Below is the tutorial I created back a couple months ago. I've since needed to do some more audio editing, and made it much easier with the installation of my Audigy 5.1 card.
We recorded a live concert of Montague Street (soon to be online). There was a single audio track that I needed to split up into the appropriate songs. There was no need to merge anything together, so it was fairly straight forward and easy. I used Audacity to load, cut and adjust levels and create multiple mp3 tracks.
Read on if you want to see the hard way of doing things... or more just for the Audacity instructions.
Original..
So here is a little tutorial on editing sound files. I had to do this for a couple tracks for Laura's website (here)
I'll just start this off with the programs I used to do this. I'll also mention that my computer audio really doesn't like Linux (any flavour), and though I own a sound card that would work fine, it's sitting in a bag not being used...
Sound Juicer (Audio CD Extractor)
Audacious
mp3wrap
Audacity
Installation
Sound Juicer, Audacious, Audacity:
Applications > Add/Remove > Search 'audio' > Mark Programs for Installation > Apply Changes
mp3wrap:
from a terminal window
sudo apt-get install mp3wrap
Sound Juicer:
Load CD - Disc > Re-read Disc (CTRL+R) if needed
Edit > Preferences > select options here, choose mp3 output if desired
Select tracks to be converted to mp3
Change artist and track information
Extract (folder structure will be created in the folder selected from preferences)
mp3wrap:
again in a terminal window, go to your music directory
mp3wrap merged.mp3 1.mp3 2.mp3
Audacious:
Just a simple audio player to put all the tracks together and give a listen (I used it to find out at which times I needed to cut the track *for unwanted sound at the end - mainly because Audacity doesn't like my sound card/configuration)
Audacity:
Load one file to edit, it will take a little time to import.
The key feature that I used was the cut, or simply the delete key.
I found the section and time (zooming in can help be more precise)
highlighted the unwanted section and pressed 'delete' (the cut button also works)
You should be able to listen to your newly modified track. If needed silence can also be inserted.
To maintain the mp3 format you will need to export the track, being sure to choose mp3 as the output type.
Repeat for other files that may need editing.
If needed to test again you can load the files back into Audacious; or if you overwrote the files should be able to just play the list again.
Now these edited files are being used on the website; not much time needed to get them cleaned up.
