Hi, folks: I have used R for some time and have not explore deep inside the codes of the packages. Today, I try to modify some code in a package of arrayQuality (I do not think it matters which package it is). There is a function called maQualityPlots and I use fix(maQualityPlots) that I can view and edit the code of this function. However, there is another function qpMAPlots that I want to edit,

...e possible warning messages. Can it cancel the echo properly? It may announce the "Drift estimate is ..." message if the recorded sound contains not only echo but also other sound like a near-end speech. In other cases, it may truly indicate a mismatch of the sampling frequency.

If the left and right channels are processed separately as you do, the parameter Mic-Number in speex_echo_state_init_mc should be 1, not 2 On Wed, Feb 10, 2010 at 4:00 AM, <speex-dev-request at xiph.org> wrote: > Send Speex-dev mailing list submissions to > speex-dev at xiph.org > > To subscribe or unsubscribe via the World Wide Web, visit >

Hello, I heard that myJoice used Speex as the audio codec. Has anyone experienced its performance? By the way, is it possible to buy it outside of Sweden?

I have been working on a project importing Speex to a embedded platform for a while. When I tried to shut down the macro TWO_PATH in Speex AEC to save space, an error occurred. Dbf is undefined. The 1.2rc1 code is like this Dbf = 0; See = 0; #ifdef TWO_PATH /* Difference in response, this is used to estimate the variance of our residual power estimate */ for (chan = 0; chan < C;

I used to run in the same problem. A difference higher than 3Hz in sampling rate between mic and speaker data can cause a totally failure of AEC. However, I have not seen a proper solution to this problem in real time. If you roughly know the difference of sampling rate between the speaker and the mic file, you may try to resample each frame of mic file according to it. Otherwise, or if the
