Hello all ! I have been experimenting with transmission of audio file in FM range but i could not generate a valid ".dat" file. I would like to know how i could convert an image,video or specially an audio file into a valid ".dat" file format for transmission. Moreover I would like to know what is the format of .dat file used here because so many applications use the file extension ".dat" to indicate a file that contains data. Also at some places it is written that a .raw format is used for audio transmission??? Regards .......

Salman Somewhere on a website I found a way to transmit mp3 files using the USRP. Just can't remember where. What you do is the following: Use sox to decode the mp3 to a raw file: sox myfile.mp3 -r 44100 -l -f -c 1 myfile.raw You can then just open this file in a Gnuradio script and proceed from there. It works. I'm only doing mono at the moment, but I'm sure sox can do stereo. I think Gnuradio has a filetype to import wav files if you need that. Sebastiaan
