What does it mean to compile Speex? what do we get when we do make on the source? i just don't seem to get it :$ thanks! Jonny -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/speex-dev/attachments/20061123/f2aaf86a/attachment.htm

Hello, what is the look ahead for? and what does it do with your data? Can anyone please explain to me how the look-ahead thing works? i cant find information on this :( what happens if i don't use it? can you please help me? thanks! PS: i thinks the codec is a great initiative, i have to make a project for school, and we chose speex :) We are developping a small app to just play some

Hello, im using speex library on my vo ip project, but some times, after it works ok, it begins to play noises (like voice hits) decoding the packets of one source (the others sound ok). I finally found that reseting SpeexBits and decoder state it solves. If i cant avoid this problem, i wish to solve when it occours, but ?how to detect this? Please, if anyone has experiment this issue i

Hi all Sorry if this is a dumb question: does the input_frame passed to speex_encode_int *have* to be frame_size samples long? e.g., If I only have 100 samples left to encode (which is less than the frame_size of 160 samples), can I just use an array that contains 100 samples, or do I need to create an array containing the 100 "real" samples plus 60 null samples at the end?

.Call("compute_values_cpp") Also, if you were passing arguments to the C++ function you would need to declare the function differently.

You might not be doing anything wrong. Speex is stateful and can get into a bad state sometimes. It's happened to me too, but not recently. And I've seen such bugs reported on this list and fixed. I suggest several approaches to solving the problem: 1) Try compiling Speex without compiler optimizations and see if the problem still occurs. Most likely it will, but this is an

What are you expecting exactly here? That I explain what's a Hertz and what's a

Hi, I have written a small C++ function and compile it. However in R I can't see the function I have defined in C++. I have read some web-pages about Rcpp and C++ but it is a bit confusion for me. Anyway, This is the C++-code: #include <Rcpp.h> using namespace Rcpp; // [[Rcpp::export]] List compute_values_cpp(int totalPoints = 1e5, double angle_increment = 0.01, int radius =

Following a post on vqf.com forum, I found out that some company called Adapted Wave Technology is ready to release its audio codec based on wavelets. They say that this wavelet-based codec is superior to MDCT codecs by 30-50%. One sentence caught my attention: "Adapted Wave Technologies holds exclusive patent rights for applying wavelet packets to audio applications." - sounds like a

I am trying to detect a positively increasing trend in a time series data, to which when I apply the rolling mean it almost turns into a step wave function. The sharp rise in slope of rolling mean is an indication of positive trend, thus the rolling mean becomes like a step wave function. Is there a way or package to automatically detect the sharp increase in slope? -P [[alternative HTML

At the risk of throwing more fuel on the fire, I found the following document on the Microsoft website. It appears to be the file format counterpart to the API documentation presented by Chris Wolf. I'm not familiar with the WAVE format, so I'll let you guys interpret it (or tell me it is irrelevant): http://www.microsoft.com/HWDEV/audio/multichaud.htm [As an aside: Why does Microsoft

Hello, I have an p2p voice chat application using WAVE PCM (winmm). Now i am trying to add opus encoding to it to send it over the TCP/IP and then decoding it back to play - but without success (without opus it works ok) Here is an example of my code. I get message from input device then encode with opus then decode it back to output wave header and play. Doing it i hear only noise in my

Is there a way to have asterisk setup in ALSA mode (which is working) but also be able to "play file.wav" and hear that also. CONSOLE/dsp is working. If I stop asterisk and "play file.wav" that works. But if asterisk is running I cannot also play a file.wav I am not actually doing them at the same time. Just a couple files here and there to play. But as is I have to stop

Hi, I'm recording wave files but I cant get Asterisk to play them, only if they are in 8000 Hz. What is the maximum sample rate Asterisk can handle? I have been using 16-bit 44.1, 22050 and finally 8000 kHz. Many thanks, Christian

Hello On a Sipura SPA-841 handset (and also at other end) you hear a sea wave like sound - it gets louder then softer and continually repeats. I don't remember hearing this when using other handsets. But what is this effect? How can I reduce it? Angus

Looking at my shiny new Google Wave account, I was wondering if anyone else on this list is in the beta AND going to Astricon. Astricon seems like it would be a good test of the kind of collaboration GW is trying for. In any case, I'd love to try to do an Astricon wave so let me know if you're interested and we'll get together. I know at least two other people who'll be there
