Re: [Ekiga-list] Bad sound quality because of missing low pass filter
On 2010-03-02, Christian Jaeger wrote: Hello I'm using Ekiga and Twinkle with the Diamondcard.us service as my main phone service. People are telling me every now and then that the sound quality is pretty poor, and in fact when I listen to my voice on the echo service it's always been quite much worse than when using a normal phone I think. It's regardless of the codec used, all that are offered by Diamondcard are using 8000 Hz sampling rate. And I'm using a headset and have checked sound quality locally, which is just fine, as I can verify for example with (the bfr command is to delay playback, so you can hear the echo better): arecord -t raw -f dat -r 22050 -c 1 | bfr -m 33075 | aplay -t raw -f dat -r 22050 -c 1 - Now 8000 Hz is of course lower, and in fact when using that rate: arecord -t raw -f dat -r 8000 -c 1 | bfr -m 12000 | aplay -t raw -f dat -r 8000 -c 1 - it sounds exactly as in the echo test. Now one thing I know is that if you sample a signal, you need a low pass before the quantization, at half the sample rate or lower, to remove frequencies that are too high to be represented in the digitalized data. If the low pass is missing, the high frequencies are turned to noise instead. So what happens when a program samples data at a low frequency, will it somehow make the sound card tune a low pass to the correct cut-off frequency when the sample rate is changed? Sounds rather unlikely, and in fact the echo test at 8000 Hz sounds exactly like suffering from that problem: you can't distinguish s from f anymore, which may just be unavoidable with no frequency spectrum above 4000 Hz, but worse, they sound very loud and noisy, and for example an combined s and vowel, like they often appear in french (e.g. bourgeoisie I think, I'm not a native french speaker), sound really awful. Now there's a way to remedie this: low-pass filtering can also be done computationally, so we can digitize at say DAT quality (48000 Hz) and resample down to 8000 samples/second programmatically, which is what the following command line is doing: arecord -t raw -f dat -c 1 | bfr -m 36000 | sox -t raw -r 48000 -s -2 -c 1 - -t raw -r 8000 - resample -ql |bfr -m 6000 | aplay -t raw -f dat -r 8000 -c 1 - It sounds more hollow/muffled now, but much cleaner. No loud noises anymore for sharp consonants. Would doing this in VoIP programs improve perceived sound quality for the listener? I would expect so, but haven't been able to test. (All I know is that more often than not I'm using Skype to call people now (Skype-out service), because people are telling me they hear me better.) Note that you can very well say you're wrong, we don't need a low-pass, just use a higher sampling rate then it sounds just fine, which is of course partially true, with higher sampling rates the relevance of a low-pass decreases quickly as the spectrum of frequencies that are higher than half the sample rate becomes narrower (and an increasing part of the consonant frequency range is digitized correctly instead of as noise). But given that at least Diamondcard only offers 8000 Hz, and there may be valid reasons for this (like maybe the phone system is still using that frequency), what's your position on this? You've discovered aliasing. It sounds pretty bad at 8 kHz sampling rate, doesn't it? I suspect you have a poorly engineered sound card. It /should/, as you suggest, have proper low pass filtering, but apparently it doesn't. You can often get away with gentle anti-alias filtering for a 48 kHz sampling rate, but not 8 kHz. Ideally, the sound card would sample everything at 48 kHz and then decimate by a factor of 6 using proper low-pass digital filtering. It sounds as if yours simply sub-samples everything instead, which aliases almost everything between 4 kHz and 48 kHz and folds it into the up-to-4 kHz band. Maybe a better sound card would do what you want. (I'm sorry, I don't have any recommendation.) Dave NICE CTI Systems UK Limited (NICE) is registered in England under company number, 3403044.

Re: [Ekiga-list] Video Problem with Ekiga on Windows XP Pro
In fact I've received video on the Windows 2.0.11 beta too. The only thing I haven't had working is simultaneous transmission and reception of video, since I only have one webcam handy. Windows XP Pro. This is on the company's LAN where there is no SIP server of any kind and no SIP access to external providers.

