    I just posted on our blog about a little script to schedule stream recordings. This is not really a direct Airtime hack, but I felt like sharing it here.

    Here is a simple method to do a recording every hour (Airtime hack)

    go to line 401 and place the following [of course you need to define your own file path and parameters)

    # The output file
    # to be saved with parameters date and time
    # make sure you have permission to the file path
    filename = "path-to-file/recording-%Y-%m-%d-%H-%M-%S.mp3"



    #with a newfile each time its open [append] and open that file every xxx time [reopen_when]
    #{0m0s} is every hour
    output.file(%mp3,
                      filename,
                            fallible=true,
                                 append=true,
                                    reopen_when={0m0s},
                                          on_stop=shutdown,
                                          
                                                         s)

    Now go to your watch folder and place the pathtofile as a folder to watch,you will see all your recording.
    schedule away.

    You can use a switch to tell it when you want it to play.

    My previous post about this is here http://forum.sourcefabric.org/discussion/15915/record-output-to-a-file-every-hour-from-input-alsamicand-icecast-how-to/p1.
     and this cover from line in

    This is especially useful for stations  who want to archive there show daily.
    I found this to be more reliable than sox,ffmpeg,vlc etc.
    you need about 40mb-120mb per hour of disk space

    these changes have to be made in ls_script.liq?

    Yes !
     but here is my easy tip
     
    You can set up  your own includes file and whenever you upgrade just place that line at line 401. like this

    "% include /mypath/mymod.liq"

    one line as a post activity for upgrade

    So if you want to debug  just comment it out #"% include /mypath/mymod.liq"

    This is a hack, but I wanted to control the size of the recording file.  My initial purpose was to maximize what I could burn on a CD and play in the car.  Thank you to Micz Flor.

    Let's call the shell "stream.rip"

    #!/bin/ksh

    URL=$1
    STATION=$2
    MAX=$3

    cvlc $URL --sout file/mp3:$STATION.mp3 2>/dev/null &

    sleep 120

    while (true)
    do
            SIZE=`ls -lh $STATION.mp3 | cut -d " " -f 5 | cut -d M -f 1`

            if [[ $SIZE -ge $MAX ]]
            then
                    killall -v vlc

                    exit 0
            fi

            sleep 60
    done

    It may be scheduled by

        at <time-spec> -f <file>

    where file is

        ksh stream.rip <url> <stream-name> <length-in-MiB>
