    other API than winsock for data transfer?

    Hi guys! Well, this project was for the school: I had to transmit sound via Fast-Ethernet and avoid TCP/IP because it had to be really fast. I found the way to transmit data with MAC adresses : I used QNX (real time ) and wrote my own drivers in C. Thanks for the answer, too bad you didn't see...

    synchronisation ???

    Well,12MB is better... ;-) Do you know any function that read "x" bytes every "y" microseconds? There is no other way to play with time other than with CPU speed? I know that I'm going to have trouble trying to make real-time with Windows... Windows is not a real-time OS...

    synchronisation ???

    Well, I meant 64 bits at 192 kHz... Now, I m trying to take a sound file with samples of 24 bits for each channel and transform it in the AES/EBU format : 2 channels of 24 bits + 8 bits of control, that makes 64 bits. AES/EBU is a transport protocol of uncompressed sound but I dont have any...

    Synchronisation ????

    Hi!! I read 64 bytes from a file like this: ifstream in ("music.wav", ios::in | ios::binary ); in.read (buffer,64); What do I have to do to read these 64 bytes 192000 times a second? (192kHz) It's to simulate an input that recieve sound samples at 192 kHz.... Thanks a lot for any...

    Thanks William, now I remember from school... I found some codes with streams and I think I m going to try this way, but thanks anyway! Starn #include <iostream> #include <fstream> #include <iomanip> using namespace std ; const int LGMAX = 20 ; main() { char nomfich [LGMAX+1] ; int n...

    WAOW, thanks! It's the first time I got an answer so fast on this forum... Actually, it's the first time I got one...eh, two answers! It's maybe because my last questions were a bit weird or stupid... ;) Well, yes! At the beginning, I wanted to play a CD on a computer, send the datas with a...

    read a file, cut it, send it...

    Hi! I would like to take a wave file for example, read a part of it (for example 64 bits) and send it via a UDP client to a server. I already got and understand the UDP part but I don't know how to open the file, cut it in pieces,... thanks a lot for any help and sorry for my english...

    api to fill in the ethernet frame without working with winsock in C++?

    Hi!! I would like to find an API to fill directly in an ethernet frame without using the TCP/IP protocol (winsock)in C++. Does anyone knows about such thing? Thanks for any help and sorry for my english! :) Starn