I have to compliment your efforts - Ekiga is a very nice piece of software !! I have successfully installed Ekiga on 2 PCs (PC1 and PC2) on my home network running Windows XP Pro on both PCs. The software installed beautifully on both PCs. I was able to configure SIP through my Asterisk Win32 Server (On a third Windows XP PC - PC3). I can make full duplex voice calls through Asterisk WIn32 using Ekiga between PC1 and PC2 with no issues. What I really want to do is video conference between PC1 and PC2 through Asterisk. I have not set up a SIP account on your web site - I just want to do SIP calls on my private network. PC1 has an older analog video capture card - Pinnacle DC10+ installed. I have an old VHS video camera plugged into it. It works very well under Windows XP and is recognized by Ekiga. I can see the video from the DC10+ on the local screen under Ekiga. PC2 has a newer USB video camera installed. It also works very well under WindowsXP - although it is slower and with much poorer resolution than the DC10+. The USB camera is also recognized by Ekiga on PC2 and I can see its video on the local Ekiga window. When I make a call from PC1 to PC2 I expected the video from PC1 to be visible in a window on PC2, and of course the video from PC1 on a window on PC2. This does not happen. I only see the local video on both PC1 and PC2. Under the view on both Ekiga installations I see the options for Remote Video, Both(Picture-in-Picture), Both (Side-by-Side), and Both (Both in New Windows) - but NONE of these options can be selected - they are grayed out. Should this be working ??? Do I have something configured incorrectly ? Do I have to purchase an upgrade ? I have successfully configured another piece of Video conference software (Zoomcall Pro) and the video from these same PCs works fine in video conference mode. Unfortunately Zoomcall REQUIRES you to communicate through their server on the Internet. I don't want to do that - I want to stay on my private network. Please help any way you can. Also - as you might have guessed - I have quite an elaborate set up in my lab area so I would be willing to test any new software you might need a third party to test. Thanks, Kevin Komara * Kevin J.

Dave, I did that, but http://emmanuelfavrenicolin.free.fr/Public/Divers/Wireshark/20 071120_wireshack.libcap first transmitted RTP packet [snip] This is quiet but not silent. 5th [snip] Similar. last transmitted [snip] This looks like convincing audio, definitely not silent, not even quiet. last received [snip] This is quiet but not silent. Is that make sense Yes. There is another problem. The flux (payload) on eth0 is at the beginning not zero, but then it rapidly becomes zero byte/second so that I expect that absolutly nothing else is transmitted. I observed 2 cases. 1) the transmitted bytes (meekiga.net) becomes zero before the end of the woman blablabla and then the received bytes/ (ekigame) becomes zero too 2) Both transmitted and received bytes fluxes becomes zero when the woman ends up her blablabla You mean that there are no more packets being received and/or transmitted? That would be wrong, but it would explain why you can't hear the echo. You should be transmitting continuously, 50 packets per second, for the entire duration of the call. I can't be so sure about what you should receive. If the echo is of (say) 4 seconds of speech with a 4 second gap between them (for you to record in), it's possible that the packets will only flow from ekiga.net to you during the times that you should be hearing something.

I'm referring to what I hear when I run the audio test in the installation process. I can hear other sounds in the headphones OK, so I know that audio out is working OK. I have the impression that there's a mismatch in the sampling rates. I opted to install with a sample rate of 8000, which wasn't offered in the list, it had to be a custom sample rate. I need 8000 as I need to be compatible with common telecom sample rates.

The sound system is Realtek AC97 Audio for microphone and playback. Can anyone suggest what might be done to fix the problem? Have others experienced the same? The sound audio test runs at 16 kHz. But when making calls, it will use 8 kHz or 16 kHz depending on the codec being used. I can not really help for your audio problem though, it seems to be some kind of hardware driver problem. I don't think so. I just used Cool Edit 96 to record a few seconds of my voice and play it back. This uses the same drivers as does Ekiga - but Cool Edit records and replays fine. I set Cool Edit to record in 8 bit mono at 8000 Hz. It has to be something about the way Ekiga uses the drivers, doesn't it?
