Re: [Discuss-gnuradio] Cant receive .wav file correctly

[Haaris]

Hi all,

Thanks for the reply martin.

The dpsk mod and demod work alright with the packet encoder and decoder that i am currently using.

This flow graph recovers a text file somewhat alright. One problem is that even though i have selected overwrite data in file sink, it still appends the recovered data again and again. The second is that every time first 412 characters of the data are missing of the start paragraph. As repeat is turned on in file source, when the data is repeated there are no characters missing and all the data is successfully recovered after the first time. e.g.

data = x x x x

          x x x x

          x x x x

recovered data with repeat on = x x        (412 characters missing)
                                               x x x x

                                               x x x x
                                               x x x x
                                               x x x x

                                               x x x x
                                               x x x x
                                               x x x x  ....

So what happens with the wav file sink and source, why does file sink and source miss the starting 412 characters everytime when recovering data and why does the file sink does'nt overwrite the data?

Thanks in advance
