Hello,

If I have raw alaw or ulaw (or other codec) of audio I get in a socket. How can i play that data in Windows ?
Please note that I haven't developed for Windows for over 7 years now, so a good tutorial or Pascal code will be very good help in this manner.

Thanks,
Ido

Using the SDL library works very well for me. It's cross platform. I'm not sure what codecs it can play, but it works for the formats I need.

I can say exactly the same about portaudio.

The mmsystem unit iirc. THen start googling interesting functions.

Thanks all,
For now it appears that the project will not take place, but it is interesting regardless of that.

Something for the archive then;

I forgot to say that the project I researched this for was finally done using these components:

http://www.lakeofsoft.com/vc/

They come with full source, and probably can be made to work with FPC/Lazarus

Thanks, that interesting.

When I'll have a bit more time (now I'm working more then 110% including many of my weekends) I'll open source some things I made in the past with Lazarus and also create a decent Linux Soft phone in Lazarus :)

The original project of the soft phone will not take place at the end, so I'll just continue binding Sofia-SIP that I started and release it for all to use (LGPL) at the moment.
