Hallo,
I would like to pass some data from a shell to a pd patch that is on
another machine in the subnetwork. I have solved most of the troubles
using nc in the formmore junk | nc 146.50.10.35 9000
and putting my patch with netsreceive on port 9000.
My problem is rather banale for you guys, but i had not find a
solution in the archives of the list...but how do i translate these data (floating point values in between
0 and 1) in audio signal? The data represents a 8khz sample of sound....
fredd,
what you want to do sounds pretty interesting.
some tips: as far as I can remember, you will want to add ";" to all of your values that you send over the net. the ";" is Pd's end of line character and I believe netreceive will expect one for each value.
on the pd end, you probably want something like this:
[netreceive 9000 1] | [$1 10( | [line~] | [dac~]
for that example, inorder to hear something, you would want to scale your original data to be in the range of -1.0 <-> 1.0 (not 0.0 <-> 1.0)
but, I just tried it now and can't seem to get nc to send more than just the first value.
I try: cat file.txt | nc -uv localhost 9000 (the "-u" is for udp)
the file.txt looks like this: 0.41; 0.31; 0.31; 0.21; 0.11;
but "nc" seems to hang with the first value of 0.41, not sending the rest.
best of luck.

This command adds ";" at the end of every line of a text file before to send it. Then, we would just need to create a fifo with something like tail -f in order to create a udp channel to pd.
cat data.txt | while read line; do echo "${line};" | nc -ub -q 0 localhost 3001; done
