Audio delay

[Bruno Verdi]

Hello guys

I know we all have already discussed about the audio delay.... but, is there something we can do to avoid the following process.....

" When you speak, your audio is transmitted by the BigBlueButton client to red5 using speex codec. It is then transmitted by red5 to FreeSWITCH (via red5phone), then FreeSWITCH mixes in the audio, then the resulting audio stream is sent back to red5phone (via SIP), and transmitted back to the client. "

Or, the audio delay depends on the system hardware requirements....?

Can you give a hint?

Thanks

Best Regards

Hi Bruno,

That described the current architecture for the flow of data for the audio packets.  We don't have plans to change it in version 0.81.

If you run BigBlueButton on a LAN environmental (no bandwidth issues) and dedicated hardware (no hardware issues) you will have a good experience.  The architecture for the audio works.

If you introduce network congestion (host BigBlueButton on a network with poor bandwidth, or have users connect with poor bandwidth), or run BigBlueButton on an overloaded VM (no dedecated CPU), audio quality will degrade.

I'm not saying that the audio architecture is optimal -- it isn't, but there are factors outside the BigBlueButton server (server network, user's internet connection, host server) that can make it difficult for BigBlueButton to properly receive, process, and transmit the audio packets in real-time.

Regards,... Fred
