similar to: Help forcing crosstalk

Hi All, I'm struggling with an intermittent crosstalk issue resulting in a caller's audio being broadcasted to other calls (only one way as they are unable to hear the others listening in). Doing do diligence I've scoured the web in hopes of triaging the issue. So my thoughts are leaning towards this NOT being an Asterisk issue, but instead being related to the telco (PRI)

Hi, Has anyone ever experienced crosstalk with sangoma analogue cards on 64bit? We have exhausted every test to try and replicate this and find a solution with Sangoma tech support, but we can not fix it. We are about to try the card and four *seperate* UK BT lines in a 32bit system. The current system is a 4gb, dual core cpu with pbx in a flash 1.4, Zaptel and Asterisk 1.4.21-2 Currently we

Hi, One other question I was wondering about. Is the reason that we hear the crosstalk with fec and packet loss percentage>0 is that Opus uses information from the left channel to try to error correct the right channel and vice versa? I am trying to understand the origin of the crosstalk. Thanks. -Jon > On Jan 27, 2017, at 12:29 PM, Jon Lederman <jon at soniccloud.com> wrote: >

Hi Jean-Marc, Thank you. Yes, we do need both channels independent. So, if we encode each channel separately, we will be sacrificing the compression ratio we would achieve with stereo encoding, correct? So, based on what you say here is my understanding. Please confirm this is correct or not: 1) If we use fec, we can reduce cross-talk but increasing bitrate. However, that should result in

Stereo makes two assumptions: 1) It assumes the two channels are somehow correlated 2) It assumes the two channels are meant to be

Hi, Every package I try to install in R i get the same error "had non zero-exit status". I use Ubuntu 18.04.1 LTS how can i fix this? Thank you This shows up when I try install.packages("Rcmdr", dep=T) Error : package ?htmltools? was installed by an R version with different internals; it needs to be reinstalled for use with this R version ERROR: lazy loading failed for

Thanks. When you say that with fec enabled, the threshold is increased, do you mean the bitrate - i.e., you need higher bitrate with fec enabled to suppress crosstalk? Also, can you make any recommendations to decide whether to use fec or not? We are trying to tune the parameters appropriately. Audio quality and reduction of crosstalk are critical for us. Thanks again. Jon Sent from my

Hi, Is it possible to stream live, as opposed to recorded, OGG format yet? I had a look at the Icecast 2.0 beta instructions and it ends in a program called "example" which will stream a pre-recorded OGG file to the server. Is there anything to stream directly from the soundcard yet? If not, is there anything in the pipeline? If it is possible, what bitrates in mono/stereo are

Correct. Another effect I forgot to mention is that Using FEC will actually force SILK/hybrid rather than CELT, so it's possible that disabling FEC makes you use CELT, which

Hi all, I have played a bit with the "reshape" package and function along with "melt" and "cast", but I feel I still don't have a good handle on how to use them efficiently. Below I have included a application of "reshape" that is rather clunky and I'm hoping someone can offer advice on how to use reshape (or melt/cast) more efficiently. #For this

Hi- I'm wrestling with some of my data apparently not being called into a GLM or an LM. I'm looking at factors affecting fish annual catch rates (ie. CPUE) over 30 years. Two of the factors I'm using are sea surface temperature and sea surface temperature anomaly. A small sample of my data is below: CPUE Year Vessel_ID Base_Port Boat_Lgth Planing SST Anomaly 0.127

In the process I installed via CRAN from the menu several packages. One installation, exactRankTests, had a distinct anomaly.

I've got a problem with a samba installation performed by another user so details of the installation are not known but hopefully someone out there has run into the same problem and can give me some information on a possible fix. One of our Samba servers seem to be doing a significant amount of crosstalk with a couple of our other Windows NT servers, I haven't been able to pinpoint what

Greetings- a reviewer for a paper of mine noted an anomaly in some models I ran using glmmPQL (from the MASS package). Specifically, the models are three-level hierarchical probit models estimated using PQL under R. The anomaly is that the log-likelihoods decrease (or, alternatively -2logLik increases) as variables are added to the null model. This is unusual, and I'm trying to figure out

I have the following function for which I need to find the root of a: f <- function(R,a,c,q) sum((1 - (1-R)^a)^(1/a)) - c * q To give context for the problem, this is a psychometric issue where R is a vector denoting the percentage of students scoring correct on test item i in class j, c is the proportion correct on the test by student k, and q is the number of items on the test in total. I

FYI, by "it did, completely" I meant it failed completely. Even if the only file we have to have on the cluster FS (which now seems to be down solely to the ctdb lock file), I'm still worried what these failures mean: 1) does the -rw (without -m) test suggest any problems with the MooseFS FS I'm serving files to users from? 2) does the mmap test failure mean I should not

Hi Chaps, A couple of Sun Netra t105 have been donated to the CentOS Project. The machines are located in London and I was wondering if anyone in the area might be able to host these machines for us ? They come with 19" rack rails. We would need access to some - but not a whole lot of - bandwidth. We plan on using these machines in developer roles, for code testing and sandbox builds.
