simplex real-time audio multicasting in a local area network

Postby azing010 » March 15th, 2007, 2:21 am

hi guys,

im az, im really in need of help regarding my project, its a simplex real-time audio multicasting in a local area network.

i tried working on the wave audio components and the demo (using the live audio) that i downloaded here. but there seems to be an obvious delay, about o.5+ seconds,. was it with the coding? can it be tried other coding instead of wav coding? because it consumes more bandwidth?

how can you achieve a realtime transmission same as on the phone? voip?

unfortunately, im really just beginning to learn delphi on my delphi 7,. ill be very very greatfull for any help.. please..:)

lotsa thanks

az

This delay exsits even on Phone and VoIP. However the humen brain cannot recognize delays less than 100ms (or something about this, I don't remember the exact value).

While using LiveAudioRecorder/LiveAudioPlayer to transfer audio, decrease the buffer length and increase the buffer count to reduce the delay.
