Help with csh, read in a file line by line

Shell Programming and Scripting
1

I want to process some audio with:
sox $audio1 $audio2 trim $start_time $dur

How can I batch process them by read in a file containing the values for the variables above on every line, like:
1.wav 1.5 1
2.wav 2.5 2
...

I tried "foreach f (`cat file`)" but cannot read in line by line, and I just found that these is no env variable IFS for csh. Should I use bash script?

Thank you very much
