If more than one speaker receives the *same* signal, it doesn't matter the number of speakers. It only gets tricky when the speakers are playing slightly different signals (e.g. from a stereo song).

Hello. I have the following situation. AEC is used in network chat software over DirectSound API. Echo and reference signals are almost aligned (delay is no more than 30ms). When echo is emulated in notebook (built-in speakers + mic) everything goes fine and echo is cancelled. But when configuration includes stand-alone speakers and mic no echo is removed. Audio is in 22050 hz at 16 bit mono format, number of samples to process were 441 and tail was used 4096. Dumps are here: http://rapidshare.com/files/317389...

...top until 200, 220, 240, 260, won't this jb get confused? Or, is it relying on in-band signalling of speex so it will ask speex to predict what it thinks are lost frames, and speex would know that the interpolation should be silence (or CNG). >>Because we need to synchronize multiple speakers in the conference: >>On the incoming side, each incoming "stream" has it's own timebase and >>timestamps, and jitter. If we just passed that through (even if we >>adjusted the timebases), the different jitter characteristics of each >>speaker would create cha...

Is there an ATA type device out there that has low level audio out for connecting speakers? My asterisk server is in one building, I wish to have speakers in another building and connect them up to a low level audio device that I can call into and speak. Can I connect speakers into the FXS or FXO of a grandstream HT 503? Does that work? I'd prefer not to have a PC setting ther...

> You will hit two problems though. The first is that you will need to have > a stream for remote participants to listen to. Yeah, that's right. If you want the remote speakers to be able to listen to the other speakers this becomes a little complicated. If you hear your own voice with a latency more than 1/10 or 1/5 second it becomes very distracting! This latency really is a problem. And mixing a certain signal for every remote speaker also means a huge effort. And yo...

...an Internet radio station. I would like to base our project on linux and Icecast / liveice (right?) but I don't understand some terms of "radio" practices. I need your experience&help; the project should cover the following scenarios: * A broadcast server on spain with a local speaker * A broadcast server on spain and remote speaker (possibly through long distances. For example, the broadcast on spain and the speaker from Honduras ) * A broadcast server on spain and remote collaboration with some speakers ( the local speaker collaborating on the same program with differents and...

Has anyone experienced this before? This happened to me even under CentOS 4.x. But basically what happens is that when I play MP3s, whatever the right speaker crackles at higher volume. And it's always that speaker and only that speaker. If I turn the balance to the other speaker I have no problems. So it feels like it might be a mixer issue. I use Alsa, of course, as that's what the default is. Is this a known issue or does someone know how to f...

...into this. I've decided that the best (from a pure elegance and patent avoidance) way to handle this is to basically decode the 5.1 input into a WXY or WXYUV ambisonic signal, which can then be handled by the Vorbis Ambisonic support. To accomplish that I produced a model of an idealized 5.1 speaker arrangement (with pointsource massless speakers) and a simulated ambisonic microphone at the listening location. I then measured the ambisonic impulse response from each speaker and produced convolution filters for the audio. The nice thing about this is that you can take the ambisonic decoded out...

To all: I am having an echo problem with X-Lite and iaxComm. I am using the monitor speakers and a desktop microphone. My problem is that the sound from the speakers is repeated by the microphone causing an echo that is annoying. Is this correctable? I have searched throught this archives and played with various settings but have not been able to fix this. I have purchased a coupl...

Hi all! Using C6 on an Asus M5A99X EVO R2.0 motherboard with AMD six core FX6300. That board uses Realtek ALC892 audio chipset. For the first time since I got that motherboard I tried plugging in headphones to the front panel speaker output. I was somewhat displeased to note that the speakers don't mute when that happens. I recall seeing info on that in Fedora, but not Centos, and haven't so far scared up how to troubleshoot it. I can MANUALLY change the setting in sound preferences, which offers only two choices: &qu...

I want to use a voip speaker phone as a room monitor. Requirements: A phone that I can set to auto answer in speaker mode. A phone with a good speaker phone. Ability to make the audio one way. I want to monitor the room but not have my voice heard in the room. Yes, the mute button can accomplish this also. I have been u...

This message is long overdue. I've commented on similar issues when other people have mentioned similar items, but I am finally taking the time to to ask this question. Did anyone else have the sound from their internal speaker stop working with the release of CentOS 7.2? I have tested this with multiple machines with the same card and the same issue. The card is identified as: !!PCI Soundcards installed in the system !!-------------------------------------- 00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10...

...ard to do the capture and plaback will *not* work, regardless of what you may think." If this still is true, the Speex echo canceller is basicly a no-go for us. There is no way I can get the customers to understand why they can't use e.g the microphone in their webcam together with the speakers connected to the built-in soundcard, and have to go buying a separate microphone. In the release notes for 1.2beta2, there is the following sentece however: "The echo canceller should now converge faster, be robust and tolerant of incorrect capture-playback synchronisation." This s...

I'm running lmer repeatedly on artificial data with two fixed factors (called 'gender' and 'stress') and one random factor ('speaker'). Gender is a between-speaker variable, stress is a within-speaker variable, if that matters. Each dataset has 100 rows from each of 20 speakers, 2000 rows in all. About 5% of the time I get a strange result, where the lmer() model with BOTH fixed factors and the random factor ('gs_s'...
