I am trying to make an application that use audio streaming through TCP connection, Using Delphi 7 and Indy9.
More clearly, How i can stream input from Client microphone and send it to (TCP or HTTP Server)? Consider real time.
Thank you

How are you recording the stream? What format? – Marcus Adams Nov 11 '13 at 21:26

2TCP is not the best choice for real-time streaming. Most streaming protocols are based on UDP instead. The early versions of Skype were written in Delphi and used Indy UDP components, for instance. – Remy Lebeau Nov 12 '13 at 05:57

I never did this, but I think you can start with the basics ...
Set the frame rate to be used, 8000hz is a good choice
Choice a chunk size to capture from Microphone (1024, 2048, 4096,
etc)Capture the audio from Microphone in short int or float32 (RAW Audio)
Put this chunk in one socket buffer preferably UDP, and send to
another side over UDP connectionIf you make a loop with this process are you sending audio data by
socketNow The other side just need get the data from every UDP connection
and play
This steps are a basic audio streaming :-)
In the future you might want to work with queuing, but that's another story
