Using the program

This is a command line program, you need to type the commands into a terminal.

Let us assume you have an audio file called long_audio.flv
and you would like to have a file called track.flv which contains a period of the first file.
The first thing is to find the time of the start and the end of the track you want to copy. This program can not help with this, but I have found standard music players do a fine job if displaying the time as they play. This makes it reasonbly easy to find the begining and end of the track required. This needs to be converted to msec, first convert to seconds then multiply by 1000 for msec.

time 46:32 is 4660 = 2760 plus 32 = 2792 gives 2792000 msec
or
time 1:12:02 is 7260 = 4320 plus 02 = 4322 gives 4322000 msec

The command line then becomes

flv_trim long_audio.flv track.flv 2792000 4322000

The original file is not changed in any way, so just experiment.
