[SoX-users] Using crossfade_cat.sh and several wave files

[RT <rat...@gm...>]

Greetings

I have several wav files all in the same directory along with
crossfade_cat.sh
I use a script to crossfade multiple files together but I'm getting a
syntax problem.

The script I run is
#!/bin/bash
crossfade_dur=1
i=0

for file in *.wav
do

    i=$((i+1))

    if [ $i -eq 1 ]
    then
        cp $file mix.wav
    else
        crossfade_cat.sh $crossfade_dur mix.wav $file auto auto
    fi

done

But I get an error in the line
"crossfade_cat.sh $crossfade_dur mix.wav $file auto auto" saying
"crossfade_cat.sh: not found"  the thing is I have all the files in the
same directory, and made them executable.  PS I'm using ubuntu 14.04 64bit.

How can I fix this?
