similar to: how to play multiple speex audio streams simultaneously

Another approach that I have come across is to decode all speex audio streams and add their 16 bit signed PCM values clipping values above 2^15-1 and below -2^15. Is this a reliable appproach?

Hello Vishal, Do not even think of playing each stream in separate thread! :) That's not the way. Yes, you will have to create multiply decoder instances for each audio stream. And you will have to create one playback device. Your application should have one playback thread where you'll iterate over the streams (e.g. data can be stored in stl container) and "mix it by hand".

I am trying to compile speexclient.c. I downloaded all the files to ~/speex- 1.2beta1/include When I call ./compile.sh I get the following errors, speexclient.c: In function 'main': speexclient.c:164: error: 'SPEEX_PREPROCESS_SET_ECHO_STATE' undeclared (first use in this function) speexclient.c:164: error: (Each undeclared identifier is reported only once speexclient.c:164:

Hi All, I would like to communicate speech over a network compressed using speex. However, I do not want to communicate a whole Ogg-formatted file. I am interested in only the speech frames. I invoked: speexenc input-file-name - > raw-speech This, I am thinking gives the speech frames only. To play this back at the receiving end, do I need to format it into Ogg formatted file before I can

Dear List, I'd like to add text to a plot where a text symbol has both a superscript and subscript. For example, the variable S with a superscript 2 and a subscript t. I have been able to accomplish this using either expression( paste(S,atop(scriptstyle(2),scriptstyle(t))) ) or expression( {S[t]}^2 ) but the spacing isn't quite right (or rather what I'd like) using either of

I have a dataframe say: date price_g price_s 0.34 0.56 0.36 0.76 . . . . . . and so on. say, 1000 rows. Is it possible to add two columns to this dataframe, by computing say diff(log(price_g) and diff(log(price_s)) ? The elements in the first row of these columns cannot be computed, but

Hi all: How to use jitter.c, I see this file is not include in the lib. Sorry for this newbie Q.

I apologize for what may be a newbie question: I have two sets of data, one is X,Y,Z data that I'd like to make a contour plot of (Z defining the contours), and a second set of X,Y data (Y as a function of X) which I would like made into a line plot OVERLAYED on the contour plot (X and Y from both plots are in the same units and will have overlapping values). Any suggestions on how to do this

Hi Matt, All, Thanks for looking into this and your suggestions. I compiled the program with -O3 optimization level (clang -O3) on X86_64 target. After your suggestion, i ran the program with iteration of 10000 runs and found that average runtimes are (attaching data collected as well) Forward loop traverse : 2.006 milli seconds Reverse loop traverse : 1.531 milli seconds Yes, i agree that

Dear All, I would like to ask a question on how to do overlay plots in each subgraph of xyplot. 1. I did simulations for m=1000, 2500, 5000, 10000, as the sample sizes. 2. for each sample size value m, 4 graphs are generated; each graph contains overlayed comparisons between 4 methods, 3. now I want put them into a 4-by-4 plot by xyplot, i.e., 4 sample size values, each of which has 4 plots.

Hi Vishal, Ruijie, Thanks for your interest in the project. To get started, the first task would be to merge the 5 patches on top of trunk llvm. The list of patches are listed in the project description: http://llvm.org/OpenProjects.html#llvm_mergesim Please create an account in llvm phabricator (reviews.llvm.org) if you haven't already, and put your patches there. Let me know if you have

Hello? My name is Hyeonwoo Oh. I?m developing video conference software using speex library. Can you give me some sample codes for acoustic echo canceller and noise reduction? I tried noise reduction API, but failed. Normal encode/decode API is working well. Thank you very much for your good job. I?m very pleased with speex. Best regards, Hyeonwoo Oh

Hi, I'm attempting an one-to-one migration from courier-imap to dovecot-imap. current state: Imap-server has a self signed certificate Every client/user has a self signed client certificate that is used for SSL/TLS client authentication. All certificates are self signed "standalone" cerfificates - no CA hierarchy/structure is made. With courier-imap we could just put every

Hi useR's, Has anyone used the "Lars" package in R before? If so, is there any tutorial (not manual) or worked out example online for this R package that one can go through to figure out how one can use this package with lasso regression? I appreciate any help I can get in this direction. Sincerely, Vishal -- *Vishal Thapar, Ph.D.* *Scientific informatics Analyst Cold Spring

I am trying to download a bunch of files from a server, for which I am using download.file( ) within a for loop. The script is working fine except until download.file hits a URL which has no file, at which point it exits. I want to change this behavior to simple log the failure and maintain state within the for loop and iterate to next. I read about try / tryCatch but am having trouble
