[NTLUG:Discuss] how can I copy the last 'x' minutes of a MP3 file?

[Jack Snodgrass]

Thanks. mpgedit seems like it will do what I need. 
I've already gotten it to crop just the last 5 minutes
of my .mp3 file that I'm testing with. Works really fast. 

I use this ( below ) to record the audio... I'm pretty sure that 
it's not optimised for AM Radio, mono ( non-stereo ) 

/usr/bin/arecord --quiet -f dat -t wav -d 3600 | /usr/bin/notlame -S
--nohist --quiet --silent  -B 128 -

so I use arecord to record off of the line-in jack and then I 
pipe it to notlame to build the mp3 file. This lets me listen
to the .mp3 stream as it's being created. I can pause/stop/rewind,
etc while the .mp3 stream is created. 60 mintes of recordings is
around 6meg....

I'm not sure how/where I'd say 11khz, mono in my record script 
that I'm using. Need to look at the arecord and notlame options.
