open_callback.
