Hi all! Thanks for your work here. Do you know if this would work on a project with multiple tracks?
Suggestion: in cases where the files are not named in sequence according to time of creation, you can replace this line:
find $DATA -name "*.au" -print0 | while read -d $'\0' FILE ; do
with this:
find $DATA -name "*.au" -printf "%T@ %Tc %p\n" | sort -n | awk '{print $NF}' | while read -d $'\n' FILE ; do

Thanks for the script. Modified to use BleuLlama since I use a mac. Also used
if (( ($COUNT % 2) == 1 )); then
because I needed to recover a stereo recording and pairs of audio clips represents left and right pair. I only needed to recover at least one half of the channel.
