Audio streaming components and libraries

[phyx3r]

Hi, i'm using the VCX enterprise library to make a custom voip client/server architecture. I've a problem with the sound playing on the client machine. The sound is very scratchy on the client and is perfect on the server. I'm using the ipserver/ipclient components as seen in the demos projects. I've made a test with the waveriff player too and the sound is ever scratchy.

My client application was tested on two different developing machines and the results are the same.

What can be wrong? Is there a way to chose the driver to use (eg. Asio, DirectX...) or does it directly use the audio device?

Thanks!

Try changing the codec you setup on server machine. Codec is specified by FormatTag property, try 49 for GSM (it support only mono) or 2 for ADPCM.

Our libraries use only ACM and MME interfaces, so drivers should not matter.

I don't think that it's a codec problem because I've tried to play a wave file with the waveriff component and the problem persists: the sound is scratchy. I've tried the same app on two different machines and the problem persists (so it's not an hardware problem also because windows sounds are correctly played).

Do you know about any compatibility issues with any other (.net or third party) components that I might use in my software?

I'll try to change the codec but, in the meantime, do you have any other suggestions?

Thank You very much for the help.

Hello.
We are currently evaluating your product and having a similar problem.
The sound is scrachy when we're building our own project but works fine on your examples. Help is needed, thanks.
