problems with sound convertion example
Hi
Below is my code for a soundconverter (or atleast the beginning of one). By now i have only gotten to the sound convertion example in the java tutorials.
I keep getting this error:
Error: failure attempting to read /home/carsten/Desktop/1-welcome.wav!
I have given the file a chmod 777 permission.
im on linux, but i guess that shouldnt matter.
Hope you can help me out
the problems are in the convertFile method
Thanks
Carsten
