Speaking voice of host gets altered

Hi,

I found an odd thing as I tried to host a phone meeting. I was the host and my voice was altered in a way that makes it sound like I would have been boozing for a month. More precisely the pitch was lowered.

I had one participant and his voice was OK even though he was using Linux.

My setup was tested right the Dimdim test with Skype and it was OK.

OS: Windows XP SP2
Browser: Firefox 2.0.0.13

Hi,

I found out that this problem exists only with Linux users.

Also:

Sound from Windows host to Linux -> pitch lowered and a 1-2 sec delay
sound from Linux to Windows: OK
sound from Windows to Windows OK.

Strange...

Would it be possible to hide the domains of the users' email addresses on this forum? This would be quite polite as we beta users cannot choose our usernames.

Thank you for the feedback.
Can you please give me some additional information.
If you click on the green or orange button in the Audio Broadcaster - what is the value of the latency & Upload and Download bandwidth that you see?

Regards,
Uday

Hi,

Latency is between 130 and 200 msec
Up 36 - 83 kbit/s
Down 356 bit/s

I was able to replicate this problem: I had a friend in the same session about 700 kilometres away and the sound was crisp and clear in his windows PC. My Linux PC next to the Windows PC I am using as host gave me the altered sound at the same time.

Hi

I would like to point out that the measurements by the applications don't seem to be correct ( not to say that something is wrong but they might be messuring something else, like time to server and not time to server to client), I have also tested and measured the latency and the upload and download on both the attendee and the presenter. During my meeting I experience about 2.4 seconds delay . The download for sound is around 2.5 Kb/s and the picture transfer was 600-800 Kb/s (this varies greatly by Internet speed, there are only short burst of high data transfer on high speed connection, T1 , whyle on slower internet there would be longer and slower download).

This happened to me yesterday. We were trying dimdim for the first time.

Meeting was hosted on an XP with 2 OS X (Leopard 10.5.2) machines joined. My voice, on one of the macs, was pitch altered and slowed. The other mac was fine.

I could hear voices fine, they just couldn't hear me fine.

So it has nothing to do with the host, nor with Linux.

I seem to have the opposite problem. I host on a linux machine and my voice is faster and higher pitch coming out the attendee's side. Any solution to that? Unfortunatly, I don't have any additional numbers to give you at this time. Let me know what you need and how to get it and I'll pass it along..

I had the same problem a couple of days ago and again yesterday while trying out dimdim for the first time. The meeting was hosted by me on a PC with Windows XP and my friend was participating on a Notebook with Linux.

My voice sounded - well, horrible is an understatement - way too low and slow. In the end we switched to Skype and continued that way.

It would be great to get a solution for that Thanks!!

Regards

We hosted a dimdim session with up to 16 participants.

The host was on a winXP machine. Most participants were on winXP or perhaps winVista machines. I was using Linux (Ubuntu 7.10) and the sound of the host was terribly altered. I was on a wireless connection but it was not a slow connection at all.

I used my camera to record 40 seconds of the session. My recording was interrrupted by room service at the hotel but you can clearly hear the distortion in the first and last 10 second segments of the video. The office Linux machine is on a land line.

I have used dimdim with the same version of Linux (Ubuntu 7.10) at my office without any problems.

I will try to capture the numbers asked for above if I experience the problem again and I will post the numbers here.

Thanks for creating and sharing Dimdim - it is really great!

I need to add that the voice distortion only happened with audio from the moderator's microphone. When others were allowed to speak their voices came over loud and clear.
