similar to: High CPU usage

Hi Mark, Code below: int16_t* samples; int16_t* fbSilenceFrame; void *fSpeexState; float eng(0.f); int speexFrameSize(0); speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize); for (int i = 0; i < speexFrameSize; i++) { eng += samples[i] * samples[i]; } if (eng / speexFrameSize < 3.f) { memcpy(samples, silenceFrame, speexFrameSize * sizeof(int16_t)); } where

Hi Jozsef, this approach sounds interesting. Do have you have some source code available ?

Description =========== This patch adds support of CMake meta build system, so you can generate Unix makefiles, VS 6.0-2017 projects and many more. Features ======== * Win32 and Linux tested * Travis CI test added * Generates working Visual Studio 6.0-2017 solutions * Generates working Unix Makefile * Supported options (<option> - <default value>): * `ENABLE_FLOATING_POINT` - on

Thanks for the help folks, but I got this working a couple hours ago. =) I'm quite please after struggling with it for a few days. I just needed to take each audio tag from the FLV file and feed the contents of the tag (except for the first byte) to the jspeex decoder and write the results to a file. Jozsef - it is possible to specify 8KHz in the flash client and decode it as such. Speex

What are you trying to accomplish? My code sample was about how Flash Player microphone input in speex.

Nicer way: void* speexState = speex_encoder_init(&speex_wb_mode); int speexFrameSize, speexRate; speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize); speex_encoder_ctl(speexState, SPEEX_GET_SAMPLING_RATE, &speexRate); SpeexPreprocessState* speexPreprocessState = speex_preprocess_state_init(speexFrameSize, speexRate); Jozsef -----Original Message----- From: Max

The link is http://www.adobe.com/devnet/rtmp/. TC Message stands for TinCan message. It is 11 bytes long, first byte is message type, three bytes of payload length four bytes of timestamp and three bytes of stream ID. The first byte of the payload for audio message is the format byte and the rest of the byte is the payload. Jozsef ----- Original Message ---- From: Jeff Ramin <jeff.ramin

I have run into the same issue. Before sending a frame to encoder, I calculate the energy. If it is less than a small threshold, I simply replace this frame with "silence frame," which is 320 random samples of values smaller than 3 (16 kHz). BTW, I have only experience this problem with certain USB headsets that provide you all 0 samples when muted. Jozsef

Hello, I have a dataframe containing various time series (not time series objects though!)with hourly time steps. I?d like to perform ccf for I need to know the correlation factors for different lags. Here is an example: x<-as.POSIXct(c("2008-12-25 16:00:00", "2008-12-25 17:00:00", "2008-12-25 18:00:00", "2008-12-25 19:00:00", "2008-12-25

Dear R friends, I want to compare two datasets and I get the message Error in .Call("cpermdist2", ma = as.integer(m), mb = as.integer(col), : negative length vectors are not allowed after specifying the exact test. I'm using the exactRankTests package. Do you suggest me using the coin library, or is there anything "wrong" with my data? Kind regards, David --

Dear r-helpers, I estimated a generalized additive model (GAM) using Hastie's package GAM. Example: gam1 <- gam(vegetation ~ s(slope), family = binomial, data=aufnahmen_0708, trace=TRUE) pred <- predict(gam1, type = "response") vegetation is a categorial, slope a numerical variable. Now I want to assess the accurancy of the model using k-fold cross validation. I found the

Moika, Overnight, I migrated my user-mails from uw-imap to dovecot-maildir. I used the uw2dovecot.pl script to convert all mails and changed exim, too. Receiving mails works fine allready, but nobody can access the usual subscribed folders with thunderbird. Via "subscriptions" I can find the converted folders in a folder called "_" (underline). People getting mad about me

Dear list, I am looking for an implementation of random rotation matrix generation in R to do a rotation test: I want to use the matrices to create random multivariate normal matrices with common covariance structure and mean based on an observed data matrix. The rRotationMatrix-function in the mixAK-package is an option, but as far as I can tell I need to draw rotation matrices with determinant

Sounds strange. Can you reproduce the problem with speexenc/speexdec? If so, can you send a short file that triggers that along with the exact command line?

Is there a document somewhere that describes speex-encoded FLV files? What is a TC message? Thanks. Jozsef Vass wrote: > FLV contains TC messages? TC message payload contains a format byte and speex frames (up to eight). In the format byte 0xb0 indicates speex.

rtmplite -- http://code.google.com/p/rtmplite/ -- can be used to record Speex .flv audio and a/v files from Flash/Flex applets, and ffmpeg can be used to extract the Speex audio from such files, which can also be replayed on Flash. > Date: Tue, 23 Aug 2011 14:53:52 -0700 > From: Jozsef Vass <jovass at adobe.com> > > The only way to do this is to publish from Flash Player and

Hello, since a couple of days I'm trying hard to elicit a certain thing out of the Sweave function of R. Unfortunately I'm quite unsuccessful. It's only about a small, ridiculous minus sign, which does not appear in the final pdf of a latex file, if I try to incorporate the Computer- Modern fonts into the plot. It seems, that R uses different encodings for minus signs, which are put

Hi, I was wondering if it is possible to put a dovecot managed maildir under a vcs like system, for example git or bzr. I'd like to have a seamless history of all mail going in and out of my mailboxes, so a vcs like system seams a good choice for me. I'm not quite sure however if that would cause any problems to dovecot and what the best way of handling commits would be. If anyone on the
